V. Mechanisms of High-Dose Vitamin D in MS Treatment
5.1 Regulation of Autoimmunity Multiple sclerosis is characterized by an abnormal immune response, where the immune system mistakenly attacks the myelin sheath in the central nervous system. High-dose vitamin D has been shown to regulate the immune response by promoting the differentiation of regulatory T cells (Tregs) and inhibiting the production of pro-inflammatory cytokines. Tregs play a crucial role in maintaining immune balance and suppressing autoimmunity. By promoting Treg function, high-dose vitamin D may help modulate the immune system and reduce the attack on myelin in individuals with MS.
5.2 Modulation of Inflammation Inflammation is a key contributor to the pathogenesis of MS. High-dose vitamin D has anti-inflammatory properties and can reduce the production of pro-inflammatory cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). By suppressing inflammation, high-dose vitamin D may help alleviate the immune-mediated damage to myelin and neural tissue in individuals with MS.
5.3 Promotion of Neuroprotection and Remyelination Neuroprotection and remyelination are crucial for preserving neural function and preventing disability progression in MS. High-dose vitamin D has been shown to promote neuroprotective mechanisms and support remyelination processes. It enhances the production of neurotrophic factors, such as brain-derived neurotrophic factor (BDNF), which promote neuronal survival and growth. Additionally, high-dose vitamin D may stimulate oligodendrocyte precursor cells, which are responsible for remyelination in the central nervous system.
VI. Clinical Evidence of High-Dose Vitamin D in MS Treatment
