概括
电子烟的溶剂乙烯甘醇 (PG) 改变了大脑的基因表达,潜在地提供了对尼古丁和大麻依赖的保护. 然而,PG也可能引起神经炎症,特别是对于使用某些抗逆转录病毒药物的人来说.
科学领域:
- 神经科学是一个神经科学.
- 分子生物学分子生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 电子烟的使用在艾滋病毒感染者 (PWH) 中普遍存在,并被销售为比传统吸烟更安全.
- 早期生长受体2 (EGR2) 和活动调节的细胞骨相关蛋白 (ARC) 与成,神经炎症和神经退行有关.
- 与艾滋病毒相关的神经认知障碍是PWH的一个重大问题.
研究的目的:
- 为了研究电子烟蒸汽成分对大脑基因表达的影响.
- 探索甘醇 (PG) 的潜在神经保护或神经炎症作用及其与尼古丁 (NIC),THC和HIV抗逆转录病毒药物 (DTG) 的相互作用.
主要方法:
- 暴露Sprague Dawley大鼠在电子烟蒸汽中的10天时间.
- 使用培养的C6大鼠星体细胞进行了体外研究.
- 在脑组织和星球细胞中对EGR2和ARCmRNA表达的分析.
- 研究PG,NIC,THC和DTG对基因表达的影响.
主要成果:
- 在大鼠前皮层中,PG降低了EGR2和ARCmRNA的调节,这种效应被NIC和THC逆转.
- 在体外,PG在星球细胞中调节了EGR2和ARCmRNA,这表明神经炎症的潜力.
- NIC逆转了星球细胞中PG诱导的上调,但THC没有.
- 艾滋病毒抗逆转录病毒DTG逆转了NIC对PG诱导的EGR2上调调节的影响.
结论:
- 电子烟溶剂PG可能具有双重作用,可能保护NIC/THC依赖,但也诱导神经炎症.
- 由于EGR2在HIV潜伏期,T细胞亡和神经炎症中的作用,PG,NIC和DTG之间的相互作用对PWH是令人担忧的.
- 需要进一步的研究来了解PWH中电子烟使用的长期神经后果,特别是关于抗逆转录病毒相互作用.

Stimulants
216
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

CNS Depressants: Alcohol and Nicotine
215
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
203
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...
