Dr. Nicola has more than 20 years of experience studying the cell biology of herpes simplex virus glycoproteins and entry, and is perhaps best known for revealing that herpes viruses utilize low pH, endocytic pathways to enter and infect biologically relevant cells. This finding conflicted with the long-held dogma that herpes viruses were a paradigm for viruses that enter solely by direct fusion with the plasma membrane. However, over a short period of time, these findings were integrated into the field, and it was recognized that other herpes viruses including human cytomegalovirus, Kaposi’s sarcoma herpes virus and varicella zoster virus utilize similar pathways. In addition to pH-triggered entry, the Nicola lab also investigates the proteasome-dependent delivery of HSV capsids to the nucleus during entry. We utilize a combination of cellular, molecular, biochemical, and microscopic approaches to delineate the step-by-step itinerary of the incoming virus. A better understanding of how herpes simplex virus interacts with the cell will identify novel targets for intervention.
