STING controls mucosal Th17 immunity for host defenses against microbial DNA in gut

Microbial DNA binds to host intracellular protein-STING encoded by Tmem173. In this study, we demonstrate that STING
triggers adaptive immune responses that control Th17 differentiation. Microbial DNA recognition enables Classical
Dendritic Cells (CDCs) that predominantly express CD103 to induce Th17 lymphocytes in an IL-6/IL-1β-dependent manner
in gut. STING expression in human lamina propria is associated with the severity of mucosal inflammation and clinical disease
activity in patients with Crohn’s disease. Mice deficient in Tmem173 fail to mount Th17 responses or prevent immune evasion
of enteroinvasive pathogens. In summary, STING in mucosal cDCs controls Th17 sub specification that is essential for host
defenses against microbial infection in gut-associated immune system.
