The ratio of the percentage of IFN-γ producing Ly49H+ NK cells to the percentage of IFN-γ producing Ly49H− NK cells from WT→ WT (n=6), WT → m157-Tg (n=8), DAP12ki→ WT (n=4), DAP12ki → m157-Tg (n=5), DAP10ko→ WT (n=4), DAP10ko → m157-Tg (n=6) mice following stimulation with plate bound anti-NK1.1 mAb (PK136). Donor cells were assessed 24 hours post transfer. The results are presented as the mean ± SEM.
