Overall, the lack of any significant differences in islet size, hormone content, or morphology between Sst -/- and control islets suggested that the observed differences in hormone secretion are most likely due to the absence of SST. (medscape.com)
Consequently, our in vitro studies demonstrated that the lack of locally released δ-cell SST had a profound effect on both insulin and glucagon secretion, leading to enhanced levels of stimulus-induced release of both hormones from Sst -/- islets compared with control islets without affecting basal levels of hormone secretion. (medscape.com)
Under resting conditions, the quiescent δ-cells exert little or no influence on the neighboring α- and β-cells, and no difference is observed between control and Sst -/- islets with regard to basal secretion nor in the basal levels of plasma insulin and glucagon between control and Sst -/- mice. (medscape.com)
However, exposure of islets to glucose or sulfonylureas activates both β-cells and δ-cells, [ 1 , 34 ] which initiates an insulin secretory response and simultaneously causes the local release of SST to limit that response. (medscape.com)
The proposed model of paracrine regulation of islet function by δ-cell SST is further supported by our observations that exogenous SST had no significant effect in vitro on stimulus-dependent insulin or glucagon secretion from control islets but exerted a marked inhibition of secretion of both hormones from Sst -/- islets.

these oscillations trigger glucagon secretion. (nih.gov)
