Histamine
Histamine — A biogenic amine derived from histidine decarboxylation that mediates inflammatory and allergic responses, often co-released with neuropeptides.
What Is Histamine?
Histamine is a biogenic amine derived from histidine decarboxylation that mediates allergic responses, gastric acid secretion, and neurotransmission through H1-H4 receptors. While not a peptide itself, histamine release is triggered by peptide signals and is a common endpoint in peptide biocompatibility and immunogenicity testing.
Peptide Context
- GHRP-6: Causes histamine release from mast cells (side effect). Ipamorelin does not
- Substance P: Triggers mast cell degranulation and histamine release
- Safety testing: Histamine release assay evaluates peptide mast cell reactivity
