Calcitriol upregulates VDR expression in activated peripheral blood T lymphocytes from female and male healthy donors. VDR levels were evaluated by Western blot analysis of T cell lysates after 48 h of calcitriol treatment. (A) Blots shown are representative of experiments performed in T cells from 10 randomly selected female and male healthy subjects. (B) Densitometry analysis of VDR levels relative to glyceraldehyde 3−phosphate dehydrogenase (GAPDH) is shown. Results are shown as mean ± SD. * p < 0.05 versus untreated cells.
