PURPOSE OF REVIEW: The ability to induce broadly neutralizing antibody (bNAb)
responses is likely essential for development of a globally effective HIV
vaccine. Unfortunately, human vaccine trials conducted to date have failed to
elicit broad plasma neutralization of primary virus isolates. Despite this
limitation, in-depth analysis of the vaccine-induced memory B-cell repertoire can
provide valuable insights into the presence and function of subdominant B-cell
responses, and identify initiation of antibody lineages that may be on a path
towards development of neutralization breadth. RECENT FINDINGS: Characterization
of the functional capabilities of monoclonal antibodies isolated from a HIV-1
vaccine trial with modest efficacy has revealed mechanisms by which
non-neutralizing antibodies are presumed to have mediated protection. In
addition, B-cell repertoire analysis has demonstrated that vaccine boosts shifted
the HIV-specific B-cell repertoire, expanding pools of cells with long third
heavy chain complementarity determining regions - a characteristic of some bNAb
lineages. SUMMARY: Detailed analysis of memory B-cell repertoires and evaluating
the effector functions of isolated monoclonal antibodies expands what we can
learn from human vaccine trails, and may provide knowledge that can enable
rational design of novel approaches to drive maturation of subdominant disfavored
bNAb lineages.
