SELPLG and myeloid sarcoma: In MS patients, expression of VLA-4 was significantly higher in MAIT cells than in non-MAIT cells, with greatest expression occurring during exacerbations (p = 0.01 to p < 0.001; Supplementary Figure S2D), whereas no significant difference was observed between cell populations in LFA-1, PSGL-1, and LFA-3 surface expression (p = 0.33 to p = 0.69; Supplementary Figures S2E–G).
