Protein Chemistry and Cell Biology
Research in the Pellois lab is currently focused on the following topics:
- development of reagents that can deliver macromolecules into live cells efficiently and safely
- use of such delivery approaches to deliver proteins into live cells so as to manipulate and investigate cellular processes
- development of peptide-based photosensitizers for the light-induced inactivation of drug-resistant bacteria
- elucidation of the mechanisms by which cells communicate with one another by sharing material via vesicle secretion and internalization
- mapping of intracellular protein-protein interactions and impact of viral protein mutations on virus/host responses
Each of these projects involves a combination of chemistry, biochemistry and cell biology. We typically investigate cellular processes at a molecular level and design new tools to study such processes. We use a wide variety of techniques, including protein engineering, peptide chemistry, molecular cloning, and live cell fluorescence microscopy.
