Popis: NLRC5 is a member of the NOD-Like receptor family and reportedly functions in the regulation of type I interferons and inflammasome activation. In addition, NLRC5 functions as a transcriptional transactivator of MHC-I gene expression. We have observed that Nlrc5-deficient mice infected with influenza A virus have normal type I interferon responses and inflammasome activation but have dramatically reduced H-2Db and H-2Kb major histocompatibility complex (MHC)-I allele expression on virtually all myeloid and lymphoid cells. Furthermore, Nlrc5-/- mice have diminished capacity for CD8+ T cell responses directed toward influenza A virus following infection. These data suggest that during influenza A virus infection, NLRC5 plays an important function in the generation of adaptive immunity but has no detectable role in the innate immune response.
