Area of Science:

  • Immunology
  • Autoimmunity

Context:

  • B cells are increasingly recognized for their significant roles in autoimmune disease pathogenesis.
  • Dysfunctional B cell activity contributes to autoantibody production, cytokine secretion, and antigen presentation.

Purpose:

  • To review the critical roles of B cells in autoimmune diseases.
  • To discuss the therapeutic potential and clinical efficacy of Rituximab, a CD20-targeting monoclonal antibody, in managing autoimmune conditions.

Summary:

  • B cells contribute to autoimmunity through autoantibody production, cytokine secretion, antigen presentation, and co-stimulation.
  • Rituximab selectively targets CD20-expressing B cells, demonstrating significant clinical efficacy in rheumatoid arthritis and systemic lupus erythematosus.
  • Long-term B cell depletion with Rituximab leads to sustained symptom improvement in autoimmune patients.
