... relatedness of somatostatin receptors is demonstrated by the fact that the UII receptor is activated by micromolar concentrations of somato- statin derivatives and can be blocked by somatostatin antagonists ... neurons [22]. UII receptor expression seems rather ubiquitous when assessed with highly sensitive RT-PCR technol- ogy. It has to be kept in mind however, that the UII r...
