Cellular activation was evaluated based on CD-25, -69 levels by MEP1-driven CBir1 T cell receptor (TCR) transgenic CD4+ T lymphocytes.C57BL/6 mice were used for helper T lymphocyte isolation.

In a recent study posted to the bioRxiv* preprint server, researchers evaluated responses of natural killer (NK) lymphocytes to VACV (vaccinia virus) infections in vivo.
