Summary

Rock Mancini, a synthetic organic chemist, presents his research journey from stabilizing proteins with trehalose polymers to developing temperature-responsive vaccine adjuvants and exploring chaokosmotropic polymers for biocatalysis. He begins with his PhD work on polymerizing trehalose to create glycopolymers that stabilize enzymes against heat and freeze-thaw. He then moves to his independent career in synthetic immunology, where he developed small molecule immunotherapeutics for cancer. The core of the talk focuses on creating vaccine adjuvants that attenuate activity in response to fever by copolymerizing a trehalose-based adjuvant with poly(N-isopropylacrylamide) (PNIPAM), which has a lower critical solution temperature (LCST) near body temperature. He shows that above the LCST, the polymer sequesters the lipid tail of the adjuvant, reducing immune activation. In vivo studies in an influenza vaccine model show that the polymer adjuvant is as protective as alum. Finally, he discusses preliminary work on chaokosmotropic polymers, which combine chaotropic (PNIPAM) and kosmotropic (trehalose) monomers, and their potential to enhance enzyme activity and stability. He presents data showing that these polymers increase alkaline phosphatase activity and stability at high temperatures. The talk concludes with open questions and a call for collaboration.
