Fig. 1From: Altered composition and phenotype of mucosal-associated invariant T cells in early untreated rheumatoid arthritisMAIT cells present in peripheral blood, synovial fluid and synovium. a, b MAIT cells present in both blood (PB, a) and synovial fluid (SF, b) and frequencies of total MAIT cells (CD3+MR1-tet+) in PB and SF are comparable between groups. c, d Representative images of SpA (c) and RA (d) synovium confirming MAIT cells are also present within synovium of SpA and RA patients. MAIT cells, triangles; B cells, asterisks. MAIT cells defined as CD3+CD161+Vα7.2+ and B cells as CD19+. (1) CD3; (2) CD19; (3) Hoechst; (4) CD161; (5) Vα7.2.
