Tyrobp–/– mice received 1 × 105 CD45.1+ WT Ly49H+ NK cells and either 1 × 105 CD45.2+ Themis2–/– or Zfp740–/– Ly49H+ NK cells and then infected with MCMV, as described previously22.

To analyze the secondary expansion of memory NK cells, Tyrobp–/– mice received 1.5 ×106 CD45.1+ WT Ly49H+ NK cells and 1.0 × 106 CD45.2+ Themis2–/– Ly49H+ NK cells and then infected with MCMV. On day 28 pi, donor memory CD45.1+ WT and CD45.2+ Themis2-/- NK cells were enriched from the spleen of the recipient mice as described above. Naïve Tyrobp–/– mice received 3.0 × 105 memory CD45.1+ WT and CD45.2+ Themis2–/– NK cells and then infected with MCMV.
