Racial disparities in the distribution of Tfh cells.

Abstract

A) Overall Tfh frequencies were similar between African-Americans and Caucasians. However, race related differences were observed in certain Tfh cell subsets including B, C) decreased frequencies of Tfh1 cells in African-Americans at all age ranges, and D, E) increased Tfh17 frequencies in African-Americans, a difference that was observed in all age groups. In C and E, Caucasians are represented by blue bars and African-Americans by orange bars.</p
