The frequency of KLRG1hiCD127lo SLECs in both the OT-I and bulk CD44+ populations 10 days after antigen stimulation verify that this model effectively recapitulates previously observed differences with a significant presence of SLECs following MHV68-OVA infection and virtually none following mOVA skin transplantation (Supplemental Figure 7B). The gene discussed is CD44; the disease is infection.
