Vitamin D has been extensively studied for bone health and cancer, as well as for its anti-inflammatory benefits and also its role in modulating the immune system in autoimmune diseases.
Autoimmune disorders occur when the body’s immune system is tricked into thinking that the body’s own healthy tissues are foreign and starts attacking itself. As a result, the immune system makes antibodies that attack various tissues.
Previous studies have demonstrated that vitamin D decreases the disease severity in autoimmune disorders by regulating T cells in the immune system. This makes the body more tolerant of itself and less likely to mount autoimmune responses.
According to a new study published four days ago in The Journal of Cell Biology, researchers identified that the vitamin D receptor promotes the differentiation of oligodendrocyte progenitor cells (OPCs) and increases myelin sheath regeneration.
Patients with multiple sclerosis (MS) continue to lose the myelin sheath (insulation) around the neurons. When these neurons become demyelinated, OPCs migrate toward these cells and they differentiate into mature, myelin-producing oligodendrocytes. This process or ability, however, decreases as we age.
Low vitamin D levels have been associated with the onset of multiple sclerosis. This suggests a new role with vitamin D and MS patients. In addition to its impact on immune function, vitamin D may also affect the disease progression by controlling myelin sheath regeneration, thus enhancing remyelination in MS patients and in patients suffering from other demyelinating diseases.
In addition to the consideration of vitamin D, it is important to assess the gut in all autoimmune disorders.
