Title |
Transcriptional profiling of brain CD4+ and CD8+ TRM cells reveals dominant presence in white and grey matter in Multiple Sclerosis (MS) |
Organism |
Homo sapiens |
Experiment type |
Expression profiling by high throughput sequencing

Summary |
The human brain is populated by perivascular CD8+ and CD4+ T cells with a tissue-resident memory T (TRM)-cell phenotype. In multiple sclerosis (MS), these cells associate with white matter (WM) and, to a lesser extent, grey matter (GM) lesions. We here investigated the transcriptional and functional profile of brain-resident T cells. Of n=11 subsequent post-mortem brain donors, we isolated CD8+ and CD4+ effector memory and effector memory re-expressing CD45RA T cells from blood and CD8+ and CD4+ CD69+ T cells from corpus callosum WM and cortical GM. Additionally, brain CD69+ T cells were sorted from subcortical WM, corpus callosum WM, and medulla WM/GM of n=3–5 brain donors as well as from paired normal-appearing WM and GM and from WM and GM lesions of n=6 MS brain donors. In all donors, WM and GM T cells were overwhelmingly CD69+CD103+/-. Bulk RNA sequencing of CD8+ and CD4+ CD69+ T cells revealed TRM-cell signatures, as marked by differential expression of, among others, SELL (CD62L), ITGA1 (CD49a), and S1PR1. Notably, gene expression hardly differed between lesional and normal-appearing WM CD8+ and CD4+ CD69+ T cells in MS brains. Genes up-regulated in brain TRM cells were MS4A1 (CD20) and SPP1 (osteopontin, OPN). OPN is also abundantly expressed by microglia and has been shown to inhibit T-cell activity. In line with the increased presence of OPN in active MS lesions, we noticed a reduced production of the inflammatory cytokines IL-2, TNF, and IFNγ by MS lesion-derived CD8+ and CD4+ T cells ex vivo. This study discloses essential characteristics of human brain CD8+ and CD4+ TRM cells in non-MS and MS post-mortem WM and GM, reports OPN as a generic product of brain-resident immune cells, and shows a tight control of the activation state of TRM cells in MS lesions.
