Omega-3 polyunsaturated fatty acids are associated with microbiota-related 18β-glycyrrhetinic acid alterations and M2 macrophage polarization in type 1 diabetes mellitus

IntroductionOmega-3 polyunsaturated fatty acids (PUFAs) have been widely reported to exert beneficial effects in type 1 diabetes mellitus (T1DM). However, the mechanisms by which Omega-3 PUFAs influence pancreatic islet function through the gut-islet axis remain incompletely understood. This study aimed to investigate whether Omega-3 PUFAs-associated alterations in gut microbiota composition and their metabolites are involved in the modulation of the pancreatic islet microenvironment in T1DM, an
