Association between Hippo signaling pathway and myelination process in the Multiple sclerosis

Multiple sclerosis is an autoimmune inflammatory disease that causes the destruction of myelin and axonal degeneration. Given that multiple sclerosis is one of the most common neurological diseases, especially in young people, this disease is one of the main public health concerns. Therefore, it is important to understand the molecular mechanisms involved in the development of MS. Many molecular mechanisms control the process of myelination in the nervous system, and any changes in these regulatory mechanisms lead to impaired myelination. Current therapies have focus on controling the immune mechanisms involved in the disease process and are therefore only effective in the early stages of the disease and have no effect on axonal remyelination. But, therapies that reinforce the remyelination process may delay or prevent disability. Some recent studies have investigated the role of key genes of the Hippo signaling pathway in the myelination process of myelinating glial cells. According to these studies, the activity of YAP1/TAZ and its negative regulation in the Hippo pathway via CRB3, a cellular polarization factor, regulates myelin sheath synthesis. Thus, dysregulation of these genes can play a major role in the pathogenesis of many diseases related to the nervous system. Because there is no comprehensive review of the relationship between the hippo signaling pathway and multiple sclerosis; in this study, in addition to a narrative review of MS and its predisposing factors, the Hippo pathway as a pathway implicated in the defect of the myelination process in MS was investigated.
