CXCR5 and Huntington disease: When assessing B cells expressing or not CD11c and CXCR5 (Fig. 2A) we found that CD11c + CXCR5-and CD11c-CXCR5-were significantly more frequent in SLE than in HD, while CD11c-CXCR5+ cells were more frequent in HD than in SLE, with no significant differences in the CD11c + CXCR5+ subset (Fig. 2B).
