Multiple Sclerosis PBMC

About Multiple Sclerosis PBMC

Multiple Sclerosis PBMC for Neuroimmunology and Autoimmunity Research

Multiple Sclerosis (MS) Human PBMC are sourced from IRB-consented donors clinically diagnosed with MS, processed within 24 hours of collection and cryopreserved in CryoStor® CS10. MS is an autoimmune disease of the central nervous system in which lymphocytes cross the blood-brain barrier and drive demyelination and axonal loss. Because the pathogenic cells originate in and traffic through the blood, cryopreserved peripheral blood mononuclear cells are the workhorse specimen for MS immunology and drug development.

Why PBMC for Multiple Sclerosis

Nearly every approved disease-modifying therapy in MS acts on a peripheral blood leukocyte — by depleting it, sequestering it, or blocking its migration. That makes PBMC not merely a convenient surrogate but the actual target compartment.

• Myelin-reactive T cells — CD4+ Th1 and Th17 cells reactive to myelin antigens are central to MS pathogenesis, and PBMC support antigen-specific stimulation, proliferation and cytokine recall assays that cannot be done in serum or plasma.
• B cells are pathogenic, not incidental — the striking efficacy of anti-CD20 therapy established B cells as central to MS. PBMC allow memory B-cell phenotyping, depletion pharmacodynamics and repopulation kinetics to be measured directly.
• Lymphocyte trafficking mechanisms — natalizumab blocks alpha-4 integrin (VLA-4) and S1P receptor modulators trap lymphocytes in lymph nodes; both mechanisms are assayed on intact PBMC through adhesion, migration and receptor-expression readouts.
• Regulatory T-cell function — impaired regulatory T-cell suppressive capacity is a recurring finding in MS and requires live, functional cells to test.
• CD8+ T cells and tissue-resident phenotypes — CD8+ T cells dominate MS lesions, so circulating CD8 differentiation and clonality are informative, particularly alongside TCR sequencing.
• Epstein-Barr virus biology — the strong epidemiologic link between EBV infection and MS is investigated using EBV-specific T-cell and B-cell responses, which requires viable PBMC for antigen recall assays.
