Amino Acid Sequence

His-Lys-Thr-Asp-Ser-Phe-Val-Gly-Leu-Met-NH2

General description

Neurokinin A is an 11 amino acid peptide. It is a member of tachykinin family, which includes neurokinin A, neurokinin B, neuropeptide K, neuropeptide Y and hemokinin-1. The gene encoding neurokinin A is localized on human chromosome 7q21.3.

Biochem/physiol Actions

Neurokinin A improves the multiplication and paracrine ability of stem cells acquired from adipose in vitro. It participates in the movement of several organ tracts, triggers glandular secretion and controls autonomic reflexes. Neurokinin A plays an important role in neuroimmune and systemic autoimmune/inflammatory conditions like multiple sclerosis (MS), rheumatoid arthritis, inflammatory bowel disease and also in infections and cancer.

Recent European investigations have shown that persistently elevated (>50 pg/mL) plasma neurokinin A levels are associated with poor short-term survival in patients with midgut neuroendocrine neoplasms. We hypothesized that American patients with persistently elevated plasma neurokinin A levels (>50 pg/mL)
