1 RESULTS: When added at day 0, calcitriol blocked DC differentiation from monocytes and inhibited the generation of CD1a(+) cells from progenitor cells while increasing CD14(+) cells. Calcitriol CD1a molecule Homo sapiens
2 Exposure of immature DCs to calcitriol at day 6 resulted in a loss of the DC-characteristic surface molecule CD1a, downregulation of the costimulatory molecules CD40 and CD80, and MHC class II expression, whereas the monocyte/macrophage marker CD14 was clearly reinduced. Calcitriol CD1a molecule Homo sapiens
3 In contrast, the mature CD83(+) DCs remained CD1a(+)CD14(-) when exposed to calcitriol. Calcitriol CD1a molecule Homo sapiens
