Key Takeaway
Note the absence of reported outcome data and safety metrics in this systematic review.

This publication is classified as a systematic review investigating therapeutic approaches and immunological mechanisms within the context of multiple sclerosis. The authors synthesized information regarding T-cell-mediated immunodysregulation mechanisms, disease-modifying therapies, emerging therapies, and traditional herbal medicines. The scope encompasses a broad evaluation of these distinct categories to understand their potential roles in disease management.

However, the provided documentation indicates that specific study populations, sample sizes, and settings were not reported. Furthermore, primary outcomes, secondary outcomes, and follow-up durations are listed as not reported in the source data. Safety information, including adverse events, serious adverse events, discontinuations, and tolerability, was also not reported. The absence of main results means no pooled effect sizes or specific clinical findings can be extracted for this summary. Limitations, funding sources, conflicts of interest, and certainty notes were not reported, which restricts the ability to assess the overall quality or bias of the included evidence. Practice relevance was not reported, limiting direct clinical application guidance.

Clinicians should recognize that while the review covers significant therapeutic areas, the lack of reported numerical data prevents definitive conclusions regarding efficacy or safety. The evidence remains descriptive of the topics rather than quantitative regarding outcomes. Interpretation requires caution due to the missing granular data points typically required for evidence-based decision-making in neurology. The review structure suggests an intent to categorize interventions but lacks the statistical power or data transparency to support specific treatment recommendations. Without reported sample sizes or confidence intervals, the strength of any association between the therapies and outcomes cannot be quantified. This limitation is critical for specialists evaluating treatment options for complex autoimmune conditions. The focus on T-cell mechanisms highlights a theoretical pathway, yet the clinical translation remains unverified in this specific dataset. Readers must rely on the categorization of therapies rather than comparative effectiveness data. Ultimately, the summary serves as a topic overview rather than a definitive clinical guideline due to the extensive gaps in reported metrics.

Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) caused by chronic inflammation. It is the leading cause of neurologic symptoms in young people and leads to progressive neurodegenerative disability. Accumulating evidence indicates that MS arises from the coordinated and co-dominant actions of peripheral immune cells, meningeal tertiary lymphoid structures (TLS), and CNS-resident immune compartments. Within this complex immunopathological network, dysregulated T-cell-mediated adaptive immune responses play a pivotal role in initiating and organizing autoimmune inflammation. Peripherally activated T cells cross the blood-brain barrier (BBB), become reactivated within the CNS, and secrete pro-inflammatory cytokines that drive demyelination and neurodegeneration. Improved understanding of these immune mechanisms has led to the development of disease-modifying therapies (DMTs), many of which directly or indirectly target T-cell function. Here, we adopt a T-cell-centric perspective to systematically review the pathogenic mechanisms of MS, with particular emphasis on recent advances and unresolved questions regarding T-cell subset dysregulation, systematically integrating its precise targeting associations with conventional disease-modifying therapies (DMTs). Simultaneously, the mechanisms of emerging therapies were analyzed, and the potential of traditional herbal medicines was explored. This approach overcomes the limitations of previous studies that focused solely on a single T cell subset or a single therapeutic category.
