Once the signal has been internalized, mitogen activated protein kinase (MAPK) and/or cAMP-dependent protein kinase (PKA) cascades amplify and integrate various stimuli.

A variety of different candidate molecules, in . and other cnidarians, have been proposed as putative morphogens. They are derived from different cellular sources and the evidence for their ability to ac

The flatworms are the first metazoans to show centralization of the nervous system, with the formation of a “brain”. They possess a variety of potential transmitter substances and this chapter

Hormonal mechanisms along with enzymatic processing similar to those found in vertebrates occur in annelids, for example, the renin-angiotensin system. Furthermore, amino acid sequen
