David Thompson

Professor Purdue University

David H. Thompson is a Professor of Organic Chemistry at Purdue University. His current research is focused on [1] the development of bioresponsive self-assembling materials for targeted delivery of nucleic acid therapeutics that merge supramolecular and organic reaction mechanism concepts, and [2] the continuous synthesis of active pharmaceutical ingredients using telescoped flow chemistry techniques. His earlier work with nucleic acid delivery using low pH-activated lipids (Pharm. Res. 2002), polyrotaxanes (Mol. Pharm. 2013), and degradable polymers (Macromolecules 2018) ultimately led to the development of a targeted layer-by-layer elastin-like polypeptide nucleic acid nanoparticle (LENN) system derived from biomanufacturable components that displays efficient delivery activity in vitro and in vivo.

Optimizing mRNA Delivery with Targeted Elastin-Like Polypeptide-Based LENN Formulations
12:00 pm
  • LENN comprised of elastin-like polypeptide-epidermal growth factor fusion proteins (ELP-EGF) and cyclodextrin-peptide conjugates form stable mRNA complexes that efficiently deliver their cargo to the cytosol of EGFR+ bladder tumor cells in vitro and in vivo
  • Multiple reaction monitoring HPLC-MS lipidomics analysis, pharmacologic inhibition, and EGF blockade experiments indicate that EGF-bearing mRNA LENN enter EGFR+ cells via clathrin-mediated endocytosis, with no significant changes to other lipid pathways that would indicate off-target effects or immune responses
  • Addition of 10% glycerol and lyophilization enables the long-term storage of mRNA LENN complexes, with full retention of activity after rehydration
