Title: Immunization of macaques with soluble HIV type 1 and influenza virus envelope glycoproteins results in a similarly rapid contraction of peripheral B cell responses after boosting
Abstract: The envelope glycoproteins (Env) represent a critical component of a successful antibody-mediated human immunodeficiency virus type 1 (HIV-1) vaccine. However, immunization with soluble Env was reported to induce short-lived antibody responses, suggesting that Env has unusual immunogenic properties. Here, we directly compared the magnitude and durability of B-cell responses induced by HIV-1 Env and an unrelated soluble viral protein, influenza virus hemagglutinin (HA), in simultaneously inoculated macaques. We demonstrate robust peak responses followed by rapid contraction of circulating antibody and memory B cells for both antigens, suggesting that short-lived responses are not unique to HIV-1 Env but may be a common feature of soluble protein vaccines.
