Figure 3. IL-17 production by PBMCs and CD4+ T cells. Cells were cultured with anti-CD3 and anti-CD28 antibodies in the presence or absence of 1,25(OH)2D3 for 72 h. A: IL-17 production by PBMCs from active VHK patients (n=11), inactive VHK patients (n=7) and normal controls (n=12). B: IL-17 production by CD4+ T cells from active VHK patients (n=7), inactive VHK patients (n=7) and normal controls (n=9).
