Discovery Park Distinguished Lecture Series

Discovery Park Distinguished Lecturer: Arup K. Chakraborty, How to Hit HIV Where it Hurts

April 26, 2018
4:00 PM - 5:30 PM
Burton D. Morgan Center, Room 121

Description

Vaccination has saved more lives than any other medical procedure. But, some pathogens have evolved which have defied successful vaccination using the empirical paradigms pioneered by Pasteur and Jenner. Professor Chakraborty will describe how bringing together theoretical/computational approaches from physics and engineering, especially statistical mechanics, with immunology is beginning to confront this challenge by developing some of the principles necessary for rational design of vaccines that may eliminate these scourges. One characteristic of many pathogens for which successful vaccines do not exist is that they present themselves in various guises. HIV is an extreme example because of its high mutability, and it continues to wreak havoc, especially in developing countries. He will describe the development of models to translate data on HIV protein sequences to knowledge of the HIV fitness landscape, and tested the resulting predictions against in vitro and clinical data (with collaborators). Based on these studies, a therapeutic T cell-based vaccine was designed, which is now being advanced to pre-clinical studies in monkeys. He will also describe work pertinent to how vaccination may induce broadly neutralizing antibodies that can neutralize diverse HIV strains –this work lies at a crossroad of immunology, evolutionary biology, and statistical physics.
