Background:
Vascular aging is a major driver of cardiovascular, metabolic, and degenerative diseases, characterized by oxidative stress, mitochondrial dysfunction, endothelial senescence, and impaired proteostasis. Emerging data show that anti-infective drugs can influence these aging pathways beyond antimicrobial activity. However, their capacity to accelerate or slow vascular ageing has not been clearly defined. This review summarizes current evidence on how anti-infective agents modulate vascular ageing mechanisms.
Methods:
A systematic review was conducted following PRISMA 2020 guidelines. Studies from 2000 to 2024 were searched in major indexed databases. Eligible studies included in vitro, animal, and human research evaluating the effects of anti-infective agents on endothelial function, vascular senescence markers (p16INK4a, p21, SA-β-gal), oxidative stress, mitochondrial activity, inflammation, or proteostasis, key determinants of vascular ageing. Studies lacking mechanistic aging endpoints were excluded. Extracted data included drug class, model type, study design, and age-related outcomes. Risk of bias was assessed using SYRCLE, RoB-2, ROBINS-I, and narrative appraisal for in vitro studies.
Results:
Ninety-eight studies were identified; after removing six duplicates, ninety-two met the criteria. Macrolides, tetracyclines, and selected antivirals exerted anti-ageing effects by suppressing senescence-associated secretory phenotype (SASP), preserving mitochondrial integrity, reducing oxidative stress, and enhancing autophagy. Aminoglycosides and fluoroquinolones accelerated vascular ageing by generating reactive oxygen species, inducing DNA damage, and disrupting proteostasis. Antiviral protease inhibitors worsened endothelial dysfunction and metabolic aging. Antifungals such as itraconazole and amphotericin B impaired mitochondrial activity and angiogenesis, contributing to ageing phenotypes. Antiparasitic drugs showed mixed aging outcomes: chloroquine promoted autophagy and longevity, whereas thiabendazole impaired vascular stability. Broad-spectrum antibiotics disrupted the gut-vascular axis, increasing trimethylamine N-oxide, a mediator of inflammatory vascular aging.
Discussion:
Anti-infective drugs display diverse, class-specific effects on vascular aging. Recognizing these age-related actions is essential for safer prescribing and for repurposing anti-infective agents to target pathological vascular aging mechanisms.

Aim:
The prevalence of multidrug-resistant “superbugs”, particularly Acinetobacter baumannii and Klebsiella pneumoniae, is a menacing phenomenon in society, rendering last-resort antibiotics increasingly suboptimal and ineffective. Carbapenemase enzymes play a major role in this resistance by hydrolysing carbapenem antibiotics. This study aims to identify and characterize potential non-covalent carbapenemase inhibitors using multiscale computational approaches.
Methods:
A focused library of 245 compounds, comprising pharmacopeial derivatives and chemogenomic molecules, was screened using a hierarchical virtual screening workflow. Top-ranked hits were further evaluated by rescoring for thermodynamic affinity. The most promising candidate was subjected to a 100 ns molecular dynamics (MD) simulation to assess binding stability, followed by Well-Tempered Metadynamics (WTMetaD) to characterise the free energy landscape and binding behaviour. Pharmacokinetic and toxicity profiles were predicted using SwissADME and ProTox 3.0.
Results:
Three compounds, daunorubicin, doxorubicin, and EUB0000226b, emerged as potential carbapenemase inhibitors. EUB0000226b demonstrated the most favourable binding affinity and structural novelty. MD simulations showed protein stability, while ligand RMSD fluctuations (2.4–5.6 Å) suggested flexible binding. WTMetaD analysis revealed a solvent-separated metastable state that increased ligand residence time within the active site. ADME and toxicity predictions indicated acceptable drug-likeness, good gastrointestinal absorption, and a generally safe profile.
Conclusions:
Multiscale computational analysis identified EUB0000226b as a promising non-covalent carbapenemase inhibitor with favourable binding energetics, dynamic stability, and drug-like properties. These findings support its further experimental validation and potential development for combating carbapenem-resistant bacterial pathogens.

Immunotherapy has transformed oncology, yet has only been marginally effective in prostate cancer (PCa), which is a malignancy with a low mutational load and a highly immunosuppressive tumor microenvironment (TME). This critical review is a reflection on the changing position of the innovative immunotherapies in PCa that extends beyond the description stage to synthesize the synergies and constraints of immune checkpoint inhibitors (ICIs), chimeric antigen receptor (CAR) T-cell therapy, and next-generation modalities such as bispecific T-cell engagers (BiTEs). We assess the mechanistic reasoning of combination therapies, comprising androgen receptor signaling communicators, PARP communicators, and radioligand therapies, which seek to modulate the immunogenicity of the immune-cold PCa TME. Also, we combine new knowledge to novel resistance pathways, including the newly discovered thrombospondin-1-CD47 axis, in the process of T cell exhaustion through calcineurin-NFAT signaling. Although some preclinical data and initial clinical indicators in biomarker-selected subpopulations are promising, the vast majority of Phase III trials of ICIs in unselected populations with metastatic castration-resistant prostate cancer (mCRPC) have failed. This review reveals that the next generation of PCa immunotherapy would not be sequential monotherapies but rather rationally designed multimodal combinations guided by profound molecular and immune profiling to overcome inherent resistance mechanisms.

Background:
The root cause of diabetes is dysregulated pathways, including those involving AMP-activated protein kinase (AMPK), GLUT-mediated glucose transport, and the PI3K/AKT pathway. There has been a notable increase in research on phytoconstituents as pathway-specific treatments for diabetes; however, the comprehensiveness of this evidence remains unclear.
Methods:
This systematic review followed PRISMA guidelines and was registered on PROSPERO (CRD420251073083). Databases searched included PubMed, Scopus, Google Scholar, and Europe PMC for experimental studies (in vivo, in vitro, and in silico) published between 2015 and 2024. The final search was conducted in April 2025, and 2025 publications available as “early access” before this date were included. Only English-language studies were included. Animal studies (in vivo) were assessed for risk of bias using the SYRCLE tool, while in vitro studies were evaluated using the ToxRTool, based on test substance characterization, test system description, study design, and data reporting. Narrative synthesis was employed due to the heterogeneity of the data.
Results:
Out of 3,222 articles, 177 articles met the inclusion criteria. Study types included in vitro (92; 52%), in vivo (66; 37.3%), in silico (15; 8.5%), and other experimental types (4; 2.3%). Phytoconstituents predominantly targeted PI3K/AKT (44.6%), GLUT transporters (19.8%), and AMPK (14.1%) pathways. Rodent models were most used (48.02%). Primary outcomes included improved insulin sensitivity, enhanced glucose homeostasis, and reduced oxidative stress and inflammation. The risk of bias analysis revealed 68.93% of the studies carried a moderate risk, 29.94% a low risk, and 1.13% a high risk.
Discussion:
Phytoconstituent activity was consistent with the activation of diabetes-relevant signaling pathways, particularly PI3K/AKT, GLUT transporters, and AMPK cascades. However, most evidence was correlative, with limited loss-of-function validation. Methodological irregularities, moderate risk of bias, and limited translational research reduce the strength and generalizability of these findings.

Aim:
This study aimed to establish the in vitro efficacy of chlorhexidine (CHX)-silver nanoparticles (AgNP) based preparation, against Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) in planktonic cultures, biofilms, and on inert stainless-steel surfaces.
Methods:
The in vitro antimicrobial activity of the CHX-AgNP formulation (Dermosedan MRSA Nano AG®) was evaluated against reference and multidrug-resistant (MDR) strains of S. aureus and P. aeruginosa by determining the minimum inhibitory and bactericidal concentrations (MIC and MBC), as well as the minimum biofilm inhibitory and eradication concentrations (MBIC and MBEC). Also, the residual bactericidal activity on inert stainless-steel surfaces was evaluated.
Results:
MIC against methicillin-resistant S. aureus (MRSA) and MDR P. aeruginosa (MDR-PA) isolates ranged between 5/2.5–20/10 µg/mL, up to 8,000 times lower than the manufacturer’s recommended concentration, while MBC ranged from 500 to 2,000 times lower. MBIC matched the MBC, while higher concentrations were needed to eradicate preformed biofilms. On stainless-steel surfaces, high antimicrobial activity was observed for both pathogens. No bacterial survival was detected even after 6 hours at 4% CHX + 2% AgNP concentration. The CHX-AgNP combination demonstrated strong antimicrobial and antibiofilm activity against both S. aureus and P. aeruginosa.
Conclusions:
These results support the potential application of Dermosedan MRSA Nano AG® as a strategy for managing topical resistant infections and for environmental disinfection in both veterinary and clinical settings.

Aim:
One of the causes of Alzheimer’s disease (AD) is the structural change and aggregation of target proteins due to the binding of metal ions. In this study, we investigated where copper(II) ions bound to the protein egg white lysozyme crystals in a hydrophilic buffer solution after ions were synthesized from an amino acid Schiff base copper(II) complex with a hydrophobic azobenzene group.
Methods:
X-ray crystallographic studies of the complexes and egg white lysozyme were then studied. Molecular docking studies for the binding of copper(II) ion with egg white lysozyme were also carried out.
Results:
The results suggest that the hydrophobicity of the introduced complex affected how deeply the resultant copper(II) ion penetrated into the protein. It has been revealed that when metal complexes are soaked into protein crystals, the metal complexes act as carriers, and metal ions tend to dissociate and bind to appropriate functional groups on certain specific residues of the protein. His15 and Glu35 were the more common binding residues of the protein that bound to the metal ion.
Conclusions:
An anti-Irving-Williams behaviour was observed for the interaction of the copper(II) complex with the lysozyme. Docking studies revealed various potential binding sites of copper(II) ion with the lysozyme.

Aim:
Diabetes mellitus is a serious public health problem, and the condition is managed using herbal medicine by many African traditional healers. This study aimed to provide scientific evidence on the effects of aqueous and ethanol extracts of Xymalos monospora (X. monospora) leaves on some biochemical parameters in diabetic rats.
Methods:
This experiment included 63 male Wistar rats. Diabetes was induced for 10 days by intraperitoneal injection of dexamethasone (16 mg/kg) in overnight fasted rats. The diabetic rats were treated with aqueous (100 and 200 mg/kg) and ethanol (100 and 200 mg/kg) extracts of X. monospora leaves and metformin (40 mg/kg) for 15 days. Fasting blood glucose, serum lipid profile, atherogenicity indices (Castelli’s Risk Index, Atherogenic Coefficient, Atherogenic Index of Plasma), tumor necrosis factor alpha, and hepatic glycogen were evaluated.
Results:
Treatment with the aqueous extracts at 100 and 200 mg/kg significantly reduced fasting blood glucose by 29.2% (p = 0.016) and 35.9% (p = 0.009), respectively. Also, the ethanol extracts at 100 and 200 mg/kg significantly reduced fasting blood glucose by 20.7% (p = 0.038) and 31.2% (p = 0.027), respectively. The aqueous extract (200 mg/kg) significantly reduced total cholesterol and triglyceride concentrations by 31.5% (p = 0.017) and 30.7% (p = 0.023), respectively. There was a significant reduction in atherogenicity indices (p < 0.05), and liver glycogen levels improved. The extracts reduced the levels of tumor necrosis factor alpha, but this was not significant (p > 0.05). However, histopathological studies were not carried out, and the above findings may not directly translate to clinical efficacy.
Conclusions:
These findings demonstrate that the oral administration of aqueous and ethanol extracts of X. monospora leaves has significant antidiabetic effects, including a decrease in fasting blood glucose, improvement of serum lipid profile, and increased glycogen storage.

Antimicrobial peptides (AMPs) are a heterogeneous group of small, naturally occurring molecules that are an integral part of the innate immunity of nearly all life forms. Their amphiphilic nature, cationic character, and small size distinguish AMPs, which have a wide spectrum antimicrobial activity against bacteria, fungi, parasites, and viruses. Their specific ability to selectively destroy microbial membranes, without harming host cells, makes them promising contenders to treat the growing threat of antimicrobial resistance (AMR), which has undermined the effectiveness of traditional antibiotics. The action mechanisms of AMPs are multifaceted, involving both membrane-disruptive mechanisms, like barrel stave pore formation, toroidal pore induction, and carpet-like membrane degradation, and non-membrane targeting mechanisms, like inhibition of nucleic acid synthesis, protein translation, and cell wall biosynthesis. AMPs are structurally diverse, from α-helices and β-sheets to cyclic and unstructured peptides, and are distributed abundantly in nature, being derived from mammals, amphibians, insects, plants, and microorganisms. Apart from antimicrobial activity, AMPs have immunomodulatory and regenerative activities, enabling their use in many therapeutic and industrial applications. These are for the construction of new anti-infective agents, wound healing compounds, medical device coatings to inhibit biofilm growth, natural food preservatives, adjuvants for vaccines, and possible anti-cancer drugs. Although they hold great promise, stability, toxicity, and production scale issues continue to hinder translation to the clinic. This review highlights the structural variability, modes of action, and novel uses of AMPs, with a focus on their status as next-generation therapeutics against multidrug-resistant microbes and for promoting biomedical innovation.

Buarque et al. (Explor Drug Sci. 2025;3:1008107. DOI: 10.37349/eds.2025.1008107) reported the synthesis of 13 biaryl hydroxy-1,2,3-triazoles and 11 fluorene-1,2,3-triazole hybrids via optimized Suzuki and telescopic one-pot reactions. Cytotoxicity evaluations against colorectal cancer (HCT-116), astrocytoma (SNB-19), triple-negative breast cancer (MDA-MB-231), and acute myeloid leukemia, FLT3-ITD mutant (MOLM-13) cell lines revealed promising antitumor activity. 1-(2-bromophenyl)-4-(9H-filoren-9-yl)-1H-1,2,3-triazole (LSO258) and 1-(4-bromophenyl)-4-(2-fluoro-9H-fluron-9-yl)-1H-1,2,3-triazole (LSO272), both being fluorene-1,2,3-triazole hybrids with bromine substituents, could selectively inhibit the activity of MOLM-13 cells, while the biaryl hydroxy-1,2,3-triazoles compounds exhibited broader antitumor activity. It is worth noting that an inevitable phenomenon is observed: The above compounds have significant aromatic structural characteristics, and their large aromatic systems lead to increased molecular hydrophobicity, resulting in poor water solubility. This critical druggability limitation will directly restrict the development of formulations. To tackle this issue, this paper proposes micelles as the optimal solution. As a carrier structure formed by the self-assembly of amphiphilic surfactants, micelles possess a unique “hydrophobic core-hydrophilic shell” configuration. Their hydrophobic core layer can efficiently encapsulate triazole compounds containing aromatic structures. Compared to other nanomedicine formulations such as solid dispersions and nanoencapsulation technology, micelles demonstrate significant advantages in terms of stability, process simplicity, and biocompatibility.

The escalating threat of antibiotic resistance and its advancing mechanisms for resistance development underscore the imperative need for alternative approaches to treat life-threatening infections. Consideration of bacteriophages, as well as antimicrobial peptides (AMPs) that can specifically target and eliminate particular bacteria, is gaining prominence for the improved treatment of infections. The effectiveness of bacteriophages and AMPs has been known for a long time, and their combined use is being investigated recently. Studies have shown that the use of phages or phage-derived enzymes (endolysins) in combination with AMPs has shown promising results in combating multidrug resistant bacteria. Bacteriophages lyse bacteria by hijacking the bacterial cell’s metabolic machinery, leading to the production of phage virus inside it and finally bursting the bacteria, while AMPs act by disrupting the bacterial cell membrane or affecting intracellular targets after penetration. In this review, we discuss previous studies on the combined use of both phages or phage-derived enzymes and AMPs, demonstrating their synergistic effects for combating multidrug resistant pathogens. Their mechanisms of action, and possible mechanisms of synergy and development of bacterial resistance to these, are discussed. Approaches, including genetic engineering, for improving their efficacy have been discussed. Safety and ethical issues regarding their use in human subjects are discussed. In summary, this review emphasizes the need for further research on the combined use of AMPs and bacteriophages to tap their potential effectiveness for treating antimicrobial-resistant infections.
The escalating threat of antibiotic resistance and its advancing mechanisms for resistance development underscore the imperative need for alternative approaches to treat life-threatening infections. Consideration of bacteriophages, as well as antimicrobial peptides (AMPs) that can specifically target and eliminate particular bacteria, is gaining prominence for the improved treatment of infections. The effectiveness of bacteriophages and AMPs has been known for a long time, and their combined use is being investigated recently. Studies have shown that the use of phages or phage-derived enzymes (endolysins) in combination with AMPs has shown promising results in combating multidrug resistant bacteria. Bacteriophages lyse bacteria by hijacking the bacterial cell’s metabolic machinery, leading to the production of phage virus inside it and finally bursting the bacteria, while AMPs act by disrupting the bacterial cell membrane or affecting intracellular targets after penetration. In this review, we discuss previous studies on the combined use of both phages or phage-derived enzymes and AMPs, demonstrating their synergistic effects for combating multidrug resistant pathogens. Their mechanisms of action, and possible mechanisms of synergy and development of bacterial resistance to these, are discussed. Approaches, including genetic engineering, for improving their efficacy have been discussed. Safety and ethical issues regarding their use in human subjects are discussed. In summary, this review emphasizes the need for further research on the combined use of AMPs and bacteriophages to tap their potential effectiveness for treating antimicrobial-resistant infections.

Metabolic dysfunction-associated steatohepatitis (MASH) is emerging as a leading cause of cirrhosis, hepatocellular carcinoma, and liver-related mortality worldwide. Among the most advanced pharmacologic candidates are resmetirom, a highly liver-selective thyroid hormone receptor-β (THR-β) agonist, and semaglutide, a long-acting glucagon-like peptide-1 receptor agonist (GLP-1 RA) already approved for diabetes and obesity. Although both agents improve hepatic steatosis, their mechanisms of action, extra-hepatic benefits, and safety signatures diverge markedly. Resmetirom, which was approved by the Food and Drug Administration (FDA) in March 2024, acts hepatocentrically to accelerate β-oxidation, lower atherogenic lipoproteins, and deliver early signals necessary for fibrosis regression, all while largely avoiding systemic thyrotoxic effects. Semaglutide acts systemically by reducing caloric load through pronounced weight loss and glycemic control, producing the highest rates of histologic MASH resolution reported to date, albeit with less direct antifibrotic efficacy and characteristic gastrointestinal tolerability issues. This comparative perspective juxtaposes the two compounds with respect to molecular pharmacology, clinical efficacy, safety, and potential clinical positioning, and proposes that, because resmetirom primarily targets hepatic lipid disposal whereas semaglutide unloads systemic caloric pressure, their complementary actions could be harnessed sequentially or in combination to achieve broader, more durable disease modification across the heterogeneous spectrum of patients with MASH.

Cedarwood essential oil (CWO), obtained from Cedrus and related species, has a long history in traditional medicine but remains relatively underexplored in modern pharmacology. This review consolidates current evidence on its phytochemical composition and pharmacological activities. Literature was retrieved from PubMed, Web of Science, and Scopus up to July 2025, including in vitro, in vivo, and limited clinical studies. Findings suggest antimicrobial, anti-inflammatory, sedative, and dermatological properties, primarily attributed to sesquiterpenes such as cedrol and α-cedrene. However, most data derive from small-scale or preclinical studies, with limited standardization of dosage and formulations. Safety aspects and toxicological gaps are also highlighted as essential considerations for future clinical translation. We conclude that CWO shows therapeutic potential, but rigorous clinical trials, standardized protocols, and comprehensive toxicological evaluations are essential before its safe and effective integration into evidence-based practice.

Probiotics, originating at birth, play a crucial role in the development and maintenance of a healthy and disease-free environment within the gut of both humans and animals. These beneficial microorganisms from fermented, processed, and non-dairy foods provide numerous health benefits, such as stress reduction, disease prevention, immune stimulation, gut microbiota control, nutritional supplementation, diarrheal disease relief, vitamin production, weight management, and anticancer activities. With more health problems on the rise and the negative side effects of conventional medication and antibiotics prevailing, natural supplements such as probiotics are a relief. Probiotics, such as Lactobacillus, Bifidobacterium, and Saccharomyces, have been identified as safe and effective candidates for gut health applications. This review addresses the current understanding of the mechanism of action of probiotics, their functions in human health, and their therapeutic potential for various diseases. We emphasize the importance of prioritizing probiotic administration along with conventional medicinal drugs for their wide benefits and fewer side effects. Our findings aim to direct future studies on the modes of action of probiotics against emerging health challenges.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more rapidly progressive variant steatohepatitis (MASH) are widespread chronic liver conditions linked to obesity and other common metabolic disorders. The emergence of tirzepatide, a dual incretin receptor agonist targeting both the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, presents major therapeutic potential for MASLD. This review article explores the mechanisms of action of tirzepatide, highlighting its ability to improve glycemic control, promote weight loss, and potentially ameliorate hepatic steatosis and fibrosis. Recent studies suggest that tirzepatide may offer significant benefits in managing MASLD/MASH by modulating metabolic pathways and enhancing liver health. However, further research is needed to fully understand its long-term impact on MASLD/MASH progression and outcomes across diverse patient populations.

Aim:
Menopausal women are suffering from stress-related disorders, and in the previous studies, Khaya anthotheca (K. anthotheca) decoction exhibited estrogenic and anxiolytic properties. Taken together, the aim of this study was to evaluate the effects of K. anthotheca decoction on behavioral disorders and oxidative stress induced by repeated variable stress in ovariectomized Wistar rats.
Methods:
Forty-two female Wistar rats (10–12 weeks old; 145 ± 10 g) were used. They were ovariectomized (except those from the sham operated group). Fourteen days after ovariectomy, animals were randomly distributed into 7 groups (n = 6): sham operated and negative control groups receiving distilled water; two positive control groups receiving estradiol valerate and diazepam (1 mg/kg each), and three other groups receiving the tested doses of K. anthotheca extract (125, 250, and 500 mg/kg each). The treatment was applied every week. Anxiety, depression, and motor coordination were assessed throughout the experimental procedure. The anti-oxidative potential of the extract was evaluated in rat brain homogenate.
Results:
It was noted that K. anthotheca extract induced anxiolytic effects marked by an increase in the locomotory activity during open field, light/dark, and elevated plus maze tests. Besides, its anti-depressive effects were shown by a significant (p < 0.05) decrease in the immobilization time during the forced swimming test. By improving the suspension time during grid and wire grip tests, the distance covered, and the number of switch directions during the beam walking test, the extract increased motor coordination. The antioxidant potential of the extract was marked by a significant decrease (p < 0.01) in malondialdehyde level and an increase (p < 0.05) in reduced glutathione level.
Conclusions:
These results provide valuable insights into the potential therapeutic application of the K. anthotheca extract; however, more studies are needed to elucidate mechanisms of action.

Nanotechnology is a relatively young field of science that has found wide application in medicine, especially in oncology. It focuses on studying molecules at the atomic, molecular, and supramolecular levels, enabling the development of innovative therapeutic solutions. Thanks to research in this field, it has become possible to introduce nanoparticles (NPs) into therapy, specially designed molecules that release the drug in a precisely defined place. This approach allows for maintaining the appropriate therapeutic concentration of the drug substance in the body for a longer period of time. The use of NPs in the treatment of cancer diseases helps to overcome the limitations of traditional chemotherapy, such as systemic, toxic effects of drugs, lack of specificity towards cancer cells, and limited bioavailability. NPs can be used not only as drug carriers, but also as contrast agents enabling imaging at the molecular level. More accurate visualization of diseased tissues is possible thanks to the small size of NPs, optical properties, and the ability to accumulate in the tumor area. Additionally, the use of specific ligands allows detection of pathological changes at the cellular level, allowing for earlier detection of changes, which in turn increases the probability of complete recovery of the patient.

Cholecystokinin (CCK) is the most prevalent neuropeptide in the brain, where it affects satiety, pain modulation, memory, and anxiety. Its effects are mediated by GPCRs known as the “alimentary (gastrointestinal)” CCK1r (CCK 1 receptor) and the brain-specific CCK2r (CCK 2 receptor). While stress causes CCK to be released and full CCK2r agonists are potent panicogenic agents, specific CCK2r antagonists are ineffective at lowering human anxiety. As a result, the therapeutic potential of CCK as a target in psychiatry has been questioned. By compiling relevant new and historical scientific data retrieved from Scopus and PubMed, the aim of this review was to suggest a new function of CCK neurotransmission, the regulation of neuronal homeostasis during stress. Four lines of evidence were discussed that support the hypothesis of a CCK-driven neuronal homoestasis: (1) Homeostatic plasticity including synaptic scaling and intrinsic excitability; (2) its interaction with retrograde endocannabinoid signaling; (3) neuroprotective role; and (4) dynamic neuromodulation of CCK release. CCK functions as a crucial and essential molecular switch of neural circuits and neuroplasticity through its remarkable cell-specific modulation of glutamate and GABA release via CCK2r. CCKergic neurons are downstream of the activation of cannabinoid type-1 (CB1) receptors in order to generate and stabilize rhythmic synchronous network activity in the hippocampus. CCK is also released to modulate other neurotransmitters like dopamine and opioids when neuronal firing is intense during the processing of anxiety/fear, memory, and pain. CCK likely functions to restore baseline neuronal function and protect neurons from harm under these conditions. Anxiety, depression, and schizophrenia could result from compensatory plastic changes of the CCKergic system that go awry during neuronal homeostasis. This review concludes by examining the benefits of putative compounds that exhibit a combination of CCK agonist and antagonist activity at multiple locations within the CCKergic system, as well as off-targets in managing mental conditions.
