dexamethasone | inhibitor of PLA2, phagocytosis of hemocyte monolayers is significantly reduced in cells provided by insects treated with dexamethasone (0.125 mM), when compared to untreated controls or hemocytes taken from insects treated with dexamethasone but that receive inoculation of arachidonic acid or platelet activating factor. Inhibits total PLA2 activity in lysates from hemocytes by 42%. Cell-free hemolymph PLA2 activity is not affected by dexamethasone treatment (slight but not significant inhibition) | Rhodnius prolixus |
