Peptides corresponding to the heptad repeat motifs in the transmembrane protein (gp41) of human immunodeficiency virus type 1 elicit antibodies to receptor-activated conformations of the envelope glycoprotein

Abstract

Two heptad repeat regions in the ectodomain of the human immunodeficiency virus type 1 (HIV-1) transmembrane subunit (gp41) self-assemble into a six-helix bundle structure that is critical for virus entry. Immunizations with peptides corresponding to these regions generated antibodies specific to the receptor-activated conformations of gp41.
