Also in the hepatic T cell populations, the percentages of IFNγ and IL-17 secretion were increased but since the reduction in the percentages of CD4+ and CD8+ T cells is considerable, the total amount of IFNγ and IL-17 which is produced by T cells throughout the process of hepatic steatosis development was likely lower in Lck-Cre Atg7f/f mice. This evidence concerns the gene CD4 and fatty liver disease.
