In contrast, additional phenotyping of CD4+CD45RA- memory T cells demonstrated an expansion of CXCR5-expressing T follicular helper (TFH)-like cells (Figure 2A) with a significant increase of CXCR3-expressing TFH1-like cells and a decrease of CCR6-expressing TFH17-like cells when compared to sarcoidosis (Figure 2A). This evidence concerns the gene CCR6 and sarcoidosis.
