Abstract

Neuroimmunology Myeloid cells, such as dendritic cells and macrophages, in the central nervous system (CNS) play critical roles in the initiation and exacerbation of multiple sclerosis (MS). Jordao et al. combined high-throughput single-cell RNA sequencing and intravital microscopy to compile a transcriptional atlas of myeloid subsets in experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. Microglia and other CNS-associated macrophages expanded and transformed into various context-dependent subtypes during EAE. Furthermore, dendritic cells and monocyte-derived cells, but not resident macrophages, played a critical role by presenting antigen to pathogenic T cells. This exhaustive characterization may inform future therapeutic targeting strategies in MS. Science , this issue p. [eaat7554][1] [1]: /lookup/doi/10.1126/science.aat7554
