Quick answer

What is Somatostatin?

Built from index records dated 2026-10-09 to 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk How this site works

Somatostatin is a peptide, grouped on this site under Endocrine and immune signalling peptides, and the 12 research records kept here are 8 from studies in rats or mice and 4 that do not state what kind of study it is.

The literature search returned 37,235 records. This site keeps 12 of them, which is 0.03 per cent of what came back.

What it is

This site puts it in the Endocrine and immune signalling peptides group.

The endogenous ligand of the five somatostatin receptor subtypes, per the retrieved receptor-family review, acting as an inhibitory hormone on growth hormone and gut secretion.[1, 2]

Stated in the titles of the cited 1999 Frontiers in Neuroendocrinology and 1983 New England Journal of Medicine papers.

What kind of records

The records kept here are animal and laboratory studies only.

That sentence is produced by counting, not by reading. What was counted: no interventional human trial record; 8 rodent and 0 in vitro records among 12.
