Vitamin D3 VitD insufficiency is postulated to represent a major modifiable risk factor for multiple sclerosis MS. While low VitD levels strongly correlate with higher MS risk in white populations, this is not the case for other ethnic groups, suggesting the existence of a genetic component. Moreover, VitD supplementation studies in MS so far have not shown a consistent benefit. We sought to determine whether direct manipulation of VitD levels modulates central nervous system autoimmune disease in a sex-by-genotype-dependent manner. To this end, we used a dietary model of VitD modulation, together with the autoimmune animal model of MS, experimental autoimmune encephalomyelitis EAE. EAE protection was accompanied by sex- and genotype-specific suppression of proinflammatory transcriptional programs in CD4 T effector cells, but not CD4 regulatory T cells.

Instead of focusing on the anatomy of sex — the biological prophecies by which, some say, our bodies were made to meld into one — my mother chose to emphasize pleasure. She spoke about the importance of passion: pursuing it, asking for it and finding it within yourself.
