IFNG and cryohydrocytosis: To assess the potential role of different subsets of T cells, especially Th cell subsets, in type III asymptomatic MC with HCV infection, total T cells, CD4+ T cells, and CD4+ T cell subsets, including Th1 cells (IFN-γ + CD4+ T cells), Th2 cells, Th17 cells, Th22 cells, and Treg cells (CD4 + CD25 + Foxp3+ cells) were analyzed in CHC patients, HCV-related MC patients, and HCs.
