Effect of vitamin D supplementation on antibody-dependent and antibody-independent antitumor NK cell activity. The antitumoral activity of NK cells isolated from HNSCC patients, directed against FaDu cells is shown before and after substitution as relative FaDu cell lysis. Each bar represents the mean value of 9 HNSCC patients with a significant rise in vitamin D serum level (Δ > 10 ng/ml; vitamin D responder). The error bars indicate the standard error of the mean.
