In the past, vitamin D was known for its classical, skeletal action as a regulator of calcium
and bone homoeostasis. Currently, vitamin D was found to have a role in numerous …

Vitamin D has potential antimicrobial activity, the deficiency of which has deleterious effects
on the general well-being and longevity, predisposing major public health problem …

Vitamin D3 affects both the innate as well as adaptive immune responses. Epidemiological
studies have established that vitamin D3 deficiency plays an important role in tuberculosis …

The primary function of vitamin D is to regulate calcium homeostasis, which is essential for
bone formation and resorption. Although diet is a source of vitamin D, most foods are …

Immune cells, including dendritic cells, macrophages, and T and B cells, express the vitamin
D receptor and 1↵-hydroxylase. In vitro studies have shown that 1, 25-dihydroxyvitamin D …

1, 25-Dihydroxyvitamin D3 (1, 25 (OH) 2D3), the active form of vitamin D3, is a central player
in Ca and bone metabolism. More recently, important immunomodulatory effects have been …

Vitamin D has emerged as a pleiotropic regulator of human physiology, and recent work has
revealed that it has several roles in control of human immune system function. Vitamin D …

Vitamin D plays a role in the synthesis of antibacterial peptids and in autophagy. Several
studies have shown that low levels of vitamin D are associated with the susceptibility and the …

Vitamin D plays a crucial role in modulating the innate immune response by interacting with
its intracellular receptor, VDR. In this review, we address vitamin D/VDR signaling and how it …

Accumulating data support that vitamin D possesses several biological and molecular
actions apart from its role in calcium homeostasis. Immune cells express vitamin D receptor …
