Abstract

Abstract Views: 0

The 2025 Nobel Prize in Physiology or Medicine has been awarded to the researchers who identified regulatory T cells, abbreviated as Tregs, a groundbreaking discovery concerning peripheral immune tolerance. These cells protect our body from autoimmune diseases. The fields of immunology and clinical medicine have been influenced by their discoveries. With the increased knowledge of immunology, novel therapeutic strategies for the treatment of allergies, lethal autoimmune diseases, and organ transplant rejection are being introduced. While, targeted therapies to restore immune balance are expected.

This study first identified CD4⁺CD25⁺ T cells as key regulators of self-tolerance, showing that their absence leads to multiple autoimmune diseases.

This study revealed that mutations in the FOXP3 (scurfin) gene cause the lethal autoimmune scurfy phenotype in mice, establishing FOXP3 as essential for immune regulation.

This review traces the discovery of FOXP3 and the scurfy mutation, highlighting how these findings established FOXP3 as the lineage-defining transcription factor required for regulatory T-cell development and immune tolerance.
