What is Substance P (1-7), and how does it differ from regular Substance P?

Substance P (1-7) is a specific fragment of the well-known neuropeptide Substance P, which is an important player in a variety of physiological processes including pain modulation and the inflammatory response. Substance P is a member of the tachykinin peptide family, broadly recognized for its role as a neurotransmitter and neuromodulator. The full-length molecule is an 11-amino-acid peptide, whereas Substance P (1-7) is a truncated version consisting of only the first seven amino acids. This structural difference is significant as it imparts distinct biological activities and interactions compared to the full-length peptide.

The primary role of substance P is associated with the transmission of pain signals from peripheral nerve endings to the central nervous system. It is heavily implicated in the neurogenic inflammation process, contributing to the pathophysiology of pain and inflammatory diseases. However, the (1-7) fragment exhibits unique properties that differentiate it from the full-length peptide. Research indicates that Substance P (1-7) can bind to atypical receptors and may actually exert antinociceptive (pain-reducing) effects, contrary to the full-length peptide's pronociceptive (pain-inducing) role. This distinct activity profile makes the peptide fragment a subject of interest in pain management research.

In addition to analgesic potential, Substance P (1-7) may modulate immune responses differently compared to its predecessor. The immunomodulatory effects of the full-length peptide, including its role in promoting inflammation and hyperalgesia, are well-documented. In contrast, (1-7) can influence cytokine production and immune cell activity in a way that may counteract some of these inflammatory processes. Understanding these opposing biological effects is facilitated by studying the specific interactions that Substance P (1-7) engages within cellular environments.

Furthermore, Substance P (1-7) is being explored for its potential in neurodegenerative disorders.
