Purification, Phenotypic and Functional Analyses of Regulatory T Cells in Autoimmunity

Area of Science:

• Immunology
• Cell Biology
• Autoimmunity

Background:

• Regulatory T cells (Tregs) are crucial for immune homeostasis.
• Dysfunctional Tregs are implicated in autoimmune diseases like rheumatoid arthritis.

Purpose of the Study:

• To describe methods for isolating and purifying human CD4+ Tregs.
• To analyze Treg phenotypes and functions.
• To discuss Treg-based therapeutic strategies for autoimmune diseases.

Main Methods:

• Isolation of Tregs from peripheral blood and synovial fluid using flow cytometry-based cell sorting.
• Phenotypic analysis via surface and intracellular staining.
• Functional assessment using in vitro suppression assays.

Main Results:

• Separation of naïve and effector Treg populations.
• Detailed characterization of Treg subsets.
• Established methods for Treg analysis and functional testing.

Conclusions:

• The described methods enable robust isolation and characterization of human Tregs.
• These techniques support the development of Treg-based immunotherapies for autoimmune conditions.
