Roaches: granted - transplant - immunity?

Roaches: Granted (transplant) immunity?

Hardly sauve and debonair, the cockroach is a primitive kindof guy that nonetheless has survived more than 350 million years. But the pest may be more sophisticated than it's given credit for, according to University of Cincinnati scientist Richard D. Karp. That sophistication doesn't come from the cockroach's black tie and tails, but from its surprisingly advanced immune system.

In a report in the April TRANSPLANTATION, Karp says theinsect's immune arsenal includes allograft immunity, the process responsible for rejecting transplants from donors of the same species. Previous work at the Cincinnati lab had shown that cockroaches produce antibody-like substances against venom of other insects. The ability to reject grafts, long observed in higher animals, is evidence that the insect also has cell-mediated immunity.
