Fig. 3. Killing of YAC-1 target cells by circulating NK cells (A – all E:T ratios; B – average of 4 highest E:T ratios).
(A, B) Surgery but not PGE2 administration reduced NK cell cytotoxicity in sham operated animals. Both treatments did not affect NK cytotoxicity in adrenalectomized animals. (C) Circulating NK numbers: Adrenalectomy elevated circulating NK cell numbers compared to sham operated animals. * indicates a significant reduction in NK cell cytotoxicity compared to respective control group. # indicates a significant elevation in NK cell numbers in adrenalectomized animals compared to sham operated animals. Data presented as mean + SEM.
