Genetics

This blog post examines how vitamin D may influence multiple sclerosis through the genomic activity of the vitamin D receptor. It explores the effects of vitamin D signaling on immune-cell differentiation, inflammatory pathways, vitamin D metabolism genes, enhancer activity, and three-dimensional chromatin organization. By integrating epidemiological evidence with genetics and epigenomics, the article presents vitamin D as an environmental signal that may interact with inherited risk variants to shape immune function and susceptibility to multiple sclerosis.
