Increased levels of CD8+ cells in HNSCC tissue from patients treated with 1,25(OH)2D3. Numbers of immunostained cells per microscopic field were enumerated in HNSCC tissues from untreated and 1,25(OH)2D3-treated patients. Shown are the averages of the numbers of immunostained cells for at least 2 separate slides for each patient, each counted independently by four blinded scorers. Shaded areas represent SEM.
