Major Areas of Research
- Development of vaccines against human herpesviruses
- Identification of cellular variants in patients with severe herpesvirus infections
- Pathogenesis of human virus infections in vitro and in vivo
- Identification of cellular proteins important for entry of herpesviruses into cells
We study the molecular genetics, pathogenesis, and clinical aspects of human herpesviruses, including Epstein-Barr virus (EBV), herpes simplex virus (HSV), varicella-zoster virus (VZV), and cytomegalovirus (CMV). The laboratory focuses on vaccine development, cellular proteins important for virus entry and replication, and identification of cellular mutations in patients with severe herpesvirus infections. Recent findings include development of candidate vaccines for HSV and EBV; identification of cellular genes that predispose to severe EBV infections; and novel entry mediators for CMV and VZV.
Clinical projects complement the laboratory studies. These include a Phase I study of a replication defective herpes simplex virus vaccine, studies of patients with severe virus infections to define genetic variants associated with the disease, studies of patients with EBV diseases, a respiratory syncytial virus challenge study, and attempts to identify novel viruses in patients with unexplained syndromes.
Dr. Cohen received his M.D. from The Johns Hopkins University and was a resident in medicine at Duke University. Following a medical staff fellowship at the National Institutes of Health (NIH), he was a clinical fellow in infectious diseases at the Brigham and Women’s Hospital and an instructor in medicine at Harvard University. He returned to NIH, where he was the chief of the Medical Virology Section in the Laboratory of Clinical Infectious Diseases until 2010. In June 2010, Dr. Cohen became chief of the Laboratory of Infectious Diseases.
