The B cell subsets and protective functions of antibodies that underlie immune-control of HIV-1 infection and vaccine-induced immunity are poorly characterised. This thesis demonstrated that early control of HIV-1 infection was associated with the magnitude of opsonising IgG antibodies that induced phagocytosis of HIV-1 p24 capsid protein by plasmacytoid dendritic cells. The B cell compartment following vaccination was also examined using novel methodology developed here. The quality of vaccine-induced antibody responses was associated with the expansion of phenotypically distinct B cell, plasmablast and circulating follicular helper T cell subsets. These findings have important implications for the rational design of vaccines.
