Lymphocytes in autoimmune encephalitis: Pathogenesis and therapeutic target.

Area of Science:

• Neuroimmunology
• Central Nervous System Inflammation
• Autoimmune Disorders

Background:

• Autoimmune encephalitis (AE) is a CNS inflammatory condition driven by autoantibodies against neuronal targets.
• The exact causes of AE are still unclear, but lymphocytes are increasingly recognized as key players.
• While autoantibodies are crucial for diagnosis, T lymphocytes' role in AE onset is gaining attention.

Purpose of the Study:

• To review the current understanding of B and T lymphocyte functions in AE pathophysiology.
• To summarize and update the landscape of immunotherapy options for AE treatment.
• To highlight the importance of lymphocytes in AE development and treatment strategies.

Main Methods:

• Literature review of existing research on AE pathogenesis and treatment.
• Analysis of the roles of CD4+ and CD8+ T cells in AE.
• Summary of conventional and novel immunotherapies for AE.

Main Results:

• B and T lymphocytes are integral to AE development.
• CD4+ T cells influence disease via cytokines; CD8+ T cells cause neuronal damage.
• Refractory AE cases benefit from novel therapies like rituximab and CAR-T targeting lymphocytes.

Conclusions:

• Lymphocytes, particularly T cells, are critical in AE pathogenesis.
• Novel immunotherapies targeting lymphocytes offer new hope for refractory AE patients.
• Further research into lymphocyte function can refine AE treatment strategies.
