CD8A and infection: To further explore the role of LFA-1 in CD8 TEFF function during an LCMV-CL13 infection, we compared the anti-viral response kinetics of adoptively transferred CD8+ TN from LFA1+/+ and LFA-1−/- donors that had been crossed to P14 mice, which express atransgenic TCR that recognizes an immunodominant epitope of LCMV, gp33-41, in H-2 Db [27].
