Analysis of receptors expressed by TFH cells. (a) Representative gating strategy showing the increased expression of CD200 on TFH cells from patients with RA. (b) Significantly increased expression of CD200 and CD150 was detected on circulating TFH cells from seropositive RA patients (SP: seropositive, SN: seronegative) (P = 0.0045 and P = 0.0088, resp.). Each spot represents an individual patient, and the mean ± SEM are shown. (c) CD200 expression is enriched on CXCR5 positive CD4+ T cells in patients with RA.
