HCV patients after treatment exhibit high frequency of monocytes, myeloid dendritic cells, plasmacytoid dendritic cells, CD4+ T cells, and NKT cells (Figure 1(a)), together with a high concentration of CXCL-8, CXCL-9, and CXCL-10 chemokines and IL-6, IL-10, and IL17A modulated/proinflammatory cytokine pattern when compared to the HD group (Figure 1(b)), while NK cells, CD8+ T cells, and T reg cell serum concentrations decreased after the end of treatment when compared to the HD group (Figure 1(a)). The gene discussed is IL17A; the disease is Huntington disease.
