Altered cholesterol, oxysterol, sphingolipid, and fatty acid concentrations are reported in blood, cerebrospinal fluid, and brain tissue of people with relapsing remitting multiple sclerosis (RRMS) and are linked to disease progression and treatment responses. CD4+ T cells are pathogenic in RRMS, and defective T cell function could be mediated in part by liver X receptors (LXRs) - nuclear receptors that regulate lipid homeostasis and immunity. RNA-sequencing and pathway analysis identified that genes within the 'lipid metabolism' and 'signalling of nuclear receptors' pathways were dysregulated in CD4+ T cells isolated from RRMS patients compared with healthy donors...
