Abstract: Research of function of vitamin D on immune system has been studying since the study revealed that vitamin D receptor is expressed on the surface of the immune cells. 1,2-dihydroxyvitamin D3 [1,25(OH)2D], physiologically active form, can be generated through hydroxylation of 25-hydroxyvitamin D3 [25(OH)D], inactive form of vitamin D, in a liver, connecting with specific VDR make biological action. Vitamin D make different biological actions depends on connecting with different immunological cells. Some studies indicated that Vitamin D plays pivotal role in antibacterial innate immune responses through regulating reaction of the main cells as macrophages and dendritic cells. Moreover, calcitriol, the active form of vitamin D, is connected with VDRE, modulates the innate immune response through directly inducing expression of catelicithin and β-defensin as antimicrobial peptides, reducing secretion of IL-1b, IL-6, TNF-a, RANKL, COX-2 as proinflammatory cytokines and increasing production of IL-10, an anti-inflammatory cytokine. Vitamin D plays in proliferation and differentiation of T and B cells and regulates the activities of over 500 genes. Vitamin D differently impacts on per se stages of T cells’ proliferation. Vitamin D indirectly mitigates the differentiation from immature B cells to plasma B cells while it directly impacts on regulation of overloaded production of antibodies in plasma B cells. In conclusion, vitamin D modulates the innate- and adaptive immune response through regulation on activation of APCells, proliferation and differentiation of immune cells, secretion of some antibacterial peptides.
