(627g) A Crowdsourced Understanding of Functionally Potent Antibodies (Invited Speaker)

Antibodies act as a nexus between innate and adaptive immunity: they provide a means to target the potent toxic activities of a spectrum of innate immune effector cells in order to clear viral particles and infected cells. This functional landscape is remarkably complex, with multiple antibody variants directed to multiple epitopes on multiple viral antigens. This diversity of viral recognition characteristics is further complemented by diversity in each antibody’s ability to recruit the potent anti-viral effector functions of a suite of innate immune effector cells such as Natural Killer cells and phagocytes. Results from both human and animal model studies have implicated these effector functions in vaccine-mediated protection, but the complexity of these activities has challenged traditional methods of evaluating antibody responses. We demonstrate how high-throughput, high-content platforms for the biophysical and functional interrogation of the innate immune recruiting capacity of diverse virus-specific antibodies are capable of parsing this complex molecular landscape into components that can be used to develop computational models of antibody activity and provide insights into mechanisms of vaccination and new prospects for engineering innovative antibody therapies. This talk will focus on insights resulting from applying artificial intelligence to learn from humoral immune profiles to better understand mechanisms of antibody-mediated protection from infectious disease.
