Many studies have shown that Akkermansia can effectively improve symptoms in mouse models of diseases such as ALS [34], progeria [35], and chronic colitis [36] by promoting healing and recovery of intestinal mucosal layer and reducing the expression of proinflammatory cytokines such as TNF-α and interferon gamma (IFN-γ) in the colon. This evidence concerns the gene IFNG and amyotrophic lateral sclerosis.
