This molecule is used by both alpha- and beta-cells to monitor the amount of glucose in the blood.

Solution

Somatostatin is a molecule used by both alpha and beta-cells to monitor the amount of glucose in the blood. Beta cell peptide Urocortin3 (Ucn3) triggers the release of somatostatin to attenuate further insulin release in negative feedback fashion it also inhibits the release of glucagon. Therefore, used by both alpha and beta cells of pancreas.
