A healthy mucus is essential for maintaining intestinal homeostasis and overall well-being. In recent years, extensive research focused on understanding the intricate interactions between mucus and the gut microbiota. Mucus-adhering bacteria play crucial roles in preserving barrier integrity, epithelial permeability and mucus architecture, as well as in the colonization resistance against pathogens. Unravelling the significance of these microorganisms in human health and disease is challenging, primarily because most of the studies on the human gut microbiota rely on faecal samples, which do not fully represent the microecological complexity found in the intestinal mucosa. This review discusses novel strategies to specifically target and evaluate the mucosal microbiota, such as culturomics applied to mucosal biopsies or brushings, intestinal organoids and artificial in vitro models incorporating mucus.

The biotransformation of drugs by enzymes from the human microbiome can produce active or inactive products, impacting the bioactivity and function of these drugs inside the human host. However, understanding the biotransformation reactions of drug molecules catalyzed by bacterial enzymes in human microbiota is still limited. Hence, to characterize drug utilization capabilities across all the microbial phyla inside the human gut, we have used a knowledge-based approach to develop HgutMgene-Miner software which predicts xenobiotic metabolizing enzymes (XMEs) through genome mining.

2-Amino-3-methylimidazole [4,5-] quinoline (IQ) is a kind of heterocyclic amine (HCAs) with high carcinogenicity in hot processed meat. Rutin (Ru) is a flavonoid compound with anti-inflammatory and antioxidant properties. However, whether Ru is scatheless under IQ-stimulated potential unhealthy conditions, especially liver function, in vivo, is unknown.

Backgrounds: Memory and emotion are especially vulnerable to psychiatric disorders such as post-traumatic stress disorder (PTSD), which is linked to disruptions in serotonin (5-HT) metabolism. Over 90% of the 5-HT precursor tryptophan (Trp) is metabolized via the Trp-kynurenine (KYN) metabolic pathway, which generates a variety of bioactive molecules. Dysregulation of KYN metabolism, particularly low levels of kynurenic acid (KYNA), appears to be linked to neuropsychiatric disorders.

Multiple sclerosis (MS) is a chronic autoimmune disorder marked by neuroinflammation, demyelination, and neuronal damage. Recent advancements highlight a novel interaction between iron-dependent cell death, known as ferroptosis, and gut microbiota, which may significantly influences the pathophysiology of MS. Ferroptosis, driven by lipid peroxidation and tightly linked to iron metabolism, is a pivotal contributor to the oxidative stress observed in MS.

Alzheimer's disease (AD) is a common central neurodegenerative disease disorder characterized primarily by cognitive impairment and non-cognitive neuropsychiatric symptoms that significantly impact patients' daily lives and behavioral functioning. The pathogenesis of AD remains unclear and current Western medicines treatment are purely symptomatic, with a singular pathway, limited efficacy, and substantial toxicity and side effects. In recent years, as research into AD has deepened, there has been a gradual increase in the exploration and application of medicinal plants for the treatment of AD.
