Abstract
Potent broadly neutralizing antibodies (bNAbs) targeting HIV-1 exhibit significant antiviral activity in humans. Recent advances have demonstrated that novel antibodies and bNAb combinations can effectively restrict the development of viral escape mutations. Moreover, passive immunization trials have provided proof-of-principle for bNAb-mediated prevention of infection with antibody-sensitive HIV-1 strains. In contrast, clinical studies investigating the activity of HIV-1 bNAbs on the latent reservoir failed to demonstrate substantial effects. Clinical adoption of HIV-1 bNAbs will require the development of more potent and broadly active antibodies as well as their implementation in optimized strategies to fully harness the capabilities of bNAbs. We review preclinical and clinical studies on HIV-1 bNAbs to highlight their potential and remaining limitations.
期刊介绍:
Current Opinion in Virology (COVIRO) is a systematic review journal that aims to provide specialists with a unique and educational platform to keep up to date with the expanding volume of information published in the field of virology. It publishes 6 issues per year covering the following 11 sections, each of which is reviewed once a year: Emerging viruses: interspecies transmission; Viral immunology; Viral pathogenesis; Preventive and therapeutic vaccines; Antiviral strategies; Virus structure and expression; Animal models for viral diseases; Engineering for viral resistance; Viruses and cancer; Virus vector interactions. There is also a section that changes every year to reflect hot topics in the field.
