Intrigued by the well‐established role of butyrate in suppressing inflammation, stimulating secretion of enteroendocrine hormones35 and conserving beta cell functions in T1DM,36 we measured serum inflammatory cytokines (interleukin [IL]‐1β, IL‐4, IL‐6, IL‐7, IL‐10, IL‐17A, IL‐18, interferon gamma, tumor necrosis factor‐α, and TGF‐β1) (Figure S5), plasma enteroendocrine hormones (GLP‐1, GLP‐2, and PYY) during the SBMT (Figure S6), and serum C‐peptide (Table 1). This evidence concerns the gene IL6 and type 1 diabetes mellitus.
