Abstract
Lipopolysaccharide (LPS) is known to elicit a robust immune response. This study aimed to investigate the impact of LPS on the transcriptome of human nasal epithelial cells (HNEpC). HNEpC were cultured and stimulated with LPS (1 μg/mL) or an equivalent amount of normal culture medium. Subsequently, total RNA was extracted, purified, and sequenced using next-generation RNA sequencing technology. Differentially expressed genes (DEGs) were identified and subjected to functional enrichment analysis. A protein-protein interaction (PPI) network of DEGs was constructed, followed by Ingenuity Pathway Analysis (IPA) to identify molecular pathways influenced by LPS exposure on HNEpC. Validation of key genes was performed using quantitative real-time PCR (qRT-PCR). A total of 97 DEGs, comprising 48 up-regulated genes and 49 down-regulated genes, were identified. Results from functional enrichment analysis, PPI, and IPA indicated that DEGs were predominantly enriched in chemokine-related signaling pathways. Subsequent qRT-PCR validation demonstrated significant upregulation of key genes in these pathways in LPS-treated HNEpC compared to control cells. In conclusion, LPS intervention profoundly altered the transcriptome of HNEpC, potentially exacerbating inflammatory responses through the activation of chemokine-related signaling pathways.

Platycodon D protects human nasal epithelial cells from pyroptosis through the Nrf2/HO-1/ROS signaling cascade in chronic rhinosinusitis. Chin Med 2024; 19:40. [PMID: 38433216 PMCID: PMC10910709 DOI: 10.1186/s13020-024-00897-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 01/28/2024] [Indexed: 03/05/2024] Open
Abstract
BACKGROUND Pyroptosis has been demonstrated being closely associated with the inflammatory progression in chronic rhinosinusitis (CRS). However, platycodon D (PLD) has emerged as a key anti-inflammatory mediator in the inflammatory progression of various respiratory diseases. This study aims at investigating whether PLD could reduce inflammatory progression of CRS by inhibiting pyroptosis. METHODS Nasal mucosal tissues from patients with CRS and the control group (simple nasal septal deviation) were analyzed for morphological difference using hematoxylin & eosin staining and for the expression of pyroptosis-related makers by immunofluorescence (IF). Human nasal epithelial cells (HNEpCs) were cultured and co-stimulated with lipopolysaccharide (LPS)/adenosine triphosphate (ATP) to construct an in vitro cellular model simulating CRS. After pretreatment with PLD, EthD-I staining, TUNEL staining, transmission electron microscopy (TEM), and GSDMD-NT detection were performed to evaluate pyroptosis markers. The NLRP3 inflammasome was detected by IF and western blotting (WB). Reactive oxygen species (ROS) were detected by H2DCFDA staining, and mitochondrial membrane potential was evaluated by JC-1 staining. Mitochondrial morphology and structure were observed using TEM. The Nrf2/HO-1 antioxidant signaling pathway was detected using WB. RESULTS The nasal mucosa structure of patients with CRS exhibited significant damage, with a marked increase in the expression of pyroptosis-related proteins compared with the control group. LPS/ATP co-stimulation resulted in an increased expression of IL-18 and IL-1β in HNEpCs, causing significant damage to nuclear and cell membranes, GSDMD-NT accumulation around the cell membrane, and intracellular NLRP3 inflammasome activation. Furthermore, it led to increased ROS expression, significantly decreased mitochondrial membrane potential, and damaged mitochondrial structure. However, pretreatment with PLD significantly reversed the aforementioned trends and activated the Nrf2/HO-1 antioxidant signaling pathway. CONCLUSIONS The results of this study confirm that NLRP3-mediated pyroptosis plays a crucial role in the pathological process of nasal mucosal impairment in patients with CRS. PLD inhibits NLRP3-mediated pyroptosis, preventing inflammatory damage in HNEpCs of patients with CRS by activating the Nrf2/HO-1 antioxidant signaling pathway, which in turn reduces ROS production and ameliorates mitochondrial damage.

Abstract
INTRODUCTION Chronic rhinosinusitis with nasal polyps (CRSwNP) is an immunologic disease, and pyroptosis, an inflammation-based cellular death, strictly modulates CRSwNP pathology, whereas the pyroptosis genes and mechanisms involved in CRSwNP remain unclear. Herein, we explored disease biomarkers and potential therapeutic targets for pyroptosis and immune regulation in CRSwNP using bioinformatics analysis and tissue-based verification. METHODS We retrieved the transcriptional profiles of the high-throughput dataset GSE136825 from the Gene Expression Omnibus database, as well as 170 pyroptosis-related gene expressions from GeneCards. Using R, we identified differentially expressed pyroptosis-related genes and examined the potential biological functions of the aforementioned genes using Gene Ontology, Kyoto Encyclopedia of the Genome pathway, immune infiltration, and protein-protein interaction (PPI) network analyses, thereby generating a list of hub genes. The hub genes were, in turn, verified using real-time quantitative polymerase chain reaction (qRT-PCR), immunohistochemistry (IHC), and Western blotting (WB). Ultimately, using the StarBase and miRTarBase databases, we estimated the targeting microRNAs and long chain non-coding RNAs. RESULTS We demonstrated that the identified pyroptosis-related genes primarily modulated bacterial defense activities, as well as inflammasome immune response and assembly. Moreover, they were intricately linked to neutrophil and macrophage infiltration. Furthermore, we validated the tissue contents of hub genes AIM2, NLPR6, and CASP5 and examined potential associations with clinical variables. We also developed a competitive endogenous RNA (ceRNA) modulatory axis to examine possible underlying molecular mechanisms. CONCLUSION We found AIM2, CASP5, and NLRP6, three hub genes for pyroptosis in chronic rhinosinusitis with nasal polyps, by biological analysis, experimental validation, and clinical variable validation.

Abstract
BACKGROUND AND PURPOSE Cytokine storm invoked during acute and chronic lung injury promotes alveolar damage and remodeling. The current study shows that degraded elastin-targeted nanoparticles releasing doxycycline (Doxy NPs) are potent in mitigating cytokines storm, migration of immune cells in the lungs, and inhibiting inflammasome pathways in the LPS mouse model. EXPERIMENTAL APPROACH Cytokine storm and lung injury were induced using LPS and elastase in C57BL/6 mice (rodent model for emphysema). The mice were then treated with I.V. Doxy NPs, blank NPs, or Doxy a day before LPS administration. Cytokine levels, immune cell population, and MMP activity were analyzed in broncheo-alveolar lavage fluid (BALF) 4 hours after LPS administration. Additionally, gene expression of IL-6, IL-1beta, MCP-1, NLRP3, Caspase 1 and MMPs were investigated in alveolar cells on day 3 after LPS administration. KEY RESULTS Doxycycline NPs but not Doxycycline significantly decreased IL-6, TNF-α, IL-23 and were significantly more effective in decreasing the percentage of immune cells in the BALF. This is the first in-vivo study to demonstrate that Doxycycline can effectively inhibit inflammasome pathways in the lungs. CONCLUSION AND IMPLICATIONS IV administration of elastin antibody conjugated Doxycycline-loaded albumin NPs can effectively modulate the local immune environment in the lungs, which is not achieved by IV Doxycycline even at 100-fold higher dose. This novel method of drug delivery can effectively lead to the repurposing of traditional Doxycycline as a potential adjunct treatment for managing the cytokine storm in the lungs in COPD and viral infections.

Abstract
BACKGROUND Eosinophilic inflammation is a hallmark of refractory chronic rhinosinusitis (CRS) and considered a major therapeutic target. Autophagy deficiency in myeloid cells plays a causal role in eosinophilic CRS (ECRS) via macrophage IL-1β overproduction, thereby suggesting autophagy regulation as a potential therapeutic modality. Trehalose is a disaccharide sugar with known pro-autophagy activity and effective in alleviating diverse inflammatory diseases. We sought to investigate the therapeutic potential of autophagy-enhancing agent, trehalose, or related sugar compounds, and the underlying mechanism focusing on macrophage IL-1β production in ECRS pathogenesis. METHODS We investigated the therapeutic effects of trehalose and saccharin on macrophage IL-1β production and eosinophilia in the mouse model of ECRS with myeloid cell-specific autophagy-related gene 7 (Atg7) deletion. The mechanisms underlying their anti-inflammatory effects were assessed using specific inhibitor, genetic knockdown or knockout, and overexpression of cognate receptors. RESULTS Unexpectedly, trehalose significantly attenuated eosinophilia and disease pathogenesis in ECRS mice caused by autophagy deficiency in myeloid cells. This autophagy-independent effect was associated with reduced macrophage IL-1β expression. Various sugars recapitulated the anti-inflammatory effect of trehalose, and saccharin was particularly effective amongst other sugars. The mechanistic study revealed an involvement of sweet taste receptor (STR), especially T1R3, in alleviating macrophage IL-1β production and eosinophilia in CRS, which was supported by genetic depletion of T1R3 or overexpression of T1R2/T1R3 in macrophages and treatment with the T1R3 antagonist gurmarin. CONCLUSION Our results revealed a previously unappreciated anti-inflammatory effect of STR agonists, particularly trehalose and saccharin, and may provide an alternative strategy to autophagy modulation in the ECRS treatment.

Abstract
BACKGROUND The pathophysiologic mechanisms of human chronic rhinosinusitis (CRS) are highly complex, and sinonasal colonization with pathogens is the first and most important step in this process. NLRP3, the main receptor activated by pathogen-associated molecular patterns (PAMPs), is associated with a variety of inflammatory diseases, including airway inflammation; however, the understanding of its role in CRS is limited. OBJECTIVE By detecting the differential expression of the NLRP3 inflammasome and its downstream cytokines IL-1β and IL-18 between CRS patients and controls, between different CRS phenotypes (CRSsNP and CRSwNP), between mucosal tissue and polyp tissue, and further its relationship with neutrophilic/eosinic infiltration, we aimed to elucidate the biological role of the NLRP3 inflammasome in the pathophysiologic mechanisms of CRS. METHODS Fifteen cases in each control, CRSsNP, and CRSwNP groups (subdivided into mucosa tissue and polyp tissue) were included in this study. Differential expression of NLRP3/caspase-1 and its downstream cytokines IL-1β and IL-18 was investigated, and its relationship with neutrophilic and eosinophilic infiltration was analyzed. Fluorescent immunohistochemistry (F-IHC) was used to assess NLRP3 and caspase-1 expression, RT-PCR was used for mRNA level quantitation, and western blotting was employed to analyze the protein concentrations. RESULTS NLRP3 and cleaved caspase-1 were expressed at higher levels in both the CRSsNP and CRSwNP phenotypes than in the control nasal mucosa and at much higher levels in polyp tissue of CRSwNP (P < .05), which was in line with the expression of cleaved IL-1β and cleaved IL-18 (P < .05). Higher expression of NLRP3 had a mild correlation with neutrophilic infiltration but highly correlated with eosinophilic infiltration (R = 0.607, P < .01). CONCLUSIONS NLRP3 is involved in the pathogenesis of CRS, most likely by the NLRP3/caspase-1/IL-1β and IL-18 response. It induced eosinophilic infiltration in CRSwNP, especially in polyp tissue. As for whether NLRP3 induces neutrophilic infiltration, further experiments are needed to confirm.

Abstract
Povidone-iodine (PVP-I) is an antiseptic and a disinfectant with broad-spectrum antimicrobial activity against various pathogens. However, it is unclear whether PVP-I nasal instillation can suppress mucosal inflammation in non-eosinophilic chronic rhinosinusitis (CRS) mice. This study aimed to explore the anti-inflammatory effects and underlying molecular mechanism of PVP-I on lipopolysaccharide-stimulated airway epithelial cells and investigate whether nasal instillation of PVP-I can suppress mucosal inflammation in non-eosinophilic CRS mice. Inflammation-related molecules in the nasal epithelial cells and non-eosinophilic CRS mice were measured by enzyme-linked immunosorbent assay, western blotting, quantitative real-time polymerase chain reaction, immunoprecipitation, and histopathological analysis. PVP-I blocked expressions of various inflammation-related molecules, such as NLRP3, NF-κB-p65, caspase-1, and IL-1β. Translocation of NF-κB to the nucleus, and assembly of NLRP3/ASC complexes in the nasal epithelial cells and non-eosinophilic CRS mice were also restricted. Notably, PVP-I strongly blocked the receptor co-localization of TLR4 and MyD88 in the epithelial cells of nasal mucosa. We demonstrated that PVP-I significantly attenuated inflammatory molecules and cytokines via blocking the formation of TLR4 and MyD88 complexes during LPS-induced mucosal inflammation in non-eosinophilic CRS.

Abstract
Background Monogenic conditions that disrupt proper development and/or function of the immune system are termed inborn errors of immunity (IEIs), also known as primary immunodeficiencies. Patients with IEIs often suffer from other manifestations in addition to infection, and allergic inflammation is an increasingly recognized feature of these conditions. Methods We performed a retrospective analysis of IEIs presenting with allergic inflammation as reported in the USIDNET registry. Our inclusion criteria comprised of patients with a reported monogenic cause for IEI where reported lab eosinophil and/or IgE values were available for the patient prior to them receiving potentially curative therapy. Patients were excluded if we were unable to determine the defective gene underlying their IEI. Patients were classified as having eosinophilia or elevated IgE when their record included at least 1 eosinophil count or IgE value that was greater than the age stratified upper limit of normal. We compared the proportion of patients with eosinophilia or elevated IgE with the proportion of samples in a reference population that fall above the upper limit of normal (2.5%). Results The query submitted to the USIDNET registry identified 1409 patients meeting inclusion criteria with a monogenic cause for their IEI diagnosis, of which 975 had eosinophil counts and 645 had IgE levels obtained prior to transplantation or gene therapy that were available for analysis. Overall, 18.8% (183/975) of the patients evaluated from the USIDNET registry had eosinophilia and 20.9% (135/645) had an elevated IgE. IEIs caused by defects in 32 genes were found to be significantly associated with eosinophilia and/or an elevated IgE level, spanning 7 of the 10 IEI categories according to the International Union of Immunological Societies classification. Conclusion Type 2 inflammation manifesting as eosinophilia or elevated IgE is found in a broad range of IEIs in the USIDNET registry. Our findings suggest that allergic immune dysregulation may be more widespread in IEIs than previously reported.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammation‑mediated disease of the nasal mucosa. P2X7R has been reported to be a potential biomarker for inflammation. The aim of the present study was to explore the role of P2X7R in CRSwNP, and the interaction between P2X7R and the NLRP3 inflammasome in the development of CRSwNP. Firstly, the expression profiles of P2X7R in nasal mucosa were investigated using western blotting (WB), polymerase chain reaction (PCR) and immunofluorescence (IF) staining. Next, the effect of inflammatory stimulation with lipopolysaccharides (LPS) combined with 2'(3')‑O‑(4‑benzoylbenzoyl) adenosine 5'‑triphosphate triethylammonium salt (BzATP) on primary human nasal epithelial cells (HNECs) was determined. Then, the therapeutic effect of the selective P2X7R antagonist, A740003, on P3X7R, NOD‑like receptor pyrin domain containing 3 (NLRP3) inflammasome and IL‑1β alterations in HNECs was explored using enzyme‑linked immunosorbent assay, WB and PCR. It was found that P2X7R was overexpressed in CRSwNP, especially in eosinophilic CRSwNP, the expression of P2X7R, NLRP3 and IL‑1β were upregulated in HNECs after induction by LPS combined with BzATP; but the expression of NLRP3 and IL‑1β were downregulated after stimulation with A740003. The aforementioned results indicate that P2X7R‑mediated NLRP3 inflammasome activation may have a role in the pathogenesis of CRSwNP.

Abstract
OBJECTIVE Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by a chronic type 2 inflammatory response in the paranasal sinuses. Group 2 innate lymphoid cells (ILC2s) are potent innate immune cells that contribute to type 2 inflammation by producing cytokines such as interleukin (IL)-4, IL-5, and IL-13. There is increasing evidence suggesting that ILC2s play an important role in the CRSwNP pathogenesis. DATA SOURCES We reviewed published literature obtained through PubMed inquiries. STUDY SELECTIONS Studies relevant to the presence, function, and activation of ILC2s in CRSwNP were included. RESULTS Nasal polyps (NPs) are one of the first tissues in which human ILC2s were discovered, and many groups have since reported that these cells are highly elevated in NPs. ILC2s in NPs are also highly activated and produce type 2 cytokines in vivo. Mediators known to activate ILC2s, including receptor activator of nuclear factor kappa-Β ligand, thymic stromal lymphopoietin, various lipid mediators (including prostaglandin D2 and cysteinyl leukotrienes), IL-4, and IL-13 have also been shown to be elevated in NPs compared with healthy sinonasal tissue. Other well-known ILC2 activators, IL-25 and IL-33, are sometimes elevated in NPs in some countries. Furthermore, activation of ILC2s by means of 4 distinct transcriptional pathways (nuclear factor kappa-light-chain-enhancer of activated B cells, nuclear factor of activated T cells, signal transducer and activator of transcription 5, and signal transducer and activator of transcription 6) is needed for the most robust generation of type 2 cytokines. CONCLUSION ILC2-mediated type 2 inflammation plays a crucial role in the pathogenesis of CRSwNP. Targeting the upstream mediators responsible for activating ILC2s and the downstream products that these cells release may play an important role in modifying the inflammatory response and improving clinical outcomes in CRSwNP.

Abstract
BACKGROUND At present, the effect of operation intervention on pulmonary function is not clear in patients with allergic rhinitis and chronic rhinosinusitis with nasal polyps (AR&CRSwNP). This study was conducted to investigate the effect of vidian neurectomy on pulmonary function and airway hyperresponsiveness (AHR) in patients with AR&CRSwNP. METHODS The incidences of AHR, bronchial asthma (BA) and pulmonary function impairment in 112 patients with AR&CRSwNP were investigated. Subsequently, we evaluated the outcome of vidian neurectomy and its effect on pulmonary function and AHR. Furthermore, we explored the correlation between postoperative level of eosinophilic cationic protein (ECP) and the changes of pulmonary function indices or dose of methacholine. RESULTS In this study, the incidences of pulmonary function impairment, bronchial asthma, and AHR in patients with AR&CRSwNP were 61.61%, 69.64%, and 66.96%, respectively. Particularly, vidian neurectomy effectively alleviated nasal symptoms, improved pulmonary function, and reduced AHR in AR&CRSwNP patients. Furthermore, the postoperative level of ECP, IgE, Interleukin-4 and Interleukin-IL-5 was dramatically decreased, and there was an obvious inverse correlation between ECP level and pulmonary function index or dose of methacholine. CONCLUSIONS Vidian neurectomy is effective in alleviating nasal symptoms, improving pulmonary function, and reducing the risk of AHR of patients with AR&CRSwNP by decreasing the level of ECP.

Abstract
Allergic rhinitis, chronic rhinosinusitis, and asthma are highly prevalent, multifactorial chronic airway diseases. Several environmental and genetic factors affect airway epithelial dynamics leading to activation of inflammatory mechanisms in the airways. This review links environmental factors to host epithelial immunity in airway diseases. Understanding altered homeostasis of the airway epithelium might provide important targets for diagnostics and therapy of chronic airway diseases.

Abstract
Allergic rhinitis (AR) is a complex IgE-mediated nasal allergic and inflammatory disease. Nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) is essential in the process of allergic and inflammatory responses. MCC950 is a selective NLRP3 inhibitor. However, its role and mechanism in AR remains undetermined. The present study aimed to explore the effect and mechanism of MCC950 on an ovalbumin (OVA) induced mouse model of AR. The AR BALB/c mice were constructed using OVA and administrated intranasally with MCC950. Concentrations of OVA-specific IgE, histamines and leukotrienes C4 (LTC4) in serum, and OVA-specific IgE, ECP, IFN-γ, IL-4, IL-5, IL-13, IL-1β and IL-18 in nasal lavage fluid (NLF) were assayed by enzyme-linked immunosorbent assay (ELISA). Inflammatory cells were counted in NLF. HE and PAS staing were used for evaluating eosinophils and goblet cells. Immunohistochemistry (IHC) staining were employed to evaluate immunolabeling of NLRP3, Caspase-1, ASC, IL-1β and IL-18 in nasal mucosas of mice. Real-time PCR was conducted to assay NLRP3, Caspase-1, ASC, IL-1β and IL-18 mRNA levels. In vitro studies, western blotting, real-time PCR and ELISA were performed to evaluate the effects and mechanisms of OVA and NLRP3 inhibitor MCC950 on spleen mononuclear cells. We found significant downregulation of sneezing, nasal rubbing, inflammatory cytokines, inflammatory cells and NLRP3, Caspase-1, ASC, IL-1β and IL-18 expression in MCC950 treated mice compared with untreated AR mice. In spleen mononuclear cells culture and stimulation experiment, NLRP3, Caspase-1, ASC, IL-1β and IL-18 levels were upregulated by OVA but inhibited by MCC950. In conclusion, MCC950 could effectively exert its ameliorative effect in murine AR by inhibiting NLRP3 and leads to reduction of Caspase-1, ASC, IL-1β and IL-18, resulting in the attenuation of the allergic and inflammatory responses.

Abstract
From the viewpoint of the general pathology, most of the human diseases are associated with a limited number of pathogenic processes such as inflammation, tumor growth, thrombosis, necrosis, fibrosis, atrophy, pathological hypertrophy, dysplasia and metaplasia. The phenomenon of chronic low-grade inflammation could be attributed to non-classical forms of inflammation, which include many neurodegenerative processes, pathological variants of insulin resistance, atherosclerosis, and other manifestations of the endothelial dysfunction. Individual and universal manifestations of cellular stress could be considered as a basic element of all these pathologies, which has both physiological and pathophysiological significance. The review examines the causes, main phenomena, developmental directions and outcomes of cellular stress using a phylogenetically conservative set of genes and their activation pathways, as well as tissue stress and its role in inflammatory and para-inflammatory processes. The main ways towards the realization of cellular stress and its functional blocks were outlined. The main stages of tissue stress and the classification of its typical manifestations, as well as its participation in the development of the classical and non-classical variants of the inflammatory process, were also described. The mechanisms of cellular and tissue stress are structured into the complex systems, which include networks that enable the exchange of information with multidirectional signaling pathways which together make these systems internally contradictory, and the result of their effects is often unpredictable. However, the possible solutions require new theoretical and methodological approaches, one of which includes the transition to integral criteria, which plausibly reflect the holistic image of these processes.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the most prevalent chronic diseases. In patients with CRSwNP, the present study performed comprehensive bioinformatics analyses to characterize the transcriptome profiles of mRNAs and long non‑coding RNAs (lncRNAs). A total of 265 differentially expressed lncRNAs and 994 mRNAs were identified. The majority of up‑ and downregulated differentially expressed genes were significantly enriched in the biological process of 'signal transduction'. The most significantly enriched molecular function was 'protein binding' and the most significantly enriched cellular component was 'membrane'. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis led to identification of several significantly enriched pathways [false discovery rate (FDR)<0.05], including 'cytokine‑cytokine receptor interaction' (FDR=3.94x1016) and 'cell adhesion molecules' (CAMs) (FDR=1.28x10‑5). Key differentially expressed lncRNAs were identified, including lncRNA XLOC_010280, which regulates chemokine (C‑C motif) ligand 18 (CCL18) and inflammation, and RP11‑798M19.6, which regulates polypeptide N‑acetylgalactosaminyltransferase 7 (GALNT7) and cell proliferation. Based on the results of reverse transcription‑quantitative polymerase chain reaction, except for CCL8, neural precursor cell expressed developmentally downregulated gene 4‑like and GALNT7, the expression of 3 other selected genes was consistent with the results of integrated analysis. The results of the present study provide a foundation for future investigations into mRNAs and lncRNAs as diagnostic and therapeutic targets in CRSwNP.

Abstract
BACKGROUND/OBJECTIVE The pathophysiological and prognostic role of blood inflammatory cells in chronic rhinosinusitis with nasal polyps (CRSwNP) emerging from recent studies was investigated. MATERIAL AND METHODS The main available evidence and largely-recent publications were critically analyzed. RESULTS Several authors reported a direct association between blood eosinophilia and CRSwNP recurrence rates. In some large series, a direct association between recurrent CRSwNP and blood basophil values emerged too. CRSwNP patients' blood eosinophil and basophil values were strongly related. It was also found that preoperative neutrophil-to-lymphocyte, eosinophil-to-lymphocyte, and basophil-to-lymphocyte ratios were significantly higher in patients who experienced a disease relapse than in those who did not. In histologically-confirmed eosinophilic-type CRSwNP treated with endoscopic sinus surgery, mean blood eosinophil values dropped significantly from before to after the surgical procedure. CONCLUSIONS/SIGNIFICANCE CRSwNP endotypes have different inflammatory profiles reflected in the relative proportions of different types of blood cells. The available data support the theory that blood eosinophil and basophil levels should be included in the routine preoperative work-up of CRSwNP patients in order to give patients accurate prognostic information, adopt rational follow-up protocols after surgery, and provide dedicated postoperative medical treatments.

Abstract
BACKGROUND The pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) has not been fully elucidated. This study sought to explore the role and mechanism of transient receptor potential canonical channel 6 (TRPC6) in the pathogenesis of CRSwNP. METHODS Immunohistochemistry (IHC) was employed to evaluate TRPC6 immunolabeling. Real-time polymerase chain reaction (PCR) was conducted to assay TRPC6, stromal interaction molecule 1 (STIM1), and calcium release-activated calcium channel protein 1 (Orai1) messenger RNA (mRNA) levels in 70 patients with CRSwNP, including eosinophilic CRSwNP (ECRSwNP) or non-eosinophilic CRSwNP (nECRSwNP), and 28 control subjects. The concentrations of inflammatory mediators, including interleukin (IL)-1β, IL-5, and IL-25, were assayed by enzyme-linked immunosorbent assay (ELISA). In experiments on human nasal epithelial cell (HNEC) culture and stimulation, the mean fluorescence intensity (MFI) of intracellular Ca2+ was assayed by flow cytometry. Western blotting, real-time PCR, and ELISA were also conducted to assess the effects and mechanisms of TRPC6 activator 1-oleoyl-2-acetyl-glycerol (OAG) and TRPC6 inhibitor 1-[2-(4-methoxyphenyl)-2-[3-(4-methoxyphenyl) propoxy]ethyl-1H-imidazole (SKF-96365) on HNECs. RESULTS Upregulation of TRPC6, STIM1, and Orai1 levels was found in CRSwNP patients, particularly in those with ECRSwNP. TRPC6-positive cells correlated positively with the numbers of eosinophils and neutrophils, respectively. Moreover, TRPC6 mRNA was positively correlated with STIM1 and Orai1 mRNA levels. The concentrations of inflammatory mediators, including IL-1β, IL-5, and IL-25, were elevated in CRSwNP, especially in ECRSwNP. In cultured HNECs, TRPC6, STIM1, Orai1, Ca2+ MFI levels, and inflammatory mediators were upregulated by lipopolysaccharide (LPS) and OAG but were inhibited by SKF-96365. CONCLUSION TRPC6 plays a pro-inflammatory role in the pathogenesis of CRSwNP via regulating Ca2+ flow.

Chen F, Wei G, Xu J, Ma X, Wang Q. Naringin ameliorates the high glucose-induced rat mesangial cell inflammatory reaction by modulating the NLRP3 Inflammasome. Altern Ther Health Med 2018; 18:192. [PMID: 29929501 PMCID: PMC6014005 DOI: 10.1186/s12906-018-2257-y] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Accepted: 06/13/2018] [Indexed: 01/01/2023]
Abstract
BACKGROUND The Nucleotide binding and oligomerization domain-like receptorfamily pyrin domain-containing 3 (NLRP3)-inflammasome plays an important role in various diseases, including a variety of kidney diseases. Naringin exhibits anti-inflammatory and anti-oxidation effects among others, but its specific mechanisms are not clear. We investigated the expression of the NLRP3-inflammasome under high-glucose conditions, assessed the effects of naringin on that process, and further elucidated the role of naringin in the pathogenesis of diabetic kidney disease(DKD). METHODS To assess the therapeutic potential of naringin and the mechanisms involved, we cultured rat glomerular mesangial cells and grouped them according to different glucose concentrations, different action times, different concentrations of MCC950, and different concentrations of naringin.The cell proliferation was measured by MTT assay. The expression of Interleukin-1β(IL-1β) and Interleukin18 (IL-18) in the cell supernatant were detected by ELISA. The expression and activity of NLPR3, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) and Caspase-1 were detected by Western Blot. RESULTS The expressions of NLRP3, ASC, caspase-1, IL-1β, and IL-18 in rat glomerular mesangial cells were significantly higher in the high glucose (HG) group than in the control normal glucose (NG) group and exhibited time-dependence activity. The expression levels of NLRP3, caspase-1, IL-1β, and IL-18 in different treatment groups were significantly lower compared with the HG group after 48 h of MCC950 pre-treatment (p < 0.05). Pre-treatment with naringin produced the same results. Naringin also inhibited the proliferation of cells. CONCLUSIONS The NLRP3-inflammasome potentially plays a role in the process of activation and inflammation of glomerular mesangial cells as induced by high-glucose conditions. Naringin inhibited the proliferation of cells that were induced by high glucose. Further, it reduced the expression of inflammatory factors that are mediated by NLRP3 through the NLRP3-caspase-1-IL-1β/IL-18 signaling pathway, which makes naringin a potentially novel treatment for DKD disease.

Abstract
The inflammasome complex is part of the innate immune system, which serves to protect the host against harm from pathogens and damaged cells. It is a term first proposed by Tschopp's group in 2002, with numerous original research articles and reviews published on the topic since. There have been many types of inflammasome identified, but all result in the common pathway of activation of caspases and interleukin 1β along with possible cell death called pyroptosis. Despite a growing body of research investigating the structure and function of the inflammasome in animal models, there is still limited evidence identifying inflammasome components in human physiology and disease. In this review, we explore the molecular structure and mechanism of activation of the inflammasome with a particular focus on inflammasome complexes expressed in humans. Inflammasome components have been identified in several human peripheral and brain tissues using both in vivo and ex vivo work, and the inflammasome complex has been shown to be associated with several genetic and acquired inflammatory and neoplastic disorders. We discuss the strengths and weaknesses of the information available on the inflammasome with an emphasis on the importance of prioritizing work on human tissue. There is a huge demand for more effective treatments for a number of inflammatory and neurodegenerative diseases. Modulation of the inflammasome has been proposed as a novel treatment for several of these diseases and there are currently clinical trials ongoing to test this theory.
