A similar profile was observed amongst CD4+ T cells from blood and CSF of MS/CIS patients, including increased expression of genes related to tissue migration (ITGB1, CD69, ITGA4, CXCR3, CXCR4) and cytokine secretion (IL32, GZMK) and reduced naïve status (CCR7, LEF1, SELL, TCF7) and TCR signaling (LCK) (Fig. 1I, Table S4). The gene discussed is CD4; the disease is in situ carcinoma.
