Abstract
T cell memory depends on factors that regulate expansion and death of these cells after antigenic stimulation. Mice deficient in perforin and interferon-γ (IFN-γ) exhibited increased expansion, altered immunodominance, and decreased death of antigen-specific CD8 + T cells after infection with an attenuated strain of Listeria monocytogenes , which was cleared from these mice. Expansion of CD8 + T cells was controlled by perforin, whereas IFN-γ regulated immunodominance and the death phase. Thus, perforin and IFN-γ regulate distinct elements of CD8 + T cell homeostasis independently of their role as antimicrobial effector molecules.

- Attenuated LM strain DP-L1942 (ActA-deficient) (3) was prepared for injection and colony forming units (CFU) per spleen or per grams of liver were determined as previously described (4).
- The magnitude of the epitope-specific CD8 + T cell response was determined by ICS for TNF IFN-γ or MHC class I tetramer staining as previously described (5 11 15). For ICS the percent of TNF + or IFN-γ + CD8 + T cells in the unstimulated sample for each mouse was subtracted from the peptide stimulated value to determine the frequency of Ag-specific CD8 + T cells. Total number of epitope-specific CD8 + cells per spleen was calculated from this frequency the percent of CD8 + T cells in each sample and total number of cells per spleen.

LLO 91-99 and OVA 323-336 peptides (1 μM final concentration) were added for the last 24 hours of culture.
