CD4 and breast angiosarcoma: Contrary to previous findings that bile acids selectively modulate Treg and Th17 cell responses (34), there were no correlations between CD4+ T cell ratios (r2 = 0.00, p = 0.93), Treg (r2 = 0.01, p = 0.51), Th1 (r2 = 0.01, p = 0.32), Th2 (r2 = 0.01, p = 0.60), Th17 cells (r2 = 0.03, p = 0.24) and serum total bile acid levels in young children with BA (Figure 3).
