The purpose of this article is to briefly review our current understanding of endorphins, specifically beta-endorphins, and how they relate to the field of surgery. Beta-endorphins are neuropeptides involved in pain management, possessing morphine like effects, and are involved in natural reward circuits such as feeding, drinking, sex and maternal beta endorphines.

They are also located in high concentrations in the Periaqueductal gray , Locus coeruleus , and the Rostral ventromedial medulla. Voltage-dependent calcium channels VDCCs are important membrane proteins that mediate the depolarization of neurons, and play a major role in promoting the release of neurotransmitters. When the sub-unit binds to the voltage-dependent calcium channel, it produces a voltage-dependent block, which inhibits the channel, preventing the flow of calcium ions into the neuron. Embedded in the cell membrane is also the G protein-coupled inwardly-rectifying potassium channel. This is when there is a change in the membrane's potential, so that it becomes more negative. The reduction in calcium ions causes a reduction of neurotransmitter release because calcium is essential for this event to occur.

In the brain, the peptide and other related proteins are most prevalent in the hypothalamus, thalamus—midbrain, amygdala, hippocampus, and brainstem [ 1 ]. The peptide is typically released to the periphery in response to a painful or stressful event, where they inhibit somatosensory fibers, with a focus on nociceptors [ 2 ]. It should also be noted that endomorphins are peptides which have been isolated in brain and immune tissue that exhibit the highest affinity for the mu opioid receptor [ 29 , 30 , 31 , 32 ], but as no precursor has yet been identified, it is unclear if they are truly endogenous [ 33 ]. The effects of the HPA can be tied to a variety of behaviors, including exercise, drug-use, sexual behaviors, among others [ 38 ]. Kowalski et al. Contrary to other body regions, Sacerdote et al. Studies involving human subjects are much less consistent than their animal counterparts.

They are naturally produced during pleasurable activities like exercise, sex, and laughing, as well as painful experiences, such as twisting your ankle. This article dives deep into endorphins, including why we need them and tips on how to naturally increase their levels. Endorphins, also known as endogenous opioids, are groups of protein chains called peptides. While various forms of endorphins exist, beta-endorphins are the most studied and known for their pain-relieving effects 1 , 2. For example, endorphins are released during painful experiences, such as when you sprain your ankle, to temporarily relieve pain and discomfort.

Beta-endorphins are neuropeptides involved in pain management, possessing morphine like effects, and are involved in natural reward circuits such as feeding, drinking, sex and maternal behavior. Beta-endorphins are primarily synthesized and stored in the anterior pituitary gland 2 from their precursor protein proopiomelanocortin POMC. However, recent studies suggest cells of the immune system are also capable of beta-endorphin synthesis because immune cells possess mRNA transcripts for POMC 3 and T-lymphocytes, B-lymphocytes, monocytes and macrophages have been shown to contain endorphins during inflammation. The pituitary gland synthesizes POMC in response to a signal from the hypothalamus; that signal being corticotroponin-releasing hormone CRH.

The degree of pain experienced by the surgical patient during and after a procedure correlates with plasma beta-endorphin level. In the CNS, mu-opioid receptors are most abundant in descending pain control circuits including the amygdala, mesencephalic reticular formation, periaqueductal gray matter PAG and rostral ventral medulla.
