Dr. Spector's lab has spent over 30 years studying human cytomegalovirus (HCMV), which is the major viral cause of birth defects, a serious problem in immunocompromised individuals, and a risk factor in atherosclerosis. Her research centers on viral pathogenesis and the molecular mechanisms used by HCMV to control its gene expression and subvert the cell's signaling and regulatory pathways. A key discovery was that HCMV modulates the ubiquitin- proteasome pathway by inactivating the anaphase promoting complex, the major E3 ubiquitin ligase in cell cycle regulation. Other areas of research include the role of HCMV in atherosclerosis and the effects of HCMV infection on the neural lineage specification and maturation of stem and progenitor cells.
Dr. Spector's group has also developed a novel strategy for vaccines against viruses that persist and establish latency, and has shown their protective efficacy in animal models of cytomegalovirus infection and genital HSV-2 infection. The underlying principle is that herpesviruses persist because natural immunity cannot eliminate the infected cells, and thus vaccination must be more effective in establishing protection than natural infection.
