Opioid peptide
(Redirected from Endogenous opioid)
Opioid peptides are small molecules that are used by neurons to communicate with each other. They are found in the brain, spinal cord, and other parts of the body. Opioid peptides can produce a wide range of effects, including feelings of pain relief, pleasure, and relaxation.
Structure and Function[edit | edit source]
Opioid peptides are composed of short sequences of amino acids, the building blocks of proteins. They are called "opioid" because they are able to bind to opioid receptors in the brain and other parts of the body, much like opiate drugs such as morphine and heroin.
There are several different types of opioid peptides, including endorphins, enkephalins, and dynorphins. These peptides are produced by the body and are involved in a wide range of physiological functions, including pain regulation, mood control, immune response, and stress response.
Role in Pain Regulation[edit | edit source]
One of the most important roles of opioid peptides is in the regulation of pain. When the body experiences pain, it releases opioid peptides that bind to opioid receptors in the brain and spinal cord. This binding action inhibits the transmission of pain signals, leading to a reduction in the perception of pain.
Role in Mood Control[edit | edit source]
Opioid peptides also play a key role in mood control. They are involved in the regulation of emotions and feelings of pleasure and reward. For example, the release of endorphins, a type of opioid peptide, is associated with feelings of happiness and euphoria.
Role in Immune Response[edit | edit source]
In addition to their roles in pain regulation and mood control, opioid peptides are also involved in the body's immune response. They have been shown to modulate the activity of immune cells, influencing the body's response to infection and disease.
Role in Stress Response[edit | edit source]
Opioid peptides are also involved in the body's response to stress. They are released in response to stressful stimuli and can help to reduce the physiological and psychological effects of stress.
