Clinical Scorecard: Dysfunction and Exhaustion of Regulatory T Cells in Uveitis: Immunometabolic Factors, Environmental Influences, and Novel Treatment Approaches

At a Glance

Key Highlights

• Tregs are crucial for maintaining ocular homeostasis and preventing inflammation.
• Distinct patterns of Treg dysfunction are observed in different uveitis subtypes.
• Extrinsic factors like gut microbiota and circadian rhythm affect Treg functionality.
• Therapeutic strategies include immune checkpoint modulation and metabolic reprogramming.
• Treg exhaustion is linked to persistent ocular inflammation and disease recurrence.

Guideline-Based Recommendations

Diagnosis

• Assess Treg function and exhaustion markers in uveitis patients.
• Differentiate between uveitis subtypes based on T cell profiles.

Management

• Consider low-dose interleukin-2 therapy to expand Tregs.
• Utilize adoptive transfer of ex vivo-expanded Tregs.

Monitoring & Follow-up

• Regularly evaluate Treg stability and functionality in treatment response.
• Monitor for signs of inflammation recurrence.

Risks

• Potential adverse effects from immunosuppressive therapies.
• Risk of visual impairment and blindness due to chronic inflammation.

Patient & Prescribing Data

Patients with chronic non-infectious uveitis, especially those unresponsive to standard therapies.

Innovative therapies targeting Treg restoration show promise in clinical settings.

Clinical Best Practices

• Integrate assessment of immune profiles from both peripheral blood and ocular tissues.
• Tailor treatment strategies based on specific uveitis subtype and Treg status.
• Educate patients on the importance of adherence to therapy to prevent disease recurrence.
