[PMID: 36916431 DOI: 10.1016/j.biopha.2022.114205] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/19/2022] [Accepted: 12/30/2022] [Indexed: 01/06/2023] Open
Abstract
Different studies have confirmed that P2X purinergic receptors play a key role in inflammation. Activation of P2X purinergic receptors can release inflammatory cytokines and participate in the progression of inflammatory diseases. In an inflammatory microenvironment, cells can release a large amount of ATP to activate P2X receptors, open non-selective cation channels, activate multiple intracellular signaling, release multiple inflammatory cytokines, amplify inflammatory response. While P2X4 and P2X7 receptors play an important role in the process of inflammation. P2X4 receptor can mediate the activation of microglia involved in neuroinflammation, and P2X7 receptor can mediate different inflammatory cells to mediate the progression of tissue-wide inflammation. At present, the role of P2X receptors in inflammatory response has been widely recognized and affirmed. Therefore, in this paper, we discussed the role of P2X receptors-mediated inflammation. Moreover, we also described the effects of some antagonists (such as A-438079, 5-BDBD, A-804598, A-839977, and A-740003) on inflammation relief by antagonizing the activities of P2X receptors.

Abstract
The use of psychostimulant drugs can modify brain function by inducing changes in the reward system, mainly due to alterations in dopaminergic and glutamatergic transmissions in the mesocorticolimbic pathway. However, the etiopathogenesis of addiction is a much more complex process. Previous data have suggested that microglia and other immune cells are involved in events associated with neuroplasticity and memory, which are phenomena that also occur in addiction. Nevertheless, how dependent is the development of addiction on the activity of these cells? Although the mechanisms are not known, some pathways may be involved. Recent data have shown psychoactive substances may act directly on immune cells, alter their functions and induce various inflammatory mediators that modulate synaptic activity. These could, in turn, be involved in the pathological alterations that occur in substance use disorder. Here, we extensively review the studies demonstrating how cocaine and amphetamines modulate microglial number, morphology, and function. We also describe the effect of these substances in the production of inflammatory mediators and a possible involvement of some molecular signaling pathways, such as the toll-like receptor 4. Although the literature in this field is scarce, this review compiles the knowledge on the neuroimmune axis that is involved in the pathogenesis of addiction, and suggests some pharmacological targets for the development of pharmacotherapy.

Fan L, Chen H, Liu Y, Hou H, Hu Q. ERK signaling is required for nicotine-induced conditional place preference by regulating neuroplasticity genes expression in male mice. Pharmacol Biochem Behav 2023; 222:173510. [PMID: 36565790 DOI: 10.1016/j.pbb.2022.173510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/24/2022]
Abstract
Nicotine is an addictive compound that interacts with nicotinic acetylcholine receptors (nAChRs) in the ventral tegmental area (VTA), inducing a release of dopamine in the nucleus accumbens (NAc). When neurons undergo repeated exposure to nicotine, several adaptive changes in neuroplasticity occur. Activation of nAChRs involves numerous intracellular signaling cascades that likely contribute to neuroplasticity and ultimately the establishment of nicotine addiction. Nevertheless, the molecular mechanisms underlying this adaptation remain unclear. To explore the effects of nicotine on neuroplasticity, a stable nicotine-induced conditioned place preference (CPP) model was constructed by intravenous injection in mice. Using a PCR array, we observed significant changes in the expression of synaptic plasticity-related genes in the VTA (16 mRNAs) and NAc (40 mRNAs). When mice were pre-treated with PD98059, an extracellular signal-regulated kinase (ERK) inhibitor, more gene expression changes in the VTA (53 mRNAs) and NAc (60 mRNAs) were found. Moreover, PD98059 pre-treatment blocked the increased p-ERK/ERK and p-CREB/CREB ratios and decreased the expression of synaptic plasticity-related proteins such as SAP102, PSD95, synaptophysin, and BDNF, these changes might contribute to preventing the establishment of nicotine-induced CPP. Furthermore, neurons from the VTA and NAc of nicotine CPP mice had an increased dendritic spine density and complexity of dendritic morphology by Golgi staining. PD98059 also blocked this dynamic. These results demonstrate that repeated exposure to nicotine may remold the expression of neuroplasticity-related genes by activating the ERK signaling pathway in the VTA and NAc, and is related to the establishment of nicotine-induced CPP.

Maternal Nicotine Exposure Alters Hippocampal Microglia Polarization and Promotes Anti-inflammatory Signaling in Juvenile Offspring in Mice. Front Pharmacol 2021; 12:661304. [PMID: 34045967 PMCID: PMC8144443 DOI: 10.3389/fphar.2021.661304] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Accepted: 04/26/2021] [Indexed: 12/15/2022] Open
Abstract
Accumulating evidence reveal that maternal smoking or perinatal nicotine replacement therapy impairs hippocampal neurogenesis, neural development, and cognitive behaviors in the offspring. Microglia is a source of non-neural regulation of neuronal development and postnatal neurogenesis. In this study, we explored the impact of nicotine on the microglia during the development of hippocampus. Developmental nicotine exposure in a mouse model was conducted by supplementing nicotine in the drinking water to mother mice during gestation and lactation period. We found that juvenile offspring with maternal nicotine exposure presented physical and neurobehavioral development delay and an increase in anxiety-like behavior in the open field test on postnatal day (PND) 20. To further detect possible developmental neurotoxic effects of nicotine in offspring and underlying mechanism, whole genome microarray analysis of the expression profile of the hippocampus was performed on postnatal day 20. Significant alterations in the expression of genes related to inflammatory, neurotransmitter, and synapsis were observed in the hippocampus after maternal nicotine exposure, as compared to the vehicle control. Concurrently, an increase in microglial markers and the presence of M2 polarity state in the hippocampus of the nicotine offspring were observed by histological analysis and confocal z-stacking scanning. The M2 microglial polarization state was further confirmed with in vitro primary microglia culture by cytokine array, and double-positive expression of BDNF/Iba1 in microglia by immunohistochemical staining in the juvenile offspring hippocampus was visualized. We also found that nicotine offspring showed an increase of neurite length in the molecular layer and CA1 by Tuj1 staining, as well as an increase in the expression of synapse associated protein, PSD95, but the expression of NeuroD1 in CA1 and CA3 reduced. In summary, maternal nicotine exposure dysregulates immune-related genes expression by skewing the polarity of M2 microglia in the hippocampus, which may cause abnormal cognitive and behavioral performance in the offspring.
