Theses and Dissertations in Biomedical Sciences
Human cytomegalovirus (HCMV) is a ubiquitous pathogen able to cause severe mortality and morbidity in immuno-compromised individuals. Successful infection by HCMV is dependent on expression of viral genes essential for replication. Immediate early (IE) gene products are the first subset of viral genes to be expressed during infection and function as key transcriptional regulators. IE2 is one the most predominantly expressed IE proteins and is essential for HCMV infection. IE2 transactivates several viral promoters, including those of the essential viral DNA polymerase (UL54) and UL112-113 gene regions. IE2 is also able to autoregulate is own expression and repress expression of …

Human cytomegalovirus (HCMV) is a ubiquitous herpesvirus that causes significant morbidity and mortality in the immune compromised. Using the mutine cytomegalovirus (MCMV) model, we identified two genes, M140 and M141, which are determinants of macrophage tropism. Monocytes/macrophages are a critical cell type for cytomegalovirus (CMV) pathogenesis as sites of viral latency and by supporting viral replication and disseminating virus throughout the body. We previously found that the localization of the M140/M141 gene products (pM140/pM141) is different when the proteins are co-expressed as compared to their individual expression. When the proteins are individually expressed pM141 localizes diffusely throughout the cytoplasm and, …
