.... The number and morphology of Inka cells can be very variable even in the same individuals or related insects, but all produce peptide hormones that are completely released at each ecdysis. Injection of tracheal extracts prepared from representatives of several insect orders induces pre-ecdysis and ecdysis...

... either by the application of an Aplysia cardioactive peptide,NdWFamide, or by the stimulation of a nerve innervating the aorta (the vulvar nerve). We found that the enterins activate the 4-aminopyridine(4-AP)-sensitive K + channels, and thereby hyperpolarize the membrane potential of the aortic muscles...

...James D. Baker; Susan L. McNabb; James W. Truman ABSTRACT In insects, ecdysis is thought to be controlled by the interaction between peptide hormones; in particular between ecdysis-triggering hormone (ETH) from the periphery and eclosion hormone (EH) and crustacean cardioactive peptide (CCAP) from...

These Inka cells release the peptide ecdysis-triggering hormone, which helps elicit ecdysial behavior at the molt, and we show that they are also recognized by the myomodulin (MM) antibody. In both D. melanogaster and M. sexta , the PM...
