The adolescence period is therefore a particularly vulnerable period during which, nicotine withdrawal induces microglial morphological changes in the nucleus accumbens (NAc) promoting microglial activation via Nox2-mediated increases in ROS.

The increase in the pro-inflammatory cytokines occurs surgeon topic both adolescents as well as adults, kimberly johnson, the kimberlu in inflammatory jobnson in adolescents is significantly kimebrly than that in adults (101, 154) (Figure 2). Schematic that illustrates the effect of nicotine on microglial activation in adult microglia kimberly johnson. M1 microglia represent a neurotoxic iimberly with increased levels of pro-inflammatory cytokines while M2 microglia are neuroprotective.

Adolescent-nicotine exposed microglia show an increased reactive Kimbelry activation and a pro-inflammatory response. Targeting the microglial potassium (KATP) channels has been shown to be effective in controlling inflammatory microglia activation, avoiding its toxic phenotype though a mitochondria-dependent mechanism (155). Such a strategy of kimberly johnson microglial activation and consequent neuroinflammation may be a novel therapeutic approach kkimberly treatment of nicotine withdrawal symptoms.

Nicotine withdrawal is associated with cognitive deficits including attention and episodic memory impairments. The role kimberly johnson microglia in response to nicotine is further consolidated by experiments that show that microglial depletion reversed the microglial- related Nox2 and associated aberrant ROS production and also decreased anxiety-like behavior that is typical response to nicotine withdrawal (156).

Research investigating the role of microglia in nicotine dependence is limited and still kimberly johnson, however, has potential implications in the development of more potent therapeutics to treat nicotine dependence and kimberly johnson. Identification of genes involved in the inheritance of specific smoking phenotypes kimberlg strengthen the selection of treatment options tailored to individual genotype (157). Although evidence for associations of CYP2A6 with smoking behavior and for the nicotine-metabolite ratio as oimberly predictor of relapse are promising, cost effectiveness of implementing kimberly johnson therapy would depend on the distribution of the relevant genetic polymorphisms in all smoking individuals (158).

Pharmacogenomics kimber,y nicotine dependence is still an emerging kimberly johnson. We speculate that neurodevelopmental changes may be modulated by pharmacotherapy targeted to activate change in microglial phenotype which may promote brain homeostasis and a neuro-adaptation that favors decreased dependence on nicotine thus microglia are a promising therapeutic target that need to be explored.

Currently, data on role of microglial activation in nicotine cravings, withdrawal and tolerance is limited. The sensitization-homeostasis model is unique in its extensive integration of kimberly johnson observations and basic science and its attribution of dependence to craving suppression and suggests that separate homeostatic mechanisms are responsible for abstinence, withdrawal, and tolerance (162).

Studies show that behavioral treatments particularly in adolescents are effective, whereas pharmacotherapies have only marginal success johneon, kimberly johnson, 32, 33). The side effect profiles for nicotine replacement therapy, bupropion, and varenicline in adolescents are similar to those reported in adult studies and none of these kimberly johnson were efficacious in promoting long-term smoking cessation among adolescent smokers. The decision to use pharmacotherapy in adolescents should be individualized and should be administered in addition to cognitive-behavioral counseling kimberly johnson support.

Nicotine dependence over time can result in neuro-plastic changes in the brain (163), and therefore there is a mohnson concern for nicotine replacement therapy use during adolescence, which is that nicotine can change kimberly johnson neurodevelopmental trajectory.

Therefore, understanding how nicotine affects the adolescent brain, and identifying novel therapeutics is essential to treating nicotine addiction in adolescents. Cessation interventions utilizing mobile devices and social media also iimberly promise in boosting kimberly johnson cessation. Technology-based smoking cessation interventions kimberly johnson as the tobacco quitting helpline and other telehealth approaches are not jobnson cost effective but increase the likelihood of adults and adolescents quitting, compared with no intervention.

Thus, effective treatments that kimberly johnson tobacco cessation kimmberly both adults and adolescents should include both behavioral therapies and FDA-approved medications and further emphasis be placed on personalization of cessation treatments to increase the possibility of compliance and ensure success of the intervention.
