In recent years M2-like macrophages have been found to play an important role in the pathological process of RA by mediating pro-inflammatory effects, but their roles in the bone destruction of autoimmune arthritis have not been reported. In this study we identified that an abundant cell population of CD45+CD11b+Gr-1-F4/80+CD206+ cells, which were normally classified as M2-like macrophages, was present in synovium of collagen-induced arthritis (CIA) mice, and these cells had the potential to differentiate into osteoclasts. These M2-like macrophages sorted from CIA synovium highly expressed RANK and could be activated by RANKL and M-CSF to acquire osteoclast markers and bone resorption function both in vitro and in vivo. Furthermore, in vitro differentiated M2 macrophages from both CIA mouse bone marrow and RA patient peripheral blood mononuclear cells were also able to differentiate into osteoclasts, confirming the general osteoclastogenesis capability of M2 subtype macrophages. All these results suggest that synovial F4/80+CD206+ M2-like macrophages in RA may be novel osteoclast precursors and contribute significantly to bone erosive changes seen in RA. Our studies provided new directions and targets for the diagnosis and treatment of rheumatoid arthritis.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47107093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we describe a model of SLE pathogenesis in which the induction of an autoimmune response is based on mitochondrial antigens. In addition to options for initiating an autoimmune response involving mitochondrial components, the model describes the role of pathways and immune cells of these pathways of adaptive immunity in SLE, as well as factors leading to the development of chronic inflammation in SLE.

Methods: A total of 200 children with pneumonia combined with sepsis who attended the First People’s Hospital of Shangqiu from January 1, 2020 to February 13, 2022 were consecutively collected. Children were randomly divided into IN group and routine nursing (RN) group, with 100 children in each group. All children received standard anti-infection treatment along with intravenous HGG. In IN group, IN measures based on the IoT cloud computing platform monitored the treatment process of children with HGG throughout the whole process, while children in the RN group only received RN measures. Information on both groups was collected from the medical records, such as gender, age, duration of hospitalization, fever, antibiotic use, serological indicators, pulmonary function indicators, immune function indicators and adverse effects of HGG. Multi-factorial logistic regression was performed to access the correlation between IN and the duration of hospitalization and a range of other factors studied above. Results: After adjusting for numerous confounding factors, multifactorial logistic regression revealed that the application of IN was associated with a shorter duration of hospitalization ( p = .030) and lower white blood cell (WBC) and creatinine (Cr) levels in post-treatment children ( p = .003, p = .010). It was also associated with higher levels of forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEV) after treatment ( p = .014, p = .001, p = .002) and higher levels of immune CD4+/CD8+ ratio after treatment ( p = .001) and reduced symptoms of vomiting among the adverse effects ( p = .047).

This retrospectively study collected 61 patients with intestinal obstruction. The patients were classified into the group of simple or strangulated intestinal obstruction according to operation. The age, sex, basic diseases, lesion sites and inflammatory indicators such as PCT, IL-6, SAA and CRP in two groups were collected and analyzed. The Students’ T-test and the Mann-Whitney U test were used to analyze normally and non-normally distributed data, respectively. The categorical variable was analyzed by the chi-square test. The receiver-operating characteristic (ROC) curve and the area under the curve (AUC) were used to predict the differential diagnostic value of single and combined detection of the above clinical inflammatory indicators. The serum levels of PCT, IL-6, SAA and CRP of the strangulated group were significantly higher than those of the simple group ( p < .05). The areas under the ROC curve (AUC) were 0.907 for PCT, 0.712 for IL-6, 0.723 for SAA and 0.681 for CRP. With the cutoff values of PCT (0.24 ng/L), IL-6 (19.55 pg/L), SAA (282.50 mg/L) and CRP (63.00 mg/L), the sensitivity and specificity were 86.40% and 87.20% for PCT, 68.20% and 76.90% for IL-6, 59.10% and 87.20% for SAA, 63.60% and 87.20% for CRP, respectively. And the sensitivity and specificity were 86.40% and 89.70% for combined model. The differences between PCT and the combined model are tiny and neither clinically nor statistically significant. For discriminating strangulated intestinal obstruction from simple intestinal obstruction, PCT alone may be the preferred approach due to its simplicity.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48045062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have found that the abnormal expression of claudins (CLNDs) can influence the functions of tight junctions (TJs) and plays an important role in the occurrence, development, and metastasis of malignant tumours in a variety of epithelial malignant tumours. However, the roles of the different CLNDs in ccRCC are poorly understood. Methods: Used the GEPIA, UALCAN, HPA, Kaplan-Meier Plotter, cBioPortal, String-DB, GeneMANIA, Metascape, and TIMER databases to collect data. Results: The expression levels of CLDN7, 8, 10, 11, 14, 16, and 19 were significantly reduced and promoters were hypermethylated in ccRCC-affected tissues. ccRCC patients with low expression levels are associated highly with the clinical cancer stages, tumour grades, and poor overall survival. Protein interaction and enrichment analysis showed the differential expressions of CLDNs were primarily associated with epithelial cell differentiation and regulation of cell adhesion. Moreover, differential expressions of CLDNs were significantly correlated with the infiltration of diverse immune cells, including six types of CD4+ T cells, macrophages, neutrophils, B cells, CD8+ T cells, and dendritic cells in ccRCC. Conclusion: They are expected to serve as biomarkers for predicting the prognosis of ccRCC patients.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48121528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 42 patients with IBD (22 UC and 20 CD) followed in the gastroenterology clinic and 42 healthy controls matched for gender and age were enrolled in the study. All participants underwent optical coherence tomography angiography. Macular vessel density, central retinal, and choroidal thicknesses were measured. No significant differences were observed between IBD patients and control subjects as regards superficial vascular plexus density, deep vascular plexus density, and choriocapillaris vascular density, retinal and choroidal thickness in the macular area ( p > .05). Although not statistically significant, vascular density generally increased. On the other hand, retinal and choroidal thickness were decreased. It could be said that there is a reactive increase in retinal vascular density and a decrease in retinal and choroidal thickness as a result of atherosclerotic changes in IBD.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47938828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the effects of PYT in vitro on HCT116 and HT-29 cell lines and to analyse the intricate mechanism of NF-κB-β-catenin signalling pathways. Both cell lines were treated with PYT, and analysed for cell viability, apoptosis, progression of cell cycle, and DNA fragmentation. Gene and protein expression analysis was performed to assess the molecular mechanism. PYT suppressed the proliferation of colorectal cancer cell lines in a dose- and time-dependent manner with an estimated IC50 value of 2.96 and 3.35 mm, respectively. PYT caused cell cycle arrest at the G2/M phase in both CRC cell lines and induced mitochondrial intrinsic apoptosis via activation of caspase-9 and caspase-3 cascade. PYT suppressed the expression of pro-inflammatory markers especially COX-2 and iNOS, and IL-lβ, IL-6, and IL-10. Analysing the mechanism behind the effects of PYT showed that it suppressed the levels of NF-κB and β-catenin and inhibited the levels of cyclin Dl and c-Myc (its downstream targets) and COX-2. The results collectively indicate the potent anti-inflammatory and anti-proliferative effects of PYT in CRC cell lines that were mediated by downregulating the β-catenin and NF-κB signalling pathways. Results advocate that natural supplementation of PYT can be an effective preventive approach in controlling cancer of colorectal region.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42272411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interleukin-33 (IL-33) is related to the occurrence and development of RIF, but the underlying mechanism remains unclear. Here, we investigated whether IL-33 mediates the EMT of RTECs by activating the NF-κB/Twist1 signalling pathway. Methods: In vivo, the RIF animal model induced by unilateral ureteral obstruction (UUO) was established. The effects of exogenous IL-33 and anti-IL-33 antibodies were evaluated. In vitro, the EMT of RTECs was induced by IL-33. The inhibition of the nuclear factor kappa-B (NF-κB) by the pyrrolidine dithiocarbamate (PDTC) and the knockdown of the suppression of tumorigenicity 2 (ST2) by small interference RNA were used to observe whether IL-33 mediates the EMT of RTECs through the NF-κB/Twist1 signaling pathway. Results: In vivo, exogenous IL-33 significantly aggravated UUO-induced pathological damage and collagen deposition, down-regulated E-cadherin expression, and up-regulated α-smooth muscle actin and Vimentin expressions. Moreover, exogenous IL-33 increased the levels of phospho-IκB-α (p-IκB-α) and phospho-NF-κB p65 (p-NF-κB p65), NF-κB p65 nuclear translocation, and Twist1 nuclear expression. However, these effects were reversed by the anti-IL-33 antibody. In vitro , the increases in the levels of p-IκB-α, p-NF-κB p65, NF-κB p65 nuclear translocation, and Twist1 nuclear expression induced by IL-33 were inhibited by the knockdown of PDTC or ST2. IL-33-mediated EMT of RTECs was also significantly reversed. However, NF-κB inhibitor PDTC had no significant effect on ST2 expression. Conclusions: The IL-33/ST2 axis may up-regulate the expression of Twist1 through the NF-κB signalling pathway, thereby inducing the EMT of RTECs and leading to RIF.","PeriodicalId":55162,"journal":{"name":"European Journal of Inflammation","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44109633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
