KLRG1 and infection: We found that the proportion of SLECs, identified as KLRG1+/CD127-, was significantly decreased 40 days after infection and the proportion of MPECs, identified as, KLRG1-/CD127+ was significantly increased 40 days after infection in both blood (Fig 2C) and in spleen (Fig 2D) in 4-month old Dusp5-/- mice compared to age-matched WT mice.
