IL17A and infection: However, the accumulation of neutrophils after Poly I:C injection was less significant than those with Listeria monocytoegnes infection, and the Ly6G+CD11b+ cells in the liver was not affected by IL-17A neutralization (Figure S3), indicating that the attenuation of Poly I:C-induced acute hepatitis by IL-17A neutralization was not caused by the reduction of neutrophil recruitment in the liver.
