Description
Summary:Antiviral innate mechanisms have a potential use in developing preventive and therapeutic strategies against HIV Specifically, antiviral soluble factors have been evaluated in multiple investigations, based on their capacity to inhibit different steps of the viral cycle, and to increase the host immune response. Among these factors, TRIM-5α, APOBEC3G, SAMHD1, ELAFIN, SERPINA1 and SLPI are of particular interest, as they can act directly on the viral particle or the cell, or promote the production of molecules related to the viral immune response. Some of these factors have been associated with a low risk of HIV infection or slow progression to AIDS. Evaluation of mechanisms exhibited by antiviral proteins is a requirement for developing new therapeutic alternatives. KEYWORDS Acquired Immunodeficiency Syndrome: Antivirals: HIV: Immunity Viral Replication: Viral Proteins Los mecanismos innatos antivirales han resultado de gran interes debido a su uso potencial para la prevencion y tratamiento de la infeccion por el VIH. En particular, los factores solubles antivirales han sido objeto de multiples investigaciones por su capacidad de inhibir diferentes pasos del ciclo replicativo viral y de potenciar la respuesta inmune del hospedero. Entre estos factores solubles se destacan TRIM-5α. APOBEC3G, SAMHD1. ELAF1N, SERPINA1 y SLPI. que actuan directamente sobre la particula viral o la celula, o promueven la produccion de moleculas involucradas en la respuesta inmune contra el virus. Algunos de ellos se han correlacionado con un bajo riesgo de adquirir la infeccion por el VIH o con una lenta progresion a sida. La exploracion de los mecanismos antivirales de estas proteinas es requisito para el desarrollo de nuevas alternativas terapeuticas.
