Multiple sclerosis (MS) is an immune-mediated disease affecting the central nervous system (CNS). This review details immune cell roles in MS pathogenesis and discusses current immunomodulatory treatments.

Area of Science:

Neuroimmunology
Immunology

Background:

Multiple sclerosis (MS) is an immune-mediated disorder impacting the central nervous system (CNS).
Immune cells breach the blood-brain barrier, exacerbating neuropathology in MS.
The precise causes of MS remain elusive, with potential contributions from genetics, environment, and infections.

Purpose of the Study:

To elucidate the roles of diverse immune cell types in the development and progression of MS.
To explore the involvement of CNS-resident cells and molecular mediators in MS pathogenesis.
To review the mechanisms of immunomodulatory therapies used for MS treatment.

Main Methods:

Comprehensive review of scientific literature on immune cell involvement in MS.
Discussion of T cells, antigen-presenting cells, innate immune components (macrophages, B cells, complement system), and CNS-specific cells (microglia, astrocytes, neurons).

Examination of the role of chemokines and matrix metalloproteinases in immune cell recruitment to the CNS.

Main Results:

Detailed description of the contribution of various immune cells, including regulatory T cells, to MS pathology.
Identification of key molecular mechanisms, such as chemokines and matrix metalloproteinases, involved in immune cell infiltration into the CNS.
Consideration of genetic, environmental, and infectious factors potentially contributing to MS immune dysregulation.

Conclusions:

Immune cell dysregulation is central to MS pathogenesis.
Understanding the intricate interplay of immune cells and CNS components is crucial for MS treatment.
Further research into causative factors and immunomodulatory mechanisms is essential for effective MS management.
