Acute erythemal ultraviolet radiation causes systemic immunosuppression in the absence of increased 25-hydroxyvitamin D3 levels in male mice.
Vitamin D is synthesised by ultraviolet (UV) irradiation of skin and is hypothesized to be a direct mediator of the immunosuppression that occurs following UV radiation (UVR) exposure. Both UVR and vitamin D drive immune responses towards tolerance by ultimately increasing the suppressive activities...

Vitamin D is synthesised by ultraviolet (UV) irradiation of skin and is hypothesized to be a direct mediator of the immunosuppression that occurs following UV radiation (UVR) exposure. Both UVR and vitamin D drive immune responses towards tolerance by ultimately increasing the suppressive activities of regulatory T cells. To examine a role for UVR-induced vitamin D, vitamin D(3)-deficient mice were established by dietary vitamin D(3) restriction. In comparison to vitamin D(3)-replete mice, vitamin D(3)-deficient mice had significantly reduced serum levels of 25-hydroxyvitamin D(3) (25(OH)D(3), <20 nmol.L(-1)) and 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3), <20 pmol.L(-1)). Following either acute erythemal UVR, or chronic sub-erythemal UVR (8 exposures over 4 weeks) treatment, serum 25(OH)D(3) levels significantly increased in vitamin D(3)-deficient female but not male mice. To determine if UVR-induced vitamin D was a mediator of UVR-induced systemic immunosuppression, responses were measured in mice that were able (female) or unable (male) to increase systemic levels of 25(OH)D(3) after UVR.

Thus, in male mice, UVR-induced 25(OH)D(3) is not essential for mediating the immunosuppressive effects of erythemal UVR. |
