FOXP3

FoxP3 (pour forkhead box P3) est un facteur de transcription spécifique des lymphocytes T régulateurs, codé par le gène FOXP3, situé sur le chromosome X humain. Il est un membre de la famille de protéines de type FOX. Ce gène code lui-même le répresseur de transcription Scurfin.

L'article doit être débarrassé d'une partie de son jargon (juin 2015).

FoxP3 est essentiel pour l'acquisition de propriétés immuno-régulatrices par les lymphocytes T CD4+CD25+, on peut dire que FoxP3 est le "rhéostat de la réponse immunitaire".
