Neurokinin B is a naturally occurring neuropeptide belonging to the tachykinin family, primarily involved in modulating pain signaling, inflammatory responses, and cardiovascular regulation through activation of neurokinin-3 (NK-3) receptors. Structurally distinct from Substance P and Neurokinin A, it exhibits specificity for NK-3 receptors, mediating effects such as vasodilation, smooth muscle contraction, and immune modulation. In pharmacological research, Neurokinin B serves as a tool to investigate NK-3 receptor activation mechanisms, structure-activity relationships, and potential therapeutic applications for pain management, inflammatory disorders, and cardiovascular diseases. Its role in central and peripheral nervous systems underscores its significance in understanding peptide-mediated physiological processes.
