| 4 | Presenilin 2 deficiency facilitates Aβ-induced neuroinflammation and injury by upregulating P2X7 expression显示文摘Accumulating evidence suggests that β-amyloid (Aβ)-induced neuroinflammation plays a prominent and early role in Alzheimer’s disease (AD). In this study, we demonstrated that Presenilin 2 (PS2) deficiency facilitates Aβ-induced neuroinflammation and injury by upregulating P2X7 expression both in vitro and in vivo. PS2 knockout mice demonstrated increased cognitive impairments and cerebral injury. PS2 deficiency increased the expression of P2X7 both in neurons and microglial cells.Furthermore, extracellular ATP also increased in both Aβ-treated and untreated PS2 knockout microglial cells. Notably, Aβ-induced classical proinflammatory cytokines such as IL-1β, IL-1α and TNF-α were increased in PS2 knockout microglial cells, suggesting a potential role for PS2 in the regulation of neuroinflammation. The expression of P2X7 clearly increased in PS2 knockdown BV2 cells. Consistent with in vivo data, Aβ-induced IL-1β production was also clearly enhanced in PS2 knockdown BV2 cells. Additionally, expression of the transcription factor Sp1 was increased in PS2 knockdown cells. When we treated PS2 knockdown cells with the specific Sp1 inhibitor MIT, we observed that enhanced P2X7 expression was significantly rescued. Taken together, these data suggests that PS2 plays a protective role during Aβ-induced neuroinflammation and injury through down-regulation of P2X7 expression. | Juliang Qin Xiaoyu Zhang Ziqiang Wang Jinju Li Zhen Zhang Liangcai Gao Hua Ren Min Qian Bing Du | 2017 | Science China(Life Sciences)2017，60，2： | 7 |
| 5 | P2X7/NALP3在急性肾小管坏死肾组织中的表达及意义显示文摘目的观察急性肾小管坏死(acute tubular necrosis,ATN)患者肾组织中P2X7/NALP3的表达情况,探讨其与肾小管损伤程度、肾小管间质炎症、肾小管上皮细胞凋亡情况及肾功能损害之间的关系。方法选取2011-2013年在我科住院治疗,经肾活检诊断为ATN的患者肾组织;以同期外科肾肿瘤切除时远离肾肿瘤的边缘正常肾,且经光镜证实为正常的肾组织为对照。免疫组化法检测ATN患者肾小管上皮细胞中P2X7/NALP3、caspase-1、caspase-3、IL-1β、IL-18的表达,以及肾小管上皮细胞的凋亡;半定量分析肾小管损伤程度及肾小管间质炎症细胞的浸润。收集患者入院第1天24 h的尿量、血肌酐(serum creatinine,Scr)及尿素氮(blood urea nitrogen,BUN)等数据,计算肾小球率过滤(estimated glomerular filtration rate,eGFR),将P2X7/NALP3的表达与肾小管损伤程度、肾间质炎症反应、肾小管上皮细胞凋亡及ATN患者肾功能指标进行相关性分析。结果与对照组比较,ATN患者肾小管上皮细胞P2X7/NALP3表达明显升高(P<0.01),其与caspase-1、caspase-3、IL-1β、IL-18表达水平显著正相关,P2X7/NALP3与ATN患者肾小管损伤(r=0.787,r=0.530)、小管间质炎症细胞浸润程度(r=0.543,r=0.419)、肾小管上皮细胞凋亡程度(r=0.719,r=0.671)、血肌酐(r=0.707,r=0.706)、尿素氮(r=0.584,r=0.623)呈正相关(P<0.01),与肌酐清除率(r=-0.622,r=-0.59)、尿量(r=-0.659,r=-0.62)呈负相关(P<0.01)。结论 ATN患者肾组织中P2X7和NALP3的表达与肾小管上皮细胞凋亡、炎症反应及肾功能损害具有明显相关性,提示P2X7/NALP3可能参与ATN患者肾小管上皮细胞凋亡、炎症反应,进而导致肾小管损伤及肾功能受损。 | 曹雪娇 侯卫平 张媛媛 袁发焕 | 2014 | 第三军医大学学报2014，36，6： | 7 |

| 8 | Neural stem cell transplantation inhibits glial cell proliferation and P2X receptor-mediated neuropathic pain in spinal cord injury rats显示文摘P2X4 and P2X7 receptors play an important role in neuropathic pain after spinal cord injury. Regulation of P2X4 and P2X7 receptors can obviously reduce pain hypersensitivity after injury. To investigate the role of neural stem cell transplantation on P2X receptor-mediated neuropathic pain and explore related mechanisms, a rat model of spinal cord injury was prepared using the free-falling heavy body method with spinal cord segment 10 as the center. Neural stem cells were injected into the injured spinal cord segment using a micro-syringe. Expression levels of P2X4 and P2X7 receptors, neurofilament protein, and glial fibrillary acidic protein were determined by immunohistochemistry and western blot assay. In addition, sensory function was quantitatively assessed by current perception threshold. The Basso-Beattie-Bresnahan locomotor rating scale was used to assess neuropathological pain. The results showed that 4 weeks after neural stem cell transplantation, expression of neurofilament protein in the injured segment was markedly increased, while expression of glial fibrillary acidic protein and P2X4 and P2X7 receptors was decreased. At this time point, motor and sensory functions of rats were obviously improved, and neuropathic pain was alleviated. These findings demonstrated that neural stem cell transplantation reduced overexpression of P2X4 and P2X7 receptors, activated locomotor and sensory function reconstruction, and played an important role in neuropathic pain regulation after spinal cord injury. Therefore, neural stem cell transplantation is one potential option for relieving neuropathic pain mediated by P2X receptors. | Xiao-Jing Du Yue-Xia Chen Zun-Cheng Zheng Nan Wang Xiao-Yu Wang Fan-E Kong | 2019 | Neural Regeneration Research2019，14，5： | 6 |
| 9 | Hydrogen sulfide intervention in focal cerebral ischemia/reperfusion injury in rats显示文摘The present study aimed to explore the mechanism underlying the protective effects of hydrogen sulfide against neuronal damage caused by cerebral ischemia/reperfusion. We established the middle cerebral artery occlusion model in rats via the suture method. Ten minutes after middle cerebral artery occlusion, the animals were intraperitoneally injected with hydrogen sulfide donor compound sodium hydrosulfide. Immunofluorescence revealed that the immunoreactivity of P2X7 in the cerebral cortex and hippocampal CA1 region in rats with cerebral ischemia/reperfusion injury decreased with hydrogen sulfide treatment. Furthermore, treatment of these rats with hydrogen sulfide significantly lowered mortality, the Longa neurological deficit scores, and infarct volume. These results indicate that hydrogen sulfide may be protective in rats with local cerebral ischemia/reperfusion injury by down-regulating the expression of P2X7 receptors. | Xin-juan Li Chao-kun Li Lin-yu Wei Na Lu Guo-hong Wang Hong-gang Zhao Dong-liang Li | 2015 | Neural Regeneration Research2015，10，6： | 6 |
| 10 | 高糖对体外培养的Cajal间质细胞P2X7嘌呤能受体表达的影响显示文摘目的:观察P2X7嘌呤能受体在体外培养的Cajal间质细胞(ICC)的表达及高糖的影响,探讨P2X7嘌呤能受体在糖尿病胃肠功能紊乱的细胞机制.方法:以小鼠小肠组织为来源,联合使用机械分离法和酶解法分离ICC,培养在50mL/LCO2温箱里.同时应用ICC特异的c-Kit抗体和P2X7受体抗体进行免疫荧光染色,在激光共聚焦显微镜下进行鉴定,以确定P2X7受体是否表达于ICC.实验分组:正常对照组(葡萄糖浓度为5.5mmol/L),高糖组(葡萄糖浓度为33mmol/L).通过倒置显微镜观察细胞形态,RT-PCR对P2X7和c-Kit受体的表达进行比较.结果:激光共聚焦显微镜下P2X7受体在c-Kit抗体阳性的细胞上的免疫荧光染色是阳性的;与正常组比较,加入葡萄糖后的ICC细胞变大,突起变短,与周围细胞的网络连接减少;RT-PCR结果显示P2X7受体表达于ICC,加入高糖后的ICC的c-Kit受体表达减弱,而P2X7受体的表达是增强的.结论:P2X7受体表达于体外培养的ICC上,高糖使ICC的形态发生了改变、减弱了c-Kit的表达、加强了P2X7受体的表达.这可能在糖尿病胃肠功能紊乱的发生中发挥一定的作用. | 高显奎 余跃 杨琰 陈军 王巧民 | 2010 | 世界华人消化杂志2010，18，12： | 6 |
| 11 | P2X receptors: New players in cancer pain显示文摘Pain is unfortunately a quite common symptom for cancer patients. Normally pain starts as an episodic experience at early cancer phases to become chronic in later stages. In order to improve the quality of life of oncological patients, anti-cancer treatments are often accompanied by analgesic therapies. The P2 X receptor are adenosine triphosphate(ATP) gated ion channels expressed by several cells including neurons, cancer and immune cells. Purinergic signaling through P2 X receptors recently emerged as possible common pathway for cancer onset/growth and pain sensitivity. Indeed, tumor microenvironment is rich in extracellular ATP, which has a role in both tumor development and pain sensation. The study of the different mechanisms by which P2 X receptors favor cancer progression and relative pain, represents an interesting challenge to design integrated therapeutic strategies for oncological patients. This review summarizes recent findings linking P2 X receptors and ATP to cancer growth, progression and related pain. Special attention has been paid to the role of P2X2, P2X3, P2X4 and P2X7 in the genesisof cancer pain and to the function of P2X7 in tumor growth and metastasis. Therapeutic implications of the administration of different P2 X receptor blockers to alleviate cancer-associated pain sensations contemporarily reducing tumor progression are also discussed. | Alessia Franceschini Elena Adinolfi | 2014 | World Journal of Biological Chemistry2014，5，4： | 5 |

| 13 | P2X_7 receptors in cerebral ischemia显示文摘Cerebral ischemia is one of the most common diseases resulting in death and disability in aged people. It leads immediately to rapid energy failure, ATP depletion, and ionic imbalance, which increase extracellular ATP levels and accordingly activate P2X7 receptors. These receptors are ATP-gated cation channels and widely distributed in nerve cells, especially in the immunocompetent cells of the brain. Currently, interest in the roles of P2X7 receptors in ischemic brain injury is growing. In this review, we discuss recent research progress on the actions of P2X7 receptors, their possible mechanisms in cerebral ischemia, and the potential therapeutic value of P2X7 receptor antagonists which may provide a new target both for clinical and for research purposes. | Hui-Yu Bai Ai-Ping Li | 2013 | Neuroscience Bulletin2013，29，3： | 4 |
| 14 | Role of P2X_7 receptors in the development of diabetic retinopathy显示文摘The P2X7 receptor is one of the members of the family of purinoceptors which are ligand-gated membrane ion channels activated by extracellular adenosine 5'-triphosphate. A unique feature of the P2X7 receptor is that its activation can result in the formation of large plasma membrane pores that allow not only the flux of ions but also of hydrophilic molecules of up to 900 Da. Recent studies indicate that P2X7-mediated signaling can trigger apoptotic cell death after ischemia and during the course of certain neurodegenerative disorders. Expression of the P2X7 receptor has been demonstrated in most types of cells in the retina. This purinoceptor mediates the contraction of pericytes and regulates the spatial and temporal dynamics of the vasomotor response through cell-to-cell electrotonic transmission within the microvascular networks. Of potential clinical significance, investigators have found that diabetes markedly boosts the vulnerability of retinal microvessels to the lethal effect of P2X7 receptor activation. This purinergic vasotoxicity may result in reduced retinal blood flow and disrupted vascular function in the diabetic retina. With recent reports indicating an association between P2X7 receptor activation and inflammatory cytokine expression in the retina, this receptor may also exacerbate the development of diabetic retinopathy by a mechanism involving inflammation. | Tetsuya Sugiyama | 2014 | World Journal of Diabetes2014，5，2： | 4 |

| 16 | Up-regulation of P2X7 Receptors Contributes to Spinal Microglial Activation and the Development of Pain Induced by BmK-I显示文摘Previous work has demonstrated that the sensitization of spinal neurons and microglia is important in the development of pain behaviors induced by BmK I,a Na^+ channel activator and a major peptide component of the venom of the scorpion Buthus martensi Karsch(BmK).We found that the expression of P2X7 receptors(P2X7Rs)was up-regulated in the ipsilateral spinal dorsal horn after BmK I injection in rats.P2X7R was selectively localized in microglia but not astrocytes or neurons.Similarly,interleukin 1β(IL-1β)was selectively up-regulated in microglia in the spinal dorsal horn after BmK I injection.Intrathecal injection of P2X7R antagonists largely reduced BmK I-induced spontaneous and evoked pain behaviors,and the up-regulation of P2X7R and IL-1β in the spinal cord.These data suggested that the up-regulation of P2X7Rs mediates microglial activation in the spinal dorsal horn,and therefore contributes to the development of BmK I-induced pain. | Jingjing Zhou Xiaoxue Zhang You Zhou Bin Wu Zhi-Yong Tan | 2019 | Neuroscience Bulletin2019，35，4： | 4 |
| 17 | Characterization of the Expression of the ATP-Gated P2X7 Receptor Following Status Epilepticus and during Epilepsy Using a P2X7-EGFP Reporter Mouse显示文摘Mounting evidence suggests that the ATP-gated P2X7 receptor contributes to increased hyperexcitability in the brain.While increased expression of P2X7 in the hippocampus and cortex following status epilepticus and during epilepsy has been repeatedly demonstrated,the cell type-specific expression of P2X7 and its expression in extra-hippocampal brain structures remains incompletely explored.In this study,P2X7 expression was visualized by using a transgenic mouse model overexpressing P2X7 fused to the fluorescent protein EGFP.The results showed increased P2X7-EGFP expression after status epilepticus induced by intra-amygdala kainic acid and during epilepsy in different brain regions including the hippocampus,cortex,striatum,thalamus and cerebellum,and this was most evident in microglia and oligodendrocytes.Colocalization of P2X7-EGFP with cell type-specific markers was not detected in neurons or astrocytes.These data suggest that P2X7 activation is a common pathological hallmark across different brain structures,possibly contributing to brain inflammation and neurodegeneration following acute seizures and during epilepsy. | James Morgan Mariana Alves Giorgia Conte Aida Menendez-Mendez Laura de Diego-Garcia Gioacchino de Leo Edward Beamer Jonathon Smith Annette Nicke Tobias Engel | 2020 | Neuroscience Bulletin2020，36，11： | 3 |

| 20 | P2X7 receptor signaling during adult hippocampal neurogenesis显示文摘Neurogenesis is a persistent and essential feature of the adult mammalian hippocampus.Granular neurons generated from resident pools of stem or progenitor cells provide a mechanism for the formation and consolidation of new memories.Regulation of hippocampal neurogenesis is complex and multifaceted,and numerous signaling pathways converge to modulate cell proliferation,apoptosis,and clearance of cellular debris,as well as synaptic integration of newborn immature neurons.The expression of functional P2X7 receptors in the central nervous system has attracted much interest and the regulatory role of this purinergic receptor during adult neurogenesis has only recently begun to be explored.P2X7 receptors are exceptionally versatile:in their canonical role they act as adenosine triphosphate-gated calcium channels and facilitate calcium-signaling cascades exerting control over the cell via calcium-encoded sensory proteins and transcription factor activation.P2X7 also mediates transmembrane pore formation to regulate cytokine release and facilitate extracellular communication,and when persistently stimulated by high extracellular adenosine triphosphate levels large P2X7 pores form,which induce apoptotic cell death through cytosolic ion dysregulation.Lastly,as a scavenger receptor P2X7 directly facilitates phagocytosis of the cellular debris that arises during neurogenesis,as well as during some disease states.Understanding how P2X7 receptors regulate the physiology of stem and progenitor cells in the adult hippocampus is an important step towards developing useful therapeutic models for regenerative medicine.This review considers the relevant aspects of adult hippocampal neurogenesis and explores how P2X7 receptor activity may influence the molecular physiology of the hippocampus,and neural stem and progenitor cells. | Hannah C.
