Role Of Atm In T Cell Dysfunction During Chronic Viral Infections, Juan Zhao
Role Of Atm In T Cell Dysfunction During Chronic Viral Infections, Juan Zhao
Electronic Theses and Dissertations
Hepatitis C virus (HCV) or human immunodeficiency virus (HIV) infection leads to a phenomenon of inflammaging, in which chronic infection or inflammation induces an immune aged phenotype with T cell dysfunction. Thus, HCV or HIV infection has been deemed as a model to study the mechanisms of T cell infammaging and viral persistence in humans. In this dissertation, T cell homeostasis, DNA damage and repair machineries were investigated in patients with chronic HCV or HIV infection at risk for inflammaging. We found a significant depletion in CD4 T cells, which was correlated with their apoptosis in chronically HCV/HIVinfected patients, compared …

Senecavirus A: Pathogenicity And Interactions With Host Cell Death Pathway, Maureen Hoch Vieira Fernandes
Electronic Theses and Dissertations
Senecavirus A (SVA) is a positive sense single-strand RNA virus of the genus Senecavirus, family Picornaviridae. Senecavirus A is an emerging picornavirus of swine, which causes vesicular disease (VD) in pigs that is clinically indistinguishable from footand- mouth disease and other high consequence VDs of swine. There is evidence that SVA has been circulating in the US swine population since the late eighty’s, however, recently the virus emerged worldwide, and it has been associated with several VD outbreaks in pigs in many of the major swine producing countries. Despite the recent surge in the number of cases of …
