Neurokinin A is a neuropeptide that plays a significant role in the nervous system. It is part of the tachykinin family, which includes other peptides like Substance P and Neurokinin B. Neurokinin A is primarily involved in processes such as pain perception, inflammation, and the regulation of various physiological functions. This peptide acts by binding to specific receptors known as Neurokinin-1 and Neurokinin-2 receptors. These interactions can influence smooth muscle contraction, cardiovascular responses, and even mood regulation. Research into Neurokinin A may provide insights into potential treatments for conditions like asthma and other inflammatory diseases.
