NR3C1 and Anxiety: Regression analysis supported this finding (B Lymphocyte GR, F = 4.95, P = 0.032; Natural Killer Cell GR, F = 6.23, P = 0.017; Monocyte GR, F = 5.47, P = 0.024) Since glucocorticoid sensitivity is determined by both the GR level on any individual cell and the total number of cells available to present GR for glucocorticoid binding, the composite score of anxiety proneness is arguably the most accurate anxiety-related measure to use in data reduction and interpretation, at least in the current study.
