El HIV/SIDA afecta a más de 40 millones de personas en todo el mundo. Los altos costos de los antiretrovirales, y la resistencia a estos fármacos han obligado a la búsqueda de nuevas moléculas bioactivas enfocadas a bloquear proteínas celulares o virales, o moléculas que participen en el ciclo de replicación del virus, y que permitan aumentar la supervivencia y la calidad de vida de las personas infectadas. Recientemente se describieron ciertos factores celulares con actividad anti-VIH-1, los cuales por sus características, constituyen una familia de proteínas celulares conocidas como APOBEC. Los miembros de esta familia son enzimas deaminasas que modifican citosinas por uracilos en DNA/RNA celulares o extraños. La subfamilia de proteínas APOBEC3 es la más estudiada, ya que está implicada en la respuesta inmune innata, es decir, presentan actividad antiviral contra diferentes virus, entre ellos, el HIV-1. APOBEC3, no sólo es capaz de editar el genoma viral, sino que participa en diferentes etapas del ciclo replicativo. En esta revisión se discuten hasta donde es posible, los diferentes mecanismos en los cuales esta subfamilia de proteínas participa activamente en la respuesta antiviral, mediante la inhibición de la replicación de virus.Downloads
