From: Racial differences in B cell receptor signaling pathway activation
IgD+ B cell percentages in AA and EA donors. CD20- lymphocytes were used as an internal negative control to define the IgD+ region for each donor. The IgD+ region was applied to the viable B cell subpopulation to determine the IgD+ B cell percentage for each donor. Representative flow plots from one healthy donor are shown. IgD+ B cell percentages were assessed under the unmodulated condition. EAs had a higher percentage of IgD+ B cells than AAs and the race-associated difference was significant (p = 0.016, Wilcoxon test).
