چکیده

RESUMEN Las citocinas, las quimiocinas y sus receptors son probablemente los principales factores del huésped que influyen en la patogénesis del VIH-1 in vivo. La infección por el VIH-1 estimula la producción de citocinas y quimiocinas en una gran variedad de tipos celulares. Estos factores pueden inducir o inhibir la replicación viral. Además, algunos receptores de quimiocinas actúan como co-receptores necesarios para la entrada viral en la célula, y el nivel de disponibilidad de dichos co-receptores determina la susceptibilidad de la infección. Tanto las citocinas como las quimiocinas modulan la expresión de los co-receptores. En esta revisión, describimos la importancia de la distribución de las quimiocinas y de sus receptores en la infección primaria y en la posterior evolución de la enfermedad; también describimos el efecto de las citocinas más relevantes en la replicación viral y en la regulación de la homeostasis inmunitaria. Finalmente, discutimos el uso de las citocinas y las quimiocinas como agentes terapéuticos.
