Overview of emerging therapies for demyelinating diseases.

Abstract

This paper provides an overview of autoimmune disorders of the central nervous system, specifically those caused by demyelination. We explore new research regarding potential therapeutic interventions, particularly those aimed at inducing remyelination. Remyelination is a detailed process, involving many cell types-oligodendrocyte precursor cells (OPCs), astrocytes, and microglia-and both the innate and adaptive immune systems. Our discussion of this process includes the differentiation potential of neural stem cells, the function of adult OPCs, and the impact of molecular mediators on myelin repair. Emerging therapies are also explored, with mechanisms of action including the induction of OPC differentiation, the transplantation of mesenchymal stem cells, and the use of molecular mediators. Further, we discuss current medical advancements in relation to many myelin-related disorders, including multiple sclerosis, optic neuritis, neuromyelitis optica spectrum disorder, myelin oligodendrocyte glycoprotein antibody-associated disease, transverse myelitis, and acute disseminated encephalomyelitis. Beyond these emerging systemic therapies, we also introduce the dimethyl fumarate/silk fibroin nerve conduit and its potential role in the treatment of peripheral nerve injuries. Despite these aforementioned scientific advancements, this paper maintains the need for ongoing research to deepen our understanding of demyelinating diseases and advance therapeutic strategies that enhance affected patients' quality of life.
