From: Differential impact of ageing on cellular and humoral immunity to a persistent murine γ-herpesvirus
Virus-specific CD8 T cell numbers are maintained with age. Mice were bled at various times following γHV68 infection and virus specific CD8 T cells were detected using MHC class I tetramer staining and flow cytometry. Symbols represent the frequency of ORF6487-495 (p56, upper panel) and ORF61524-531 (p79, lower panel) specific cells among CD44high CD8+ T cells found in the peripheral blood of individual mice at the indicated times post infection.
