Normal human pulmonary alveolar macrophages ( PAM ) are less sensitive to 1,25(OH)2D3 than PBM , despite similar vitamin D receptor content ; however, both PBM and PAM respond to exogenous 1,25-(OH)2D3 by inhibiting 1,25(OH)2D3 synthesis and inducing 1,25(OH)2D3 degradation through enhancement of 24-hydroxylase mRNA levels and activity.
