(GALT) is responsible for distinguishing pathogenic organisms from harmless food proteins and commensal bacteria. Antigens sampled across the intestinal epithelium are presented by CD103⁺ dendritic cells, which migrate to mesenteric lymph nodes and promote differentiation of Foxp3⁺ regulatory T cells (Tregs). These Tregs subsequently return to the intestinal lamina propria, where cytokines such as interleukin-10
