The percentage of Maxi cells that expressed Tcf1 was lower compared to P14 cells in the LN upon MCMV-ie2-GP33 infection (Fig. 1g and Supplementary Fig. 3a), probably owing to more frequent/abundant expression of the M38316-323 epitope upon viral reactivation than the GP33-41 epitope. The gene discussed is TCF7; the disease is infection.
