Neither actin, arachidonic acid or albumin increases the bioavailability of 25(OH)D 3 for T cells. Relative CD38 cell surface expression on T cells activated for 3 days in the presence of 25(OH)D3 (100 nM) and in the absence or presence of DBP (250 nM) and the indicated concentrations of (A) actin, (B) arachidonic acid or (C) albumin. Mean values ± SEM from 3 independent experiments are plotted.
