Recent Progress toward Engineering HIV-1-Specific Neutralizing Monoclonal Antibodies
The recent discoveries of broadly potent neutralizing human monoclonal antibodies represent a new generation of antiretrovirals for the treatment and prophylaxis. Antibodies are generally considered more effective and safer and have been proved to provide passive protection against mucosal challenge in humanized mice and macaques. Several neutralizing Abs could protect animals against HIV-1 but...
متن کاملNeutralizing cross-reactive and non-neutralizing monoclonal antibodies to HIV-1 gp120.
Amino acid sequences inducing neutralizing antibodies to HIV-1 were sought. Murine monoclonal antibodies (MAbs) were characterized by their reactivity with the envelope precursor gp160 or the Escherichia coli recombinant DNA products pB1 and pE3 representing the carboxy- and amino-terminal halves of mature envelope gp120. Fine mapping of the MAb determinants was performed using defined 15-mer s...
متن کاملCross-reactive HIV-1-neutralizing human monoclonal antibodies identified from a patient with 2F5-like antibodies.
The genes encoding broadly HIV-1-neutralizing human monoclonal antibodies (MAbs) are highly divergent from their germ line counterparts. We have hypothesized that such high levels of somatic hypermutation could pose a challenge for elicitation of the broadly neutralizing (bn) Abs and that identification of less somatically mutated bn Abs may help in the design of effective vaccine immunogens. I...
متن کاملBroadly neutralizing antibodies to prevent HIV-1.
A dvances in technology—especially single-cell antibody cloning techniques—have led to the isolation and characterization of antibodies from people with HIV infection that can neutralize many variants (1). These are referred to as broadly neutralizing antibodies (bnAbs). Such antibodies can be detected in about 25% of persons with untreated HIV-1 infection (2), reflecting a host immune response...
متن کاملTailored Immunogens Direct Affinity Maturation toward HIV Neutralizing Antibodies
Induction of broadly neutralizing antibodies (bnAbs) is a primary goal of HIV vaccine development. VRC01-class bnAbs are important vaccine leads because their precursor B cells targeted by an engineered priming immunogen are relatively common among humans. This priming immunogen has demonstrated the ability to initiate a bnAb response in animal models, but recall and maturation toward bnAb deve...
