Células reguladoras en cáncer de piel melanoma y no melanoma
Resumen
Las células T reguladoras (Treg) CD4+CD25+FOXP3+ son cruciales para el
mantenimiento de la tolerancia y la prevención de la autoinmunidad. Su deficiencia se asocia con enfermedades autoinmunitarias y alergias, y su aumento se
relaciona con el cáncer. La manipulación de las Treg es un objetivo de los estudios de inmunología del cáncer, debido a los potenciales efectos antitumorales.
Las células Treg se producen en el timo y en la periferia. La radiación ultravioleta es capaz de suprimir la respuesta inmunitaria en la piel, entre otros mecanismos, por la inducción de las Treg, y esto se asocia al desarrollo de cáncer de
piel melanoma y no melanoma.
En este artículo se revisan los aspectos esenciales de las células Treg, su relación con la radiación ultravioleta y el cáncer, específicamente el cáncer de piel
melanoma y no melanoma.
