KLRG1 and infection: We found that the frequency of NP+CD8+ T cells in the lung and spleen was similar between Brd7fl/fl mice and Brd7ΔT mice (Figure 2F), while a reduction of antigen-specific KLRG1+IL-7R– SLECs was found in the Brd7ΔT mice after infection with HKx31 viruses of previously PR8-primed mice (Figure 2G).
