Feline Lentivirus: Molecular Analysis And Epidemiology In Southern African Lions, Hayley Rebecca Adams

Doctoral Dissertations

Feline immunodeficiency virus is a retrovirus of domestic cats causing significant lifelong infection. Infection has also been detected in nondomestic species, including African lions. It is endemic in certain populations in east and southern Africa. Infection leads to immunologic dysfunction and immunosuppressive disease in domestic cats; however, little research exists about the pathogenic effects of infection in lions and its epidemiological impact on free-ranging and captive populations. Little is known about the lentivirus in these populations at the molecular and host level. Analysis of the virus from these populations is necessary for development of detection assays that are both sensitive …

Systemic And Mucosal Infection Program Protective Memory Cd8 T Cells In The Vaginal Mucosa., Thandi M. Onami, P. K. Suvas, H. M. Dech, J. Zeng

Whether mucosal immunization is required for optimal protective CD8 T cell memory at mucosal surfaces is controversial. In this study, using an adoptive transfer system, we compare the efficacy of two routes of acute lymphocytic choriomeningitis viral infection on the generation, maintenance, and localization of Ag-specific CD8 T cells in tissues, including the vaginal mucosa. Surprisingly, at day 8, i.p. infection results in higher numbers of Ag-specific CD8 T cells in the vaginal mucosa and iliac lymph node, as well as 2-3x more Ag-specific CD8 T cells that coexpress both IFN-gamma and TNF-alpha in comparison to the intranasal route of …
