Neurodegeneration is characterized by a disturbance in neurotransmitter-mediated signaling pathways. Recent studies have highlighted the significant role of transition metal ions, including Cu(i/ii), Zn(ii), and Fe(ii/iii), neurotransmission, thereby making coordination chemistry neurotransmitters growing field interest understanding signal dysfunction. This review outlines physiological functions ions neurotransmitters, with metal-binding properties small molecule-based neuropeptides. Additionally, we discuss structural conformational changes induced redox-active such as Cu(i/ii) briefly describe outcomes arising from their oxidation, polymerization, aggregation. These observations important implications for neurodegeneration emphasize need further research to develop potential therapeutic strategies.

This review synthesizes the evidence on associations between antidepressant use and gut microbiota composition function, exploring microbiota's possible role in modulating treatment outcomes. Antidepressants exert an influence measures of microbial diversity. The most consistently reported differences were β-diversity those exposed to antidepressants not exposed, with longitudinal studies supporting a potential causal association. Compositional alterations users include increase Bacteroidetes phylum, Christensenellaceae family, Bacteroides Clostridium genera, while decrease was found Firmicutes Ruminococcaceae Ruminococcus genus. In addition, attenuate depressed healthy individuals, modulate serotonin transport, metabolic functions. These lyxose degradation, peptidoglycan maturation, membrane methylerythritol phosphate pathways, alongside gamma-aminobutyric acid metabolism. Importantly, baseline increased α-diversity abundance Roseburia Faecalibacterium are associated response, emerging as promising biomarkers. highlights for predictor response emphasizes need further research elucidate mechanisms underlying antidepressant-microbiota interactions. More homogeneous standardized techniques required confirm these initial findings.

While most research has focused on therapeutic effects of in treatment various diseases, recent years seen a shift towards exploring role enhancing and supporting overall health. Methods: In this work, we studied novel potential probiotic strain, Lactiplantibacillus pentosus PE11, healthy mice following six-week dietary intervention. The assessment included monitoring general animals, biochemical analyses, profiling gut fecal microbial communities, gene expression analysis.

Inflammatory Bowel Disease (IBD) is a chronic gastrointestinal disorder characterized by periods of activity and remission. IBD includes Crohn’s disease (CD) ulcerative colitis (UC), even though has not been considered as heritable disease, there are genetic variants associated with increased risk for the disease. 5-Hydroxytriptamine (5-HT), or serotonin, exerts wide range effects under both normal pathological conditions. Furthermore, Serotonin Transporter (SERT) coded Solute Carrier Family 6 Member 4 (SLC6A4) gene (located in 17q11.1-q12 chromosome), possesses variants, such Gene Variable Number Tandem Repeat Intron 2 (STin2-VNTR) Serotonin-Transporter-linked promoter region (5-HTTLPR), which have an influence over functionality SERT re-uptake bioavailability serotonin.
