Elicitation of Neutralizing Antibodies with DNA Vaccines Expressing Soluble Stabilized Human Immunodeficiency Virus Type 1 Envelope Glycoprotein Trimers Conjugated to C3d

Abstract excerpt

DNA vaccines expressing the envelope (Env) of human immunodeficiency virus type 1 (HIV-1) have been relatively ineffective at generating high-titer, long-lasting immune responses. Oligomeric or trimeric (gp140) forms of Env that more closely mimic the native proteins on the virion are often more effective immunogens than monomeric (gp120) envelopes. In this study, several forms of Env constructed from the HIV-1...
