Elimination of HIV-1-infected cells by broadly neutralizing antibodies.
The Fc region of HIV-1 Env-specific broadly neutralizing antibodies (bNAbs) is required for suppressing viraemia, through mechanisms which remain poorly understood. Here, we identify bNAbs that exert antibody-dependent cellular cytotoxicity (ADCC) in cell culture and kill HIV-1-infected lymphocytes through natural killer (NK) engagement. These antibodies target the CD4-binding site, the glycans...
متن کاملNon-Neutralizing Antibodies Directed against HIV and Their Functions
B cells produce a plethora of anti-HIV antibodies (Abs) but only few of them exhibit neutralizing activity. This was long considered a profound limitation for the enforcement of humoral immune responses against HIV-1 infection, especially since these neutralizing Abs (nAbs) are extremely difficult to induce. However, increasing evidence shows that additional non-neutralizing Abs play a signific...
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 کاملHIV vaccine development and broadly neutralizing antibodies
Human immunodeficiency virus-1 (HIV-1) infects about 35 million people worldwide [1]. There is no vaccine in current clinical use. Although available drug treatments are generally effective in controlling infection, they are not curative, can cause significant side effects and are unable to prevent comorbidities such as cardiovascular disease and cancers. In 2012, about 1.6 million people world...
متن کاملbNAber: database of broadly neutralizing HIV antibodies
The discovery of broadly neutralizing antibodies (bNAbs) has provided an enormous impetus to the HIV vaccine research and to entire immunology. The bNAber database at http://bNAber.org provides open, user-friendly access to detailed data on the rapidly growing list of HIV bNAbs, including neutralization profiles, sequences and three-dimensional structures (when available). It also provides an e...
