项目摘要
The goal of this Core is to establish novel single cell technology to analyze specific plasmablasts during
an ongoing immune response to SIV vaccinafion or infecfion in rhesus macaques. We will generate detailed
informafion about the dynamics, immunoglobulin isotype useage and phenotype of the plasmablast
responses induced both at a systemic level as well as at mucosal sites, and determine how these responses
are modulated by the use of different adjuvants. The single cell analysis will allow us to interrogate the
immunoglobulin repertoire of the ongoing response, identify the specific epitopes targetted by the
plasmablasts and define the affinity/avidity ofthe indivdual anfibodies against their antigen. Furthermore we
will characterize the funcfional propoerties ofthe isolated antibodies with regards to neutralizafion, breadth of
neutralizafion as well as non-neutralizing, antibody mediated cytolyfic mechanisms. Furthermore, particularly
interesting monoclonal antibodies, i.e. broadly neutralizing, might also be excellent candidates for future
passive transfer experiements in rhesus macaques and also have implicafions for therapy and vaccine
design for HIV in humans.
