Dr. Pellett's research is aimed at understanding the biology of human herpesviruses and improving clinical outcomes of herpesvirus infections. He studies how human cytomegalovirus (HCMV) remodels cells it infects, transforming them into factories that can produce an infectious virus. HCMV is the leading cause of congenitally-acquired cerebral palsy and deafness, and an important cause of mental retardation, seizures, blindness and death. One in 150 children is born with the virus, and one in 750 is born with or will develop permanent disabilities caused by congenital HCMV.
Herpesviruses: Molecular Marvels and Potent Pathogens
Of the human herpesviruses, HCMV has the greatest clinical impact. It is a leading cause of congenitally acquired mental retardation and deafness, is a major pathogen in immunocompromised patients, and may contribute to the development of atherosclerosis and other inflammation-linked vascular diseases. We are engaged in basic studies of the molecular and cellular biology of HCMV, as well as in clinically oriented translational research.
HCMV Molecular and Cellular Biology
Cell biology of HCMV virion assembly. Human cytomegalovirus induces profound changes in infected-cell morphology, including formation of large cytoplasmic inclusions that correspond to the virion assembly complex (AC). We found that the AC is arranged such that Golgi- and trans-Golgi-derived vesicles are at the outer periphery of the AC and early endosome-derived vesicles are at its center. This counterintuitive arrangement nonetheless allows for a conventional order of membrane-protein biosynthesis and transport. The resulting model of AC structure suggests a mechanism by which the virus can regulate the order of tegument assembly. We have identified three HCMV genes that are important for cVAC biogenesis and are studying their mechanisms of action.
The Translational Research component of our program has involved multidisciplinary collaboration between basic laboratory scientists, clinical virologists, immunologists, infectious disease specialists, epidemiologists, and biostatisticians. We have examined the pathogenic role of herpesviruses in immunocompromised patients, and developed numerous methods for diagnosis of herpesvirus infections.
