ABSTRACT
El vitíligo es un trastorno pigmentario en el que se ha evidenciado el estrés oxidativo como parte de la patogenia. Se conocen vías encargadas de proteger a los melanocitos del daño causado por las especies reactivas de oxígeno, como por ejemplo la vía del factor nuclear eritroide similar al factor 2 (Nrf2). El Nrf2 es un factor de transcripción que cuando el organismo se encuentra en homeostasis permanece inhibido, pero en presencia de estrés oxidativo permite la codificación de enzimas antioxidantes de fase ii. En el vitíligo se evidencian anomalías en la localización y función del Nrf2, así como polimorfismos que aumentan el riesgo de esta enfermedad. Así mismo, se han investigado múltiples moléculas que actúan en el Nrf2 buscando encontrar tratamientos emergentes útiles para el vitíligo. Se realizó una búsqueda de artículos en español e inglés en las bases de datos PubMed, Ovid, Scopus y Web of Science Clarivate, utilizando las palabras clave «Vitiligo AND nuclear factor erythroid derived 2 like 2 OR NRF2» sin restricción de tiempo. Se incluyeron todos los estudios in vitro, revisiones narrativas, series de casos, estudios de cohorte y ensayos clínicos aleatorizados y no aleatorizados que abordaban específicamente el tema del Nrf2 asociado a vitíligo
Vitiligo is a pigmentary disorder, in which oxidative stress has been evidenced as part of the pathogenesis. Pathways responsible for protecting melanocytes from damage caused by reactive oxygen species are known as the nuclear factor erythroid factor 2 (Nrf2) pathway. Nrf2 is a transcription factor that remains inhibited when the organism is in homeostasis, but in the presence of oxidative stress it allows the encoding of phase ii antioxidant enzymes. In vitiligo there are abnormalities in the location and function of Nrf2 as well as polymorphisms that increase the risk of this disease. Currently, multiple molecules that act on Nrf2 have been investigated in order to find useful emerging treatments for vitiligo. A search for articles in Spanish and English was carried out in the PubMed, Ovid, Scopus and Web of Science Clarivate databases, using the keywords Vitiligo AND nuclear factor erythroid derived 2 like 2 OR NRF2 without time restriction. All in vitro studies, narrative reviews, case series, cohort studies, and randomized and non-randomized clinical trials that specifically addressed the issue of Nrf2 associated with vitiligo were included (AU)
