Forkhead box P3 (FoxP3), aka Scurfin and JM2, is a protein involving in immune system responses and functioning as a transcriptional regulator crucial in the development and inhibitory of regulatory T-Cells (Treg). FoxP3 is a master regulator of the Treg lineage, who requires Ahr and STAT-5 and other additional transcription factors to retains its complete function and differentiation. Scurfin remains steady and constitutively expressed in two conditions: a high level in CD25 + CD4 positive regulatory T cells and a low level in CD4 positive/CD25 negative cells. JM2 is absent in CD4 negative/CD8 positive T cells. FoxP3 defects are related to various cancers and autoimmune diseases, and X-linked syndrome (IPEX), while overexpression may also cause severe immunodeficiency.
FOXP3 Is has been established that the regulatory transcription factor FOXP3 (a member of the forkhead/winged-helix family of transcription factors) is imperative to immune system homeostasis through CD4+CD25+ regulatory T cell function. Distinctively, ... Read more.
FOXP3: Master Regulatory Transcriptional Factor FOXP3, a forkhead family transcription factor specially expressed in regulatory T (Treg) cells, controls the expression of many key immune-regulatory genes. Treg cells are a population of T lymphocytes that have critical roles in the immune system hom... Read more.
