From: Effect of age and sex on immune checkpoint expression and kinetics in human T cells
Kinetics of immune checkpoint expression. T cells were stimulated and immune checkpoint expression was measured at several time points thereafter. Graphs illustrate median percentages of CD40L, PD-1 and VISTA in total CD4+ cells (a) and CD8+ cells (b) at indicated time points (n = 10 young and 10 older adults). Blue and orange solid lines represent the median expression percentages of young (YA) and older adults (OA), respectively. Dotted blue and orange lines represent unstimulated cells. Error bars indicate interquartile range
