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.

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.
