Increased evidence shows that gut microbiota acts as the primary regulator of liver; however, its role in sepsis-related liver injury (SLI) elderly is unclear. This study assessed whether metformin could attenuate SLI by modulating septic-aged rats. Cecal ligation and puncture (CLP) was used to induce aged Fecal transplantation (FMT) validate roles these pathologies. The composition analysed 16S rRNA sequencing. Moreover, colon tissues were histopathology, immunofluorescence, immunohistochemistry, reverse transcription polymerase chain reaction (RT-PCR). Metformin improved damage, barrier dysfunction sepsis-induced inflammation damage under microbiota. Importantly, FMT assay showed rats gavaged with faeces from metformin-treated displayed less severe dysfunctions than those among sham-operated, CLP-operated different. In particular, proportion Klebsiella Escherichia_Shigella higher sham-operated rats; while increase Bifidobacterium, Muribaculaceae, Parabacteroides_distasonis Alloprevitella Additionally, correlated positively inflammatory factors liver. Our findings suggest may improve regulating alleviating rats, which be an effective therapy for SLI.

Liver fibrosis due to viral or metabolic chronic liver diseases is a major challenge of global health. Correlating with disease progression, key factor for outcome and risk hepatocellular carcinoma (HCC). Despite different mechanism primary injury disease-specific cell responses, the progression fibrotic follows shared patterns across main etiologies. Scientific discoveries within last decade have transformed understanding mechanisms fibrosis. Removal elimination causative agent such as control cure infection has shown that reversible. However, reversal often occurs too slowly infrequent avoid life-threatening complications particularly in advanced Thus, there huge unmet medical need anti-fibrotic therapies prevent HCC development. while many candidate agents robust effects experimental animal models, their clinical trials been limited absent. no approved therapy exists In this review we summarize cellular drivers molecular fibrogenesis discuss impact development urgently needed therapies.

The intestinal mucosa provides a selective permeable barrier for nutrient absorption and protection from external factors. It consists of epithelial cells, immune cells their secretions. gut microbiota participates in regulating the integrity function homeostatic balance. Pathogens, xenobiotics food can disrupt barrier, promoting systemic inflammation tissue damage. Genetic factors predispose individuals to dysfunction, changes composition are central this process. progressive identification these has led development concept ‘leaky syndrome’ ‘gut dysbiosis’, which underlie relationship between impairment, metabolic diseases autoimmunity. Understanding mechanisms underlying process is an intriguing subject research diagnosis treatment various extraintestinal diseases.

Environmental exposure plays a major role in the development of allergic diseases. The exposome can be classified into internal (e.g., aging, hormones, and metabolic processes), specific external chemical pollutants or lifestyle factors), general broader socioeconomic psychological contexts) domains, all which are interrelated. All factors we exposed to, from moment conception to death, part exposome.
