WebNov 20, 2024 · IRF7 has also been implicated in the pathogenesis of type 1 diabetes through the upregulation of inflammatory gene networks ( 50 ). Most relevant to the current review is the finding that reduction/inhibition of mucosal IRF7 expression with liposomal Irf7 siRNA resulted in protection of mice from bacterial infection and renal tissue damage ( 51 ). WebApr 17, 2015 · The NF-κB and IRF transcription factor families are major players in inflammation and antiviral response and act as two major effectors of the innate immune response (IIR).
