Fig. 1. In both groups, acute psychological stress led to a significant increase over rest in circulating levels of CD8⁺CD62L^- (top) and CD8⁺CD62L⁺ (bottom) T cells (p<.001). Compared with nonvulnerable caregivers, vulnerable caregivers had lower levels of CD8⁺CD62L^- cells at rest and following the task (p=.01) but no difference in CD8⁺CD62L⁺ cells (mean,±SEM).
