Invited review Inside-out neuropharmacology of nicotinic drugs

Upregulation of neuronal nicotinic acetylcholine receptor (AChR) is a measurable result of long-term exposure to nicotine; however, it is a pharmacologic association between nicotine and other nicotinic ligands, especially agonists It is one of several results of. The nicotine ligand penetrates the cell membrane and binds to the immature AChR oligomer, resulting in incompletely understood conformational recombination, increased interaction between adjacent AChR subunits, and promotion of maturation of the AChR pentamer Bring. These changes and stabilization will in turn lead to an increase in antegrade and retrograde traffic in the early secretory pathway. In addition to the ultimate upregulation of AChR on the plasma membrane, other effects of pharmacological partners include modifications to endoplasmic reticulum stress and unfolded protein responses. As these processes rely on pharmacological partners within the cellular organelle, we classify them as "pharmacology from the back". This term is in contrast to the better known acute "outward-inward" effect of activating and desensitizing the plasma membrane AChR. I reviewed the existing knowledge about the mechanism and outcome of endogenous pharmacology.

Nicotine addiction and neurodegenerative diseases are destructive problems that require better treatment. This project tried to understand what happened in the brains of people who had been exposed to nicotine for a long time. This project proposes a new, internally independent mechanism of action that can reveal new therapeutic goals for addiction, neurodegenerative diseases and psychiatry.

Tobacco is one of the most addictive substances on the earth, but heroin and cocaine alone do not necessarily have the addictive nicotine itself as thought previously. Nicotine is a major addictive substance in tobacco, but recent studies have shown that when consumed in tobacco it may not be addictive. According to studies published in neuropharmacology, "Tobacco use is the most toxic to all substance abuse, paradoxically, nicotine seems to be a weak potentiator in animal models." Nicotine Can combine with other substances Not only can we make tobacco addictive, not just nicotine?

Smoking is very addictive. Nicotine is a drug mainly involved in smoking smoking of tobacco products including tobacco. The addiction of tobacco and other tobacco products caused by nicotine is similar to that of drugs such as heroin and cocaine (13). Nicotine is naturally contained in tobacco plants. But the tobacco company has deliberately designed tobacco to get enough nicotine to make and maintain addiction. The amount of nicotine entering the body depends on how a person sucks the product and on the nicotine content and product design. Nicotine is absorbed by the blood through the lining of the mouth and lungs and spreads to the brain in a matter of seconds. The more frequent and deeper cigarette smoke increases the amount of nicotine absorbed by the body

Monoamine oxidase, smoking and tobacco intoxication ESR and scientist at the University of Wellington Victoria 1 commented that nicotine could release dopamine (a happy medicine), but nicotine itself has no strong effect. Monoamine oxidase (MAO) is an enzyme that removes dopamine in the brains of humans and animals and is inhibited by substances in tobacco smoke. In rats sensitized with nicotine, MAO inhibitors greatly enhance the addictive effect. Dopamine reward for nicotine will increase due to low MAO activity that may enhance nicotine addiction.
