Herpesviruses: Molecular Marvels and Potent Pathogens
Dr. Pellett's research is aimed at understanding the biology of human herpesviruses and improving clinical outcomes of herpesvirus infections, with a focus on human cytomegalovirus (HCMV). Of the human herpesviruses, HCMV has the greatest clinical impact. It is a leading cause of congenitally acquired cerebral palsy and deafness, and is a major pathogen in immunocompromised patients. 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. Dr. Pellett studies how HCMV remodels cells it infects, transforming them into factories that can produce infectious virus.
Cell biology of HCMV virion assembly:
HCMV induces profound changes in infected-cell morphology, including formation of large cytoplasmic inclusions that correspond to the cytoplasmic virion assembly complex (cVAC). We found that the cVAC is arranged such that Golgi- and trans-Golgi-derived vesicles are at the outer periphery of the cVAC 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. We are also working to elucidate the pathway taken by nascent virions as they are enveloped and then transported to the plasma membrane for release.
