Comment Clemastine fumarate for promotion of optic nerve remyelination

The regulatory approval of 15 disease-modifying medications to reduce inflammatory lesion activity in relapsing multiple sclerosis illustrates the dramatic progress made in the treatment of this frequently disabling condition. None of these medications, however, directly promotes repair of the damaged CNS. As a result, therapies to prevent accumulation of permanent disability and, especially, to reverse pre-existing disability represent major unmet needs.

In this study we assessed the effect of fingolimod on transplanted human induced pluripotent stem cell derived neural progenitors (hiPSC-NPs). hiPSC-NPs were labeled by green fluorescence protein (GFP) and transplanted into the corpus callosum of mice which were chronically demyelinated after cuprizone (CPZ) feedings for 10 weeks. The animals received fingolimod from 1 day prior to NPs transplantation via gavage as well as daily intraperitoneal cyclosporine A from 2 days before cell transplantation until the time of sampling. At either 7 or 21 days after NPs transplantation, the animals were sacrificed and their brains wer...

Authors: Genc B, Bozan HR, Genc S, Genc K Abstract Multiple sclerosis (MS) is a chronic inflammatory, autoimmune, and neurodegenerative disease of the central nervous system (CNS). It is characterized by demyelination and neuronal loss that is induced by attack of autoreactive T cells to the myelin sheath and endogenous remyelination failure, eventually leading to functional neurological disability. Although recent evidence suggests that MS relapses are induced by environmental and exogenous triggers such as viral infections in a genetic background, its very complex pathogenesis is not completely understood. Theref...

(Case Western Reserve University) Research published today in the journal Nature provides new understanding about how drugs can repair damaged brain cells that cause disability in patients with multiple sclerosis. Led by researchers at Case Western Reserve University School of Medicine, the study suggests new drug targets and potent early-stage drug candidates could lead to regenerative medicines for multiple sclerosis and other debilitating neurological diseases.

AbstractMultiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system (CNS) characterized by neuroinflammation, neurodegeneration and impaired repair mechanisms that lead to neurological disability. The crux of MS is the patient ’s own immune cells attacking self-antigens in the CNS, namely the myelin sheath that protects nerve cells of the brain and spinal cord. Restoring antigen-specific tolerance via therapeutic vaccination is an innovative and exciting approach in MS therapy. Indeed, leveraging the body’s attempt to prevent autoimmunity, i.e., tolerization, focuses on the underl...

In conclusion, senescence of vascular cells promotes the development of age-related disorders, including heart failure, diabetes, and atherosclerotic diseases, while suppression of vascular cell senescence ameliorates phenotypic features of aging in various models. Recent findings have indicated that specific depletion of senescent cells reverses age-related changes. Although the biological networks contributing to maintenance of homeostasis are extremely complex, it seems reasonable to explore senolytic agents that can act on specific cellular components or tissues. Several clinical trials of senolytic agents are currentl...

Ongoing axonal degeneration is thought to underlie disability in chronic neuroinflammation, such as multiple sclerosis (MS), especially during its progressive phase. Upon inflammatory attack, axons undergo pathological swelling, which can be reversible. Because we had evidence for beneficial effects of T helper 2 lymphocytes in experimental neurotrauma and discovered interleukin-4 receptor (IL-4R) expressed on axons in MS lesions, we aimed at unraveling the effects of IL-4 on neuroinflammatory axon injury. We demonstrate that intrathecal IL-4 treatment during the chronic phase of several experimental autoimmune encephalomy...

FINDINGSA study by UCLA researchers reveals the cellular basis for how the hormone estrogen protects against damage to the central nervous system in women with multiple sclerosis, or MS. The researchers found that estrogen treatment exerts positive effects on two types of cells during disease — immune cells in the brain as well as cells called oligodendrocytes.BACKGROUNDUCLADr. Rhonda VoskuhlMultiple sclerosis is a chronic autoimmune, neurodegenerative disease marked by visual impairment, weakness and sensory loss, as well as cognitive decline. These symptoms emerge when inflammatory immune cells destroy the myelin s...
