We aimed to examine genetic and nongenetic determinants of change in serum 25-hydroxyvitamin D (25(OH)D) after supplementation.

What is the optimal level of vitamin D?: Separating the evidence from the rhetoric

New evidence indicates that both high and low 25(OH)D levels may be associated with increased health risks.

Vitamin D deficiency causes airway hyperresponsiveness and increases airway smooth muscle mass in the lungs of female BALB/c mice

We tested whether there is a causal association between vitamin D deficiency, airway smooth muscle (ASM) mass, and the development of airway hyperresponsiveness

Results from studies examining associations between serum 25-hydroxyvitamin D (25(OH)D) concentrations and depressive symptoms are equivocal.

Characterization of regulatory dendritic cells differentiated from the bone marrow of UV-irradiated mice

In summary, UV-BMDCs do not express the classical phenotypic or gene expression properties of DCs reported by others as 'regulatory' or 'tolerogenic'.
