FIGURE 9.
Circulating serum IgG Ab GMTs were attenuated in SDRMEM mice only during resting memory. Retro-orbital blood samples were taken at 6+ weeks postprimary A/PR/8/34 infection and during homologous rechallenge. Circulating serum anti-influenza IgG Ab was assessed by ELISA (n = 10–20 per group). During resting memory, SDR-MEM mice had a >4-fold decrease in raw titer, and the 95% CI for the GMT was discordant from that of the SDR-MEM group, as confirmed by a two-sample t test (*p = 0.007). However, during A/PR/8/34 rechallenge, no intergroup differences in Ab titer were identified.
