Moreover, TEM cell subsets in the liver were either associating with a solitary infection with LCMV Armstrong (Li cluster 1; Ly6ChighCD27+CD127+Sca-1+) or MCMV-GP33 (Li cluster 10; KLRG1+CX3CR1+) or were found in both infections but elevated upon co-infection (Li cluster 9; KLRG1+CX3CR1+NKG2A+, Li cluster 12; KLRG1+CX3CR1+NKG2A+CD11c+CD39+). Here, ENTPD1 is linked to coinfection.
