What are adrenergic receptors?

Adrenergic receptors are proteins that are sensitized to specific chemical compounds. Some types of cells contain these proteins together with others to allow the cellular signaling in which the cells communicate together using chemical signals. These proteins are most sensitive to norepinephrine and epinephrine, two neurotransmitters connected to the function of the sympathetic nervous system. The famous "combat or flight syndrome" experienced by stress people is mediated by adrenergic receptors. These proteins can stimulate a number of answers that cause muscle contractions, are involved in certain secretions and modulate blood pressure.

There are two main types of adrenergic receptor: alpha and beta. There are also a number of smaller subtypes, each responsible for specific types of responses and sensitized to specific neurotransmitters. Some chemical compounds act as agonists and stimulate adrenergic receptors, while others act as the syntagonists blocking the effectseins. These compounds can be created by the body in response to the situation and can also be randomly or intentionally introduced by the ingestion of certain substances. heart muscle contractions; dilatation and narrowing of blood vessels; Secretion inhibitions such as saliva, insulin and histamines; and support of increased body secretions. When someone's heart begins to pound and blood pressure begins to rise during stress, it is partly due to the action of adrenergic receptors in the body.

scientists studied adrenergic receptors to learn more about what they were doing and where they can be found in the body. This research is used to better understand the functioning of the body, and for the development of drugs that can target specific receptors to achieve the desired effect. For example, vasoconstrictors and vasodilators can be designed with substances that interact with adrenergic receptors that promote narrowing or expansion of blood vessels.

these specialized proteins arealso known as adrenoreceptors. They are one of the large family of proteins found in the cell membrane that are sensitized to specific classes of chemical compounds. Daily these proteins are constantly active, as part of a larger system that keeps the body smoothly running; Communication between millions of cells in the body makes everything from stimulating the digestive system into the contract to push the food along the way to tell the heart when to beat.
