Fig 1. 1,25(OH)2D3 increased the ability of murine alveolar macrophages to stimulate in vitro NK cell cytotoxicity.

NK cells, from spleen of C57BL/6 healthy mice, co-cultured with 1,25(OH)2D3-pretreated lung macrophages significantly increased the percentage of lysis of YAC-1 cells, as compared to NK cells co-cultured with untreated lung macrophages. Unpaired t test; *p<0.05.
