title: Spectral and sequence similarity between vasoactive intestinal peptide and the second conserved region of human immunodeficiency virus type 1 envelope glycoprotein (gp120): possible consequences on prevention and therapy of AIDS.
abstract: Recently, in sera of HIV infected individuals, antibodies recognizing nonimmunogenic C-terminal domain of the second conserved region of HIV-1 gp120 were identified (1). These antibodies are significantly more prevalent in asymptomatic carriers than in AIDS patients (1). Here we reported striking spectral and sequence homologies between human vasoactive intestinal peptide (VIP) and the conserved peptide derived from HIV-1 gp120 which binds these antibodies. The possible consequences of these findings on therapy and prevention of AIDS are discussed.
