Lactiplantibacillus plantarum fermented hemp (Cannabis sativa) seeds modulate the gut microbiota and metabolic pathways to alleviate autoimmune inflammation in collagen-induced arthritis mice

. FHS also influenced key metabolites, such as short-chain fatty acids, stearic acid, oleic acid, taurine, palmitic acid, docosahexaenoic acid, linoleic acid, and L-tyrosine, impacting metabolic pathways linked to RA progression. Notably, indolelactic acid, homovanillic acid, and bioactive peptides in FHS were absorbed into the bloodstream, exerting direct anti-inflammatory effects. These findings underscore FHS's potential as a therapeutic functional ingredient for RA, offering insights into its mechanisms through gut microbiota modulation and metabolic regulation.
