Abstract: Especially,
PB2-
I283M-
K526R mutation strongly induced a sharp expression of cytokine storm-related genes, including MX1, CXCL10, and IFN-gamma, performed by qRT-PCR.
Abstract: Here, RNA-seq method was used to analyze the global host response of murine lungs after infecting with parental r-JY virus and JY-
PB2-
I283M-
K526R mutant virus.
Abstract: Taken together, our data demonstrated that
PB2-
I283M-
K526R of H5N8 subtype HPAIV exacerbated the innate immune response and the level of cell apoptosis, which might be a key pathogenic mechanism for the enhanced pathogenicity of mutants in mammals.
