Peptides for treatment of HIV infection

   
   

The HIV-1 envelope protein gp120 is toxic to rodent and human neurons by indirect mechanisms requiring accessory glial cells. Chemokines are known to block gp120 interactions with chemokine receptors on T cells, macrophanges, and microglia, thereby preventing viral infection. Gp120-induced neuronal killing in rat hippocampal cultures was partially or completely prevented by a specific short peptides related to chemokines, specially IKEYFTS (SEQ. ID NO: 2) and LESYT (SEQ. ID NO: 1). These peptides thus have use in the treatment of neurological degenerative diseases having symptoms associated with neuronal cell death.

Chemokines se conoce para bloquear las interacciones gp120 con los receptores del chemokine en las células de T, macrophanges, y microglia, de tal modo previniendo la infección viral. La matanza neuronal de Gp120-induced en culturas hippocampal de la rata estaba parcialmente o prevenido totalmente por los peptides cortos específicos se relacionaron con los chemokines, especialmente IKEYFTS (SEQ. ID NO: 2) y LESYT (SEQ. ID NO: 1) Estos peptides tienen así uso en el tratamiento de las enfermedades degenerativas neurológicas que tienen síntomas asociados a muerte neuronal de la célula.
