Attrition Of Cd8 T Cells During The Early Stages Of Viral Infections: A Dissertation, Kapil Bahl Jan 2008

Attrition Of Cd8 T Cells During The Early Stages Of Viral Infections: A Dissertation, Kapil Bahl

GSBS Dissertations and Theses

Profound lymphopenia has been observed during many acute viral infections, and our laboratory has previously documented a type 1 IFN-dependent loss of most memory (CD44hi) and some naïve (CD44lo) CD8 T cells immediately preceding the development of the antiviral T cell response at days 2-4 following lymphocytic choriomeningitis virus (LCMV) infection. In this thesis, I will examine additional mechanisms involved in the early attrition of CD8 T cells and evaluate whether antigen-specific and non-specific CD8 T cells are equally susceptible. Lastly, I will examine whether the early attrition of CD8 T cells contributes to the generation of an ...
