What Are Nicotine Receptors?
Some people ca nt do without cigarettes for almost a moment, all of which are the nicotine receptors in the human brain. The nicotine in the main component of tobacco is inhaled and binds to specific receptors in the human brain, which promotes happiness in the brain. The central release of dopamine produces a "reward effect".
Nicotine receptor
- Chinese name
- Nicotine receptor

- Nicotine receptors in the human brain
- Brief introduction
- Promote the release of dopamine from the happy center in the brain
- Some people ca nt do without cigarettes for almost a moment, all of which are the nicotine receptors in the human brain. The nicotine in the main component of tobacco is inhaled and binds to specific receptors in the human brain, which promotes happiness in the brain. The central release of dopamine produces a "reward effect".
- Scientific research shows that the main ingredients in tobacco
- Taipei Medical University research team announced a new medical discovery in July 2010 that there is a nicotine receptor on the surface of breast epithelial cells, which is stimulated by nicotine in cigarettes, which can lead to canceration of cells. Therefore, smoking or second-hand smoke can cause breast cancer.
- According to "Central News Agency", He Yuanshun, professor of the Department of Medical Laboratory and Biotechnology, Taipei Medical University, said that he and the research members found that the nicotine receptor 9 on the surface of breast epithelial cells, under the continuous stimulation of nicotine, the cells overreact and will automatically activate and reactivate The development of more receptors, 9, over time, has caused cell canceration and tumor proliferation. The research team further found that when cells with overreacted receptor 9 were implanted in immunodeficient mice, cancer cells grew rapidly as if they stepped on the throttle; on the contrary, using gene regulation technology to inhibit 9 activity, tumors would shrink significantly. .
- He Yuanshun said that 9 is very sensitive to nicotine. When it encounters a dose of 7M (M is equal to 1 billionth of a mole), the combination of 9 and nicotine will reach saturation within 60 minutes. The concentration of second-hand smoke was about 200M, and it was found that the concentration of 7M was extremely low. Wu Zhixiong, a professor of North Medical Surgery, said that the research team also analyzed the breast cancer tissues of 276 female patients on the island and confirmed that 9 was related to smoking addiction. The expression of 9 in females with smoking addiction was two to three times that of second-hand smokers and non-smokers. And the more active 9 is, the more malignant breast cancer is, and when it is found, it is usually the advanced or end stage of breast cancer.
- The evidence that smoking will lead to breast cancer in the past mainly comes from epidemiological and indirect molecular biological research. This research is to find direct evidence, which will find important biomolecular targets for the future development of breast cancer anticancer drugs. [2]
