Positive and negative modulation of Bombyx mori adenylate cyclase by 5-phenyloxazoles: identification of octopamine and tyramine receptor agonists.

abstract：:Lepidopteran larvae show a cellular response to invading foreign substances that are larger than hemocytes, for example, parasitoid eggs or larvae. This response is called hemocyte encapsulation and is often accompanied by phenoloxidase (PO)-catalyzed melanization. In the present study, we artificially transplanted en...
