General information

  • The anti-proliferative effect of neurokinin-A on hematopoietic progenitor cells is partly mediated by p53 activating the 5' flanking region of neurokinin-2 receptor. [1]
  • Neurokinin A is the predominant tachykinin in human bronchoalveolar lavage fluid in normal and asthmatic subjects. [2]
  • Neurokinin A is a peptide neurotransmitter of the tachykinin family with potential as a major mediator in human airway and gastrointestinal tissues. [3]
  • Neurokinin A acts via a receptor (the NK-2 receptor) believed to be localized on smooth muscle cells and pharmacologically coupled to a GTP-binding protein. [3]
