Nieuwe publicatie: Osteopontin associates with brain TRM-cell transcriptome and compartmentalization in donors with and without multiple sclerosis

The human brain is populated by perivascular T cells with a tissue-resident memory T (TRM)-cell phenotype, which in multiple sclerosis (MS) associate with lesions. Cheng-Chih Hsiao and Jeen Engelenburg investigated the transcriptional and functional profile of freshly isolated T cells from white and gray matter. RNA sequencing of CD8+ and CD4+ CD69+ T cells revealed TRM-cell signatures. Notably, gene expression hardly differed between lesional and normal-appearing white matter T cells in MS brains. Genes up-regulated in brain TRM cells were MS4A1 (CD20) and SPP1 (Osteopontin).
