The authors developed iPSCs from secondary progressive multiple sclerosis (SPMS)-affected donors and age-matched controls (CT). They confirmed their efficient and similar oligoprogenitor (OPC) differentiation capacity, although they reported SPMS-OPCs were transcriptionally distinguishable from their CT counterparts.
Investigators used two-photon microscopy to elucidate the spatial organization, motility characteristics, and interactions of endogenous Treg and Th17 cells together with antigen-presenting cells within the spinal cord leptomeninges in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis.
