Special Issue Information

Dear Colleagues,

Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD), including myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), is one of the most exciting, emerging fields in neurology. Recent pathophysiological insights, derived from both animal models and clinical studies, paved the way for the regulatory approval of novel therapies, like oral compounds, small molecules, or monoclonal antibodies. Some of these compounds possibly act beyond their well-established immunomodulatory properties, for instance, by inducing direct neuroprotection or neuroregeneration. Of note, childhood MS, NMOSD, and MOGAD have been recognized as significant medical problems, and novel therapies are increasingly tested for this population. However, important, unmet medical needs remain, and the quest for even more sophisticated treatment strategies continues. For example, promising preclinical and clinical data exist regarding the modulation of costimulatory molecules and kinases in immune cells, B cell function, and the functional state of the blood–brain barrier. In addition, improved biomarkers beyond neurofilament light chain (Nfl) and imaging techniques, such as diffusion tensor imaging (DTI) or optical coherence tomography (OCT), have helped gain in vivo insights into the pathophysiological processes directly acting in patients.

The upcoming Special Issue on "The Role of Autoimmunity in Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder" will cover all aspects of this most prevalent neuroimmunological disease. We invite authors to submit original articles or state-of-the-art reviews on MS pathophysiology, therapy, epidemiology, environmental factors, and imaging. All contributions will undergo a rapid, fair, and concise review process to minimize publication times. We look forward to receiving your valuable submissions.

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system. The therapeutic landscape for MS has evolved significantly since the 1990s, with the development of more than 20 different disease-modifying therapies (DMTs). These therapies effectively manage relapses and inflammation, but most have failed to meaningfully prevent disease progression. While classically understood as a T cell-mediated condition, the most effective DMTs in slowing progression also target B cells. Novel classes of MS therapies in development, including anti-CD40L monoclonal antibodies, CD19 chimeric antigen receptor (CAR) T cells, and Bruton’s tyrosine kinase (BTK) inhibitors show greater capacity to target and eliminate B cells in the brain/CNS, as well as impacting T-cell and innate immune compartments. These approaches may help tackle the disease at its immunopathological core, addressing both peripheral and central immune responses that drive MS progression. Another emerging therapeutic strategy is to use bispecific antibodies, which have the potential for dual-targeting various disease aspects such as immune activation and neurodegeneration. As such, the next generation of MS therapies may be the first to reduce both inflammatory demyelination and disease progression in a clinically meaningful way. Their ability to target specific immune cell populations while minimizing broad immune suppression could also lead to better safety profiles. Here, we explore the biological rationale, advantages, limitations, and clinical progress of these emerging immunotherapies for relapsing–remitting and progressive forms of MS. Full article
