CD79A and infection: Despite participating in maintaining intestinal homeostatic balance, SFB-induced homeostatic Th17 cells fail to secrete IFN-γ following stimulation and could not eliminate C. rodentium-elicited infection.259 Notably, SFB also exert impacts on numerous additional aspects of the immune system by facilitating the development of intestinal lymphoid tissue and mediating IgA responses.274 Consequently, SFB potentially influences multiple immunomodulatory responses via a common pathway.
