Abstract
Coelomocytes of the earthworm Lumbricus terretris caused significant s pontaneous allogeneic cytotoxicity in a 24-h trypan blue assay, but no t in an assay using lactate dehydrogenase (LDH) release. Allogeneic cy totoxicity assays using cells from worms exposed to polychlorinated bi phenyls (PCBs) suggest that PCBs can suppress a natural killing (NK-li ke) reaction. The implications of this work are twofold: understanding the evolution of natural killing (NK-like) activity and providing pre liminary information on how spontaneous killing, a component of cellul ar immunity, may be compromised by pollutants.
