Enhanced induction of cytotoxic CD8 T cells in females than males in response to SARS-CoV-2. PBMCs stimulated with irradiated SARS-CoV-2 were cultured for 7 days. Cells collected were stained for CD8, perforin, and granzyme B. (A) Dot plot depicts the % of these cells obtained using flow cytometry. (B) Quantitation of cytokines/chemokines in the supernatant by multiplex. Lines connect the unstimulated and stimulated condition from the same subject. Mean ± SE. Females = 15; males = 15. p-value between the control and SARS-CoV-2-stimulated condition in males and females was calculated using Wilcoxon matched pairs signed rank test. Significance between males and females was calculated using unpaired t-test.
