At their core, opioid peptides are peptides, which are short chains of amino acids. They are classified as opiacés, meaning they are compatible with and can bind to opioid receptors. Unlike exogenous opioids such as morphine, opioid peptides are endogenously produced by the body, acting as key signaling molecules within the nervous system and beyond. The discovery of these internal opioid systems, most notably endorphins, otherwise known as the endogenous opioid peptides, revolutionized our understanding of pain perception and reward pathways. However, the family of endogenous opioid peptides is broader, encompassing prominent classes such as the ENKEPHALINS, the DYNORPHINS, and the ENDORPHINS. These are derived from precursor genes like pre-proenkephalin A or pro-opiomelanocortin (POMC).

This interaction can then influence calcium channel activity, with studies exploring modulation de conductances calciques par les peptides opioïdes et antiopioïdes. In situations of physiological stress or aggression, the secretion of peptides opioides endogènes (POE) is stimulated, suggesting a protective role. These peptides are not only found in the nervous system but also in other tissues, indicating their widespread influence.

The field of opioid peptide research is continuously expanding, revealing novel sources and functionalities. Food-Derived Opioid Peptides in Human Health is a growing area of interest, with certain protein fragments from food, such as those derived from gluten and β-caseins, being identified as potentially bioactive. The UriPep® analysis, for instance, focuses on detecting the presence of peptides opioïdes originating from gluten and dairy.2021年3月5日—Les peptides opioïdes endogènessont sécrétés en réponse à certains stimulus, en particulier les signaux provenant des nerfs sensitifs, puis ... Similarly, bioactive peptides in milk and dairy products are recognized for their positive impact on various bodily functions.

Given their potent effects and natural presence, opioid peptides present promising avenues for therapeutic development. The search for alternatives to traditional opioid medications, particularly for chronic pain management, has led to an exploration of peptide-based therapies. A key advantage of some advanced peptide designs is their ability to disrupt endocytosis when applied locally at pain nerve endings, offering a targeted approach to pain relief. These synthetic δ-opioid peptide agonists, while having some activity at μ-opioid receptors, demonstrate neuro- and tissue-protective properties and can modulate gene expression. The development of endomorphin molecules, which represent some of the first peptides isolated from brain shown to bind the µ-opioid receptor with high affinity and selectivity, further underscores the potential of endogenous peptide systems for therapeutic targeting.
