T Lymphocytes in Parkinson's Disease

Area of Science:

• Neuroimmunology
• Immunology
• Neurology

Background:

• T cells are central to adaptive immunity, mediating both humoral and cellular responses.
• Emerging evidence implicates T cells in the pathogenesis of Parkinson's disease (PD).
• T cell involvement spans both the central nervous system and peripheral systems, disrupting immune balance in PD.

Purpose of the Study:

• To review the multifaceted role of T cells in Parkinson's disease.
• To explore T cells as potential biomarkers for disease progression.
• To discuss emerging therapeutic strategies targeting T cell modulation in PD.

Main Methods:

• Comprehensive review of preclinical studies on T cells in PD models.
• Analysis of clinical studies investigating T cell involvement in PD patients.
• Examination of current and novel therapeutic approaches modulating T cell responses.

Main Results:

• T cells are significantly implicated in the neuroinflammatory processes of Parkinson's disease.
• T cell populations and functions are altered in PD patients, correlating with disease progression.
• Modulating T cell responses presents a promising avenue for Parkinson's disease therapeutics.

Conclusions:

• T cells are critical players in Parkinson's disease pathogenesis and progression.
• T cells represent valuable biomarkers for monitoring motor and non-motor symptoms in PD.
• Targeting T cell pathways offers a viable strategy for future Parkinson's disease treatments.
