In contrast, we found no differences between RA patients and HD in the percentages of CXCR5+ CD4+ T cells or in the frequencies of CXCR3+CCR6− (Tfh1), CXCR3-CCR6- (Tfh2), and CXCR3-CCR6+ (Tfh17) cell subsets in a small cohort of 24 patients from Argentina (23). The gene discussed is CXCR3; the disease is Huntington disease.
