RGS1 and infection: This prominent Rgs1 mRNA expression level in OT-I cells in the small intestinal IEL and LPL compartment of Lm-OVA infected mice was maintained throughout the entire infection period (up to day 30 p.i.)while the induction of Hobit/Zfp683 was less pronounced, but also gradually increased during the memory phase of infection (day 30 p.i) (Figures 3C, D).
