Cisplatin is an important chemotherapeutic agent; however, its nephrotoxicity limits its clinical use. Enhanced inflammatory response and oxidative/nitrosative stress seem to play a key role in the development of cisplatin-induced nephropathy. Activation of cannabinoid-2 (CB2) receptors with selective agonists exerts anti-inflammatory and tissue-protective effects in various disease models. We have investigated the role of CB2 receptors in cisplatin-induced nephrotoxicity using the selective CB2 receptor agonist HU-308 and CB2 knockout mice. Cisplatin significantly increased inflammation (leukocyte infiltration, CXCL1/2, MCP-1, TNFα, and IL-1β levels) and expression of adhesion molecule ICAM-1 and superoxide-generating enzymes NOX2, NOX4, and NOX1 and enhanced ROS generation, iNOS expression, nitrotyrosine formation, and apoptotic and poly(ADP-ribose) polymerase-dependent cell death in the kidneys of mice, associated with marked histopathological damage and impaired renal function (elevated serum BUN and creatinine levels) 3 days after the administration of the drug. CB2 agonist attenuated the cisplatin-induced inflammatory response, oxidative/nitrosative stress, and cell death in the kidney and improved renal function, whereas CB2 knockouts developed enhanced inflammation and tissue injury. Thus, the endocannabinoid system, through CB2 receptors, protects against cisplatin-induced kidney damage by attenuating inflammation and oxidative/nitrosative stress, and selective CB2 agonists may represent a promising novel approach to preventing this devastating complication of chemotherapy. 相似文献

Kidney is one of the most important organs in maintaining the normal life activities. With the high abundance of mitochondria, renal tubular cell plays the vital role in functioning in the reabsorption and secretion of kidney. Reports have shown that mitochondrial dysfunction is of great importance to renal tubular cell senescence and subsequent kidney ageing. However, the underlying mechanisms are not elucidated. Cannabinoid receptor 2 is one of the two receptors responsible for the activation of endocannabinoid system. CB2 is primarily upregulated in renal tubular cells in chronic kidney diseases and mediates fibrogenesis. However, the role of CB2 in tubular mitochondrial dysfunction and kidney ageing has not been clarified. In this study, we found that CB2 was upregulated in kidneys in 24-month-old mice and d -galactose (d -gal)-induced accelerated ageing mice, accompanied by the decrease in mitochondrial mass. Furthermore, gene deletion of CB2 in d -gal-treated mice could greatly inhibit the activation of β-catenin signalling and restore the mitochondrial integrity and Adenosine triphosphate (ATP) production. In CB2 knockout mice, renal tubular cell senescence and kidney fibrosis were also significantly inhibited. CB2 overexpression or activation by the agonist AM1241 could sufficiently induce the decrease in PGC-1α and a variety of mitochondria-related proteins and trigger cellular senescence in cultured human renal proximal tubular cells. CB2-activated mitochondrial dysfunction and cellular senescence could be blocked by ICG-001, a blocker for β-catenin signalling. These results show CB2 plays a central role in renal tubular mitochondrial dysfunction and kidney ageing. The intrinsic mechanism may be related to its activation in β-catenin signalling. 相似文献

Previous research from our laboratory has demonstrated a novel phenomenon whereby GPCRs play a role in inhibiting cytokine-mediated c-Jun N-terminal kinase (JNK) signalling. So far this novel phenomenon seems to have been vastly overlooked, with little research in the area. Therefore, in this study we explored this further; by assessing the potential of P2YRs to mediate inhibition of cytokine-mediated JNK signalling and related functional outcomes in human endothelial cells. We utilised primary endothelial cells, and employed the use of endogenous activators of P2YRs and well characterised pharmacological inhibitors, to assess signalling parameters mediated by P2YRs, Interleukin-1β (IL-1β), TNFα and JNK. Activation of P2YRs with adenosine tri-phosphate (ATP) resulted in a time- and concentration-dependent inhibition of IL-1β-mediated phosphorylation of JNK and associated kinase activity. The effect was specific for cytokine-mediated JNK signalling, as ATP was without effect on JNK induced by other non-specific activators (e.g. sorbitol, anisomycin), nor effective against other MAPK pathways such as p38 and the canonical NFκB cascade. Pharmacological studies demonstrated a role for the P2Y11 receptor in mediating this effect, but not the P2Y1 nor the adenosine receptors (A1, A2A, A2B & A3). The novel Gαq/11 inhibitor YM254890 and a protein kinase A (PKA) inhibitor H89 both partially reversed ATP-mediated inhibition of IL-1β-stimulated JNK indicating involvement of both Gαq/11 and Gαs mediated pathways. ATP also partially reversed IL-1β-mediated induction of cyclo‑oxygenase-2 (COX-2) and E-selectin. Collectively, these studies indicate the potential for activation of purinergic receptors to protect the endothelium from inflammatory driven JNK activation and may be a new target for inflammatory disease therapy. 相似文献

Cyst growth and expansion in autosomal dominant polycystic kidney disease (ADPKD) has been attributed to numerous factors, including ATP, cAMP and adenosine signalling. Although the role of ATP and cAMP has been widely investigated in PKD1-deficient cells, no information is currently available on adenosine-mediated signalling. Here we investigate for the first time the impact of abnormalities of polycystin-1 (PC1) on the expression and functional activity of adenosine receptors, members of the G-protein-coupled receptor superfamily. Pharmacological, molecular and biochemical findings show that a siRNA-dependent PC1-depletion in HEK293 cells and a PKD1-nonsense mutation in cyst-derived cell lines result in increased expression of the A3 adenosine receptor via an NFkB-dependent mechanism. Interestingly, A3 adenosine receptor levels result higher in ADPKD than in normal renal tissues. Furthermore, the stimulation of this receptor subtype with the selective agonist Cl-IB-MECA causes a reduction in both cytosolic cAMP and cell proliferation in both PC1-deficient HEK293 cells and cystic cells. This reduction is associated with increased expression of p21waf and reduced activation not only of ERK1/2, but also of S6 kinase, the main target of mTOR signalling. In the light of these findings, the ability of Cl-IB-MECA to reduce disease progression in ADPKD should be further investigated. Moreover, our results suggest that NFkB, which is markedly activated in PC1-deficient and cystic cells, plays an important role in modulating A3AR expression in cystic cells. 相似文献

Purinergic receptors, also known as purinoceptors, are ligand gated membrane ion channels involved in many cellular functions. Among all identified purinergic receptors, P2X7 subform is unique since it induces the caspase activity, cytokine secretion, and apoptosis. The distribution of P2X7 receptors, and the need of high concentration of ATP required to activate this receptor exhibited its ability to function as ‘danger’ sensor associated with tissue inflammation and damage. Further, the modulation of other signalling pathways associated with P2X7 has also been proposed to play an important role in the control of macrophage functions and inflammatory responses, especially towards lipopolysaccharides. Experimentally, researchers have also observed the decreased severity of inflammatory responses in P2X7 receptor expressing gene (P2RX7) knockout (KO) phenotypes. Therefore, newly developed potent antagonists of P2X7 receptor would serve as novel therapeutic agents to combat various inflammatory conditions. In this review article, we tried to explore various aspects of P2X7 receptors including therapeutic potential, and recent discoveries and developments of P2X7 receptor antagonists. 相似文献

Diabetic nephropathy is a leading cause for the development of end-stage renal disease. In diabetes mellitus, a number of structural changes occur within the kidney which leads to a decline in renal function. Damage to the renal proximal tubule cells (PTCs) in diabetic nephropathy includes thickening of the basement membrane, tubular fibrosis, tubular lesions and hypertrophy. A clearer understanding of the molecular mechanisms involved in the development of diabetic kidney disease is essential for the understanding of the role cellular pathways play in its pathophysiology. The endocannabinoid system is an endogenous lipid signalling system which is involved in lipogenesis, adipogenesis, inflammation and glucose metabolism. Recent studies have demonstrated that in diabetic nephropathy, there is altered expression of the endocannabinoid system. Future investigations should clarify the role of the endocannabinoid system in the development of diabetic nephropathy and within this system, identify potential therapeutics to reduce the burden of this disease. 相似文献

Sodium balance determines the extracellular fluid volume and sets arterial blood pressure (BP). Chronically raised BP (hypertension)
represents a major health risk in Western societies. The relationship between BP and renal sodium excretion (the pressure/natriuresis
relationship) represents the key element in defining the BP homeostatic set point. The renin–angiotensin–aldosterone system
(RAAS) makes major adjustments to the rates of renal sodium secretion, but this system works slowly over a period of hours
to days. More rapid adjustments can be made by the sympathetic nervous system, although the kidney can function well without
sympathetic nerves. Attention has now focussed on regulatory mechanisms within the kidney, including extracellular nucleotides
and the P2 receptor system. Here, we discuss how extracellular ATP can control renal sodium excretion by altering the activity
of epithelial sodium channels (ENaC) present in the apical membrane of principal cells. There remains considerable controversy
over the molecular targets for released ATP, although the P2Y2 receptor has received much attention. We review the available data and reflect on our own findings in which ATP-activated
P2Y and P2X receptors make adjustments to ENaC activity and therefore sodium excretion. 相似文献

The cytosolic pattern recognition receptor NOD2 is activated by the peptidoglycan fragment muramyl dipeptide to generate a proinflammatory immune response. Downstream effects include the secretion of cytokines such as interleukin 8, the upregulation of pro-interleukin 1β, the induction of autophagy, the production of antimicrobial peptides and defensins, and contributions to the maintenance of the composition of the intestinal microbiota. Polymorphisms in NOD2 are the cause of the inflammatory disorder Blau syndrome and act as susceptibility factors for the inflammatory bowel condition Crohn''s disease. The complexity of NOD2 signalling is highlighted by the observation that over 30 cellular proteins interact with NOD2 directly and influence or regulate its functional activity. Previously, the majority of reviews on NOD2 function have focused upon the role of NOD2 in inflammatory disease or in its interaction with and response to microbes. However, the functionality of NOD2 is underpinned by its biochemical interactions. Consequently, in this review, we have taken the opportunity to address the more ‘basic’ elements of NOD2 signalling. In particular, we have focused upon the core interactions of NOD2 with protein factors that influence and modulate the signal transduction pathways involved in NOD2 signalling. Further, where information exists, such as in relation to the role of RIP2, we have drawn comparison with the closely related, but functionally discrete, pattern recognition receptor NOD1. Overall, we provide a comprehensive resource targeted at understanding the complexities of NOD2 signalling. 相似文献

Roles of P2 receptors in glial cells: focus on astrocytes 总被引:1,自引:0,他引:1
Central nervous system glial cells release and respond to nucleotides under both physiological and pathological conditions, suggesting that these molecules play key roles in both normal brain function and in repair after damage. In particular, ATP released from astrocytes activates P2 receptors on astrocytes and other brain cells, allowing a form of homotypic and heterotypic signalling, which also involves microglia, neurons and oligodendrocytes. Multiple P2X and P2Y receptors are expressed by both astrocytes and microglia; however, these receptors are differentially recruited by nucleotides, depending upon specific pathophysiological conditions, and also mediate the long-term trophic changes of these cells during inflammatory gliosis. In astrocytes, P2-receptor-induced gliosis occurs via activation of the extracellular-regulated kinases (ERK) and protein kinase B/Akt pathways and involves induction of inflammatory and anti-inflammatory genes, cyclins, adhesion and antiapoptotic molecules. While astrocytic P2Y1 and P2Y2,4 are primarily involved in short-term calcium-dependent signalling, multiple P2 receptor subtypes seem to cooperate to astrocytic long-term changes. Conversely, in microglia, exposure to inflammatory and immunological stimuli results in differential functional changes of distinct P2 receptors, suggesting highly specific roles in acquisition of the activated phenotype. We believe that nucleotide-induced activation of astrocytes and microglia may originally start as a defence mechanism to protect neurons from cytotoxic and ischaemic insults; dysregulation of this process in chronic inflammatory diseases eventually results in neuronal cell damage and loss. On this basis, full elucidation of the specific roles of P2 receptors in these cells may help exploit the beneficial neuroprotective features of activated glia while attenuating their harmful properties and thus provide the basis for novel neuroprotective strategies that specifically target the purinergic system. 相似文献

Impaired mineral homeostasis and inflammation are hallmarks of chronic kidney disease (CKD), yet the underlying mechanisms of electrolyte regulation during CKD are still unclear. Here, we applied two different murine models, partial nephrectomy and adenine-enriched dietary intervention, to induce kidney failure and to investigate the subsequent impact on systemic and local renal factors involved in Ca2+ and Pi regulation. Our results demonstrated that both experimental models induce features of CKD, as reflected by uremia, and elevated renal neutrophil gelatinase-associated lipocalin (NGAL) expression. In our model kidney failure was associated with polyuria, hypercalcemia and elevated urinary Ca2+ excretion. In accordance, CKD augmented systemic PTH and affected the FGF23-αklotho-vitamin-D axis by elevating circulatory FGF23 levels and reducing renal αklotho expression. Interestingly, renal FGF23 expression was also induced by inflammatory stimuli directly. Renal expression of Cyp27b1, but not Cyp24a1, and blood levels of 1,25-dihydroxy vitamin D3 were significantly elevated in both models. Furthermore, kidney failure was characterized by enhanced renal expression of the transient receptor potential cation channel subfamily V member 5 (TRPV5), calbindin-D28k, and sodium-dependent Pi transporter type 2b (NaPi2b), whereas the renal expression of sodium-dependent Pi transporter type 2a (NaPi2a) and type 3 (PIT2) were reduced. Together, our data indicates two different models of experimental kidney failure comparably associate with disturbed FGF23-αklotho-vitamin-D signalling and a deregulated electrolyte homeostasis. Moreover, this study identifies local tubular, possibly inflammation- or PTH- and/or FGF23-associated, adaptive mechanisms, impacting on Ca2+/Pi homeostasis, hence enabling new opportunities to target electrolyte disturbances that emerge as a consequence of CKD development. 相似文献

Many previous studies have demonstrated that P2X7 receptors (P2X7Rs) have a pleiotropic function in different pathological conditions and could represent a novel target for the treatment of a range of diseases. In particular, recent studies have explored the role of P2X7R in fibrosis, the pathological outcome of most chronic inflammatory diseases. The aim of this review is to discuss the biological features of P2X7R and summarize the current knowledge about the putative role of the P2X7R in triggering fibrosis in a wide spectrum of organs such as the lung, kidney, liver, pancreas, and heart. 相似文献

The G protein-coupled P2Y2 receptor, activated by ATP and UTP has been reported as a potential drug target for a wide range of important clinical conditions, such as tumor metastasis, kidney disorders, and in the treatment of inflammatory conditions. However, pharmacological studies on this receptor have been impeded by the limited reported availability of stable, potent and selective P2Y2R antagonists. This article describes the design and synthesis of AR-C118925, a potent and selective non-nucleotide antagonist of the P2Y2 receptor discovered using the endogenous P2Y2R agonist UTP as the chemical starting point. 相似文献

The last 10 years has witnessed an explosion in research into roles of cilia in cystic renal disease. Cilia are membrane-enclosed finger-like projections from the cell, usually on the apical surface or facing into a lumen, duct or airway. Ten years ago, the major recognised functions related to classical “9 + 2” cilia in the respiratory and reproductive tracts, where co-ordinated beating clears secretions and assists fertilisation respectively. Primary cilia, which have a “9 + 0” arrangement lacking the central microtubules, were anatomical curiosities but several lines of evidence have implicated them in both true polycystic kidney disease and other cystic renal conditions: ranging from the homology between Caenorhabditis elegans proteins expressed on sensory cilia to mammalian polycystic kidney disease (PKD) 1 and 2 proteins, through the discovery that orpk cystic mice have structurally abnormal cilia to numerous recent studies wherein expression of nearly all cyst-associated proteins has been reported in the cilia or its basal body. Functional studies implicate primary cilia in mechanosensation, photoreception and chemosensation but it is the first of these which appears most important in polycystic kidney disease: in the simplest model, fluid flow across the apical surface of renal cells bends the cilia and induces calcium influx, and this is perturbed in polycystic kidney disease. Downstream effects include changes in cell differentiation and polarity. Pathways such as hedgehog and Wnt signalling may also be regulated by cilia. These data support important roles for cilia in the pathogenesis of cystic kidney diseases but one must not forget that the classic polycystic kidney disease proteins are expressed in several other locations where they may have equally important roles, such as in cell-cell and cell-matrix interactions, whilst it is not just aberrant cilia signalling that can lead to de-differentiation, loss of polarity and other characteristic features of polycystic kidney disease. Understanding how cilia fit into the other aspects of polycystic kidney disease biology is the challenge for the next decade.

BackgroundRenal fibrosis is the final manifestation of chronic kidney disease (CKD). Renal fibrosis is largely driven by oxidative stress and inflammation.PurposeThe aim of the current study was to identify novel poricoic acids from Poria cocos and investigated their antifibrotic effects and the underlying mechanism.MethodsIn this study, we identified six novel poricoic acids from Poria cocos and examined their antifibrotic effect using transforming growth factor-β1- (TGF-β1-) induced cultured human kidney proximal tubular epithelial cells (HK-2) and mice with unilateral ureteral obstruction (UUO).ResultsTreatment with six poricoic acids significantly inhibited TGF-β1-induced α-smooth muscle actin expression at both mRNA and protein levels in HK-2 cells. Three compounds with an intact carboxyl group at C-3 position showed a stronger inhibitory effect than that of other three compounds with esterified carboxyl group at the C-3 position. Mechanistically, poricoic acid ZM (PZM) and poricoic acid ZP (PZP) attenuate renal fibrosis through the modulation of redox signalling including the inhibition of proinflammatory nuclear factor kappa B (NF-κB) signalling and its target genes as well as the activation of antioxidative nuclear factor-erythroid-2-related factor 2 (Nrf2) signalling and its downstream target gene in both TGF-β1-induced HK-2 cells and UUO mice. PZM treatment and PZP treatment inhibit the upregulated aryl hydrocarbon receptor and they target the gene expression in UUO mice. Intriguingly, PZM treatment exhibits a stronger inhibitory effect than that of the PZP treatment. Structure–function relationship reveals that the carboxyl group at C-3 position is the most important bioactive function group in secolanostane tetracyclic triterpenoids against renal fibrosis.ConclusionsPZM and PZP attenuated renal fibrosis through the modulation of redox signalling and the aryl hydrocarbon receptor signalling pathway. Our findings will provide several promising leading compounds against renal fibrosis. 相似文献

The P2X7 purinoceptor is unique amongst the P2X receptor family in that its activation is able to stimulate the release of mature,
biologically active interleukin-1β (IL-1β), as well as a variety of other proinflammatory cytokines. Coupled with the predominate
localisation of this receptor to immunocytes of haemopoetic origin, this receptor is an obvious candidate to play a major
and pivotal role in processes of pain and inflammation. Using genetically modified animals that lack the P2X7 receptor, several investigators have shown that these mice do indeed demonstrate a blunted inflammatory response, and fail
to develop pain following both inflammatory and neuropathic insult. These animals also show altered cytokine production in
response to inflammatory stimulus, which is far broader than merely modulation of IL-1β release. In this short article, we
review the role of the P2X7 receptor in modulating the release of cytokines and other mediators, and discuss the findings made from P2X7 receptor-deficient animals. As well as highlighting outstanding questions regarding this intriguing receptor, we also speculate
as to the potential therapeutic benefit of P2X7 receptor modulation. 相似文献

Extracellular adenosine triphosphate (ATP) and its receptor, P2X7 receptor (P2X7R), are playing an important role in the pathological process of renal ischemia-reperfusion injury, but their underlying mechanism remains unclear. Also, the effects of tubular epithelium-expressed P2X7 receptor on ischemia acute kidney injury is still unknown. The aim of this study is to clarify if this mechanism involves the activation of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome in the renal tubular epithelial cells. In our research, we used male C57BL/6 wild type and P2X7R (−/−) mice, cultured human proximal tubular epithelial cells, and kidneys from acute kidney injury patients. Mice underwent for unilateral nephrectomy combined with the lateral renal pedicle clamping. Cultured cells were subjected to hypoxia/reoxygenation or ATP. Apyrase and A438079 were used to block the extracellular ATP/P2X7 receptor pathway. We also constructed radiation-induced bone marrow (BM) chimeras by using P2X7R (−/−) mice and P2X7R (+/+) wild-type mice. P2X7 receptor deficiency protected from renal ischemia-reperfusion injury and attenuated the formation of NLRP3 inflammasome. By using BM chimeras, we found a partial reduction of serum creatinine and less histological impairment in group wild-type BM to P2X7R (−/−) recipient, compared with group wild-type BM to wild-type recipient. In renal tubular epithelial cells, hypoxia/reoxygenation induced ATP release and extracellular ATP depletion reduced the expression of active IL-1β. ATP activated the NLRP3 inflammasome in renal tubular epithelial cells, which were blunted by transient silence of P2X7 receptor, as well as by P2X7 receptor blocking with A438079. In human samples, we found that patients with Stage 3 AKI had higher levels of P2X7 receptor expression than patients with Stage 1 or Stage 2. Extracellular ATP/P2X7 receptor axis blocking may protect renal tubular epithelial cells from ischemia-reperfusion injury through the regulation of NLRP3 inflammasome.Subject terms: Membrane proteins, Mechanisms of disease, Acute kidney injury 相似文献

Hypertension is the leading cause of morbidity and mortality globally among all cardiovascular diseases. Purinergic signalling plays a crucial role in hypertension through the sympathetic nerve system, neurons in the brain stem, carotid body, endothelium, immune system, renin-angiotensin system, sodium excretion, epithelial sodium channel activity (ENaC), and renal autoregulation. Under hypertension, adenosine triphosphate (ATP) is released as a cotransmitter from the sympathetic nerve. It mediates vascular tone mainly through P2X1R activation on smooth muscle cells and activation of P2X4R and P2YR on endothelial cells and also via interaction with other purinoceptors, showing dual effects. P2Y1R is linked to neurogenic hypertension. P2X7R and P2Y11R are potential targets for immune-related hypertension. P2X3R located on the carotid body is the most promising novel therapeutic target for hypertension. A1R, A2AR, A2BR, and P2X7R are all related to renal autoregulation, which contribute to both renal damage and hypertension. The main focus is on the evidence addressing the involvement of purinoceptors in hypertension and therapeutic interventions. 相似文献
