CD8A and myeloid sarcoma: In line with this observation, GR gene expression in CD8+ T cells from a different cohort demonstrated a moderate reduction in individuals with severe 25D deficiency (mean (SE) log2 GR gene expression: serum 25D level: < 25 nmol/l: 9.94 (0.14), n = 5 (n = 2 healthy controls/n = 3 stable MS patients); ≥ 25 nmol/l: 10.09 (0.14), n = 107 (n = 61 healthy controls/n = 46 stable MS), p < 0.05, Affymetrix human gene 1.0 ST chip).
