Role Of The Human Cytomegalovirus Ie2 Protein On Transcriptional Regulation Of Viral Promoters, Siabhon Michelle Harris
Role Of The Human Cytomegalovirus Ie2 Protein On Transcriptional Regulation Of Viral Promoters, Siabhon Michelle Harris
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 …
Study Of The Dna Damage Complexes Within The Htlv-1 Tax Oncoprotein Interactome, Sidi Mehdi Belgnaoui

Theses and Dissertations in Biomedical Sciences
Human T-cell leukemia virus type 1 (HTLV-1) is a transforming retrovirus that can give rise to adult T-cell leukemia (ATL) and HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). Tax is a virally encoded oncoprotein that is involved in HTLV-1 mediated cellular transformation. It has been hypothesized that Tax induces genomic instability via repression of the cellular DNA damage repair response. Our laboratory has previously shown that the interaction between Tax and various proteins involved in the DNA-damage response pathway impairs the ability of these proteins to mount an efficient repair response. As part of these observations, we proposed that Tax induces …

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, …
Comparison Of Immune Correlates, Age Related Changes And Proteomic Profiling Of Healthy Individuals Receiving Influenza Vaccines, Gaurav Basu
Theses and Dissertations in Biomedical Sciences
The burden of influenza related infections is substantial, both in terms of illness, lives lost and economic impact on society. The degree of impact of influenza related infections is much higher in the elderly population where it is a leading cause of catastrophic disability; greatly affecting the quality of life of elderly persons above 65 years of age. Vaccination is the mainstay for control and prevention of influenza infections. There are two vaccine formulations that are licensed for use at present. The inactivated influenza vaccines (TIIV) which have been used for 60 years in all age groups and the new …
