1 Vitamin D Counteracts Mycobacterium tuberculosis-Induced Cathelicidin Downregulation in Dendritic Cells and Allows Th1 Differentiation and IFNgamma Secretion. Vitamin D interferon gamma Homo sapiens
2 Paradoxically, vitamin D has repeatedly been ascribed an immune-suppressive function inhibiting Th1 differentiation and production of IFNgamma in T cells. Vitamin D interferon gamma Homo sapiens
3 We show that vitamin D does not block differentiation of human CD4+ T cells to Th1 cells and that interleukin (IL)-12 partially counteracts vitamin D-mediated inhibition of IFNgamma production promoting production of equal amounts of IFNgamma in Th1 cells in the presence of vitamin D as in T cells activated in the absence of vitamin D and IL-12. Vitamin D interferon gamma Homo sapiens
4 We show that vitamin D does not block differentiation of human CD4+ T cells to Th1 cells and that interleukin (IL)-12 partially counteracts vitamin D-mediated inhibition of IFNgamma production promoting production of equal amounts of IFNgamma in Th1 cells in the presence of vitamin D as in T cells activated in the absence of vitamin D and IL-12. Vitamin D interferon gamma Homo sapiens
5 We show that vitamin D does not block differentiation of human CD4+ T cells to Th1 cells and that interleukin (IL)-12 partially counteracts vitamin D-mediated inhibition of IFNgamma production promoting production of equal amounts of IFNgamma in Th1 cells in the presence of vitamin D as in T cells activated in the absence of vitamin D and IL-12. Vitamin D interferon gamma Homo sapiens
6 In conclusion, we demonstrate that vitamin D counteracts M. tuberculosis-induced cathelicidin downregulation and allows Th1 differentiation and IFNgamma secretion. Vitamin D interferon gamma Homo sapiens
