Characterization of severe acute respiratory syndrome coronavirus 2 reactive T and B cells in transplant and non-transplant donors. (A) CD4+CD154+CD137+ showed no significant statistical difference among transplant and non-transplant patients. (B) Analysis of the monofunctional CD4+CD154+CD137+ cells. (C) Correlation of CD4+CD154+CD137+CXCR5+ among patients who had undergone transplant those who had not. (D) Analysis of fluorochrome severe acute respiratory syndrome coronavirus 2 S-protein binding B cells among the unexposed cohort of patients who had undergone transplant vs patients who were immunocompetent (P = .1588). Statistical comparison was done with the Mann-Whitney test. P < .05 was considered significant, and only significant P values are documented in the figures.
