Effect of dysbiosis on proportion of particular neutrophil subsets and their functional capacities
Sklenářová, Lydie ; Hrdý, Jiří (advisor) ; Dobeš, Jan (referee)
The gut microbiota is crucial for maintaining physiological balance and influences metabolic processes, immune responses, and intestinal barrier function. Dysbiosis, or the imbalance of microbial composition, is associated with a range of health complications, including chronic inflammatory conditions such as non-specific intestinal inflammations. Inflammatory processes associated with dysbiosis and changes in microbial metabolites can directly affect the activation of neutrophils, impacting the pathogenesis of various diseases. Probiotics, defined as live microorganisms which, when administered in adequate amounts, confer a health benefit on the host, offer the potential for positive modulation of these inflammatory conditions The aim of this thesis was to explore how experimentally induced intestinal dysbiosis affects the heterogeneity of neutrophils in the bone marrow. Dysbiosis was induced by administering antibiotics to mice, which were subsequently treated with the probiotic strain Escherichia coli O83:K24:H31 (EcO83). Neutrophil phenotypes were assessed using flow cytometry based on the expression of surface markers CD11b, Ly6G, CD62L, and CXCR2. Meanwhile, gene expression related to their antimicrobial functions and the inflammatory environment was analyzed by quantitative PCR. The results...
