In the present study, HERV-W env-derived epitopes presented by HLA-A~*0201 are described with the potential for use in adoptive immunotherapy. Five peptides displaying HLAA~*0201-binding motifs were predicted using SYFEPITHI and BIMAS, and synthesized. A CCK-8 assay showed peptides W, Q and T promoted lymphocyte proliferation. Stimulation of peripheral blood mononuclear cells from HLA-A~*0201^+ donors with each of these peptides induced peptidespecific CD8^+ T cells. High numbers of IFN-γ-secreting T cells were also detectable after several weekly stimulations with W, Q and T. Besides lysis of HERV-W env-loaded target cells, specific apoptosis was also observed. These data demonstrate that human T cells can be sensitized toward HERV-W env peptides(W, Q and T) and, moreover, pose a high killing potential toward HERV-W env-expressing U251 cells. In conclusion, peptides W Q and T, which are HERV-W env antigenic epitopes, have both antigenicity and immunogenicity, and can cause strong T cell immune responses. Our data strengthen the view that HERV-W env should be considered as an autoantigen that can induce autoimmunity in neuropsychiatric diseases, such as multiple sclerosis and schizophrenia. These data might provide an experimental foundation for a HERV-W env peptide vaccine and new insight into the treatment of neuropsychiatric diseases.展开更多

文摘Stem cells play a crucial role in maintaining tissue regenerative capacity and homeostasis.However,mechanisms associated with stem cell senescence require further investigation.In this study,we conducted a proteomic analysis of human dental pulp stem cells(HDPSCs)obtained from individuals of various ages.Our findings showed that the expression of NUP62 was decreased in aged HDPSCs.We discovered that NUP62 alleviated senescence-associated phenotypes and enhanced differentiation potential both in vitro and in vivo.Conversely,the knocking down of NUP62 expression aggravated the senescence-associated phenotypes and impaired the proliferation and migration capacity of HDPSCs.Through RNA-sequence and decoding the epigenomic landscapes remodeled induced by NUP62 overexpression,we found that NUP62 helps alleviate senescence in HDPSCs by enhancing the nuclear transport of the transcription factor E2F1.This,in turn,stimulates the transcription of the epigenetic enzyme NSD2.Finally,the overexpression of NUP62 influences the H3K36me2 and H3K36me3 modifications of anti-aging genes(HMGA1,HMGA2,and SIRT6).Our results demonstrated that NUP62 regulates the fate of HDPSCs via NSD2-dependent epigenetic reprogramming.

文摘Pulpitis is a common infective oral disease in clinical situations.The regulatory mechanisms of immune defense in pulpitis are still being investigated.Osteomodulin(OMD)is a small leucine-rich proteoglycan family member distributed in bones and teeth.It is a bioactive protein that promotes osteogenesis and suppresses the apoptosis of human dental pulp stem cells(hDPSCs).In this study,the role of OMD in pulpitis and the OMD-induced regulatory mechanism were investigated.The OMD expression in normal and inflamed human pulp tissues was detected via immunofluorescence staining.Intriguingly,the OMD expression decreased in the inflammatory infiltration area of pulpitis specimens.The cellular experiments demonstrated that recombined human OMD could resist the detrimental effects of lipopolysaccharide(LPS)-induced inflammation.A conditional Omd knockout mouse model with pulpal inflammation was established.LPS-induced inflammatory impairment significantly increased in conditional Omd knockout mice,whereas OMD administration exhibited a protective effect against pulpitis.Mechanistically,the transcriptome alterations of OMD overexpression showed significant enrichment in the nuclear factor-κB(NF-κB)signaling pathway.Interleukin-1 receptor 1(IL1R1),a vital membrane receptor activating the NF-κB pathway,was significantly downregulated in OMD-overexpressing hDPSCs.Additionally,the interaction between OMD and IL1R1 was verified using co-immunoprecipitation and molecular docking.In vivo,excessive pulpal inflammation in Omd-deficient mice was rescued using an IL1R antagonist.Overall,OMD played a protective role in the inflammatory response via the IL1R1/NF-κB signaling pathway.OMD may optimize the immunomodulatory functions of hDPSCs and can be used for regenerative endodontics.
文摘BACKGROUND Colorectal cancer is the third most common malignancy and the fourth leading cause of cancer-related deaths worldwide.Several studies have shown an association between gut microbiota and colorectal cancer.Gut microbiota is unique and can be influenced by geographic factors and habits.This study aimed to determine the diversity and composition of colonic mucosal microbiota in patients with and without colorectal cancer.AIM To determine the diversity and composition of colonic mucosal microbiota in patients with and without colorectal cancer in Indonesia.METHODS This case-control study included 59 subjects(35 colorectal cancer patients and 24 non-colorectal cancer patients indicated for colonoscopy at Dr.Cipto Mangunkusumo Gastrointestinal Endoscopy Center and Fatmawati Hospital.Microbiota examination was performed using 16S rRNA sequencing.Bioinformatics analysis was performed using the wf-metagenomics pipeline from EPI2Me-Labs(Oxford Nanopore Technologies platform).RESULTS Patients with colorectal cancer had a higher median index value on the Shannon index(3.28 vs 2.82,P>0.05)and a lower value on the Simpson index(0.050 vs 0.060,P>0.05).Significant differences in beta diversity were observed at the genus(P=0.002)and species levels(P=0.001).Firmicutes,Proteobacteria,Bacteroidetes,and Fusobacteria were the dominant phyla.The genera Bacteroides,Campylobacter,Peptostreptococcus,and Parvimonas were found more frequently in colorectal cancer,while Faecalibacterium,Haemophilus,and Phocaeicola were more frequently found in non-colorectal cancer.The relative abundance of Fusobacterium nucleatum,Bacteroides fragilis,Enterococcus faecalis,Campylobacter hominis,and Enterococcus faecalis species was significantly elevated in patients with colorectal cancer.Meanwhile,Faecalibacterium prausnitzii,Faecalibacterium duncaniae,and Prevotella copri were more commonly found in non-colorectal cancer.CONCLUSION Patients with colorectal cancer exhibit distinct differences in the composition and diversity of their colonic mucosal microbiota compared to those with non-colorectal cancer.This study was reviewed and approved by the Ethics Committee of Faculty of Medicine,Universitas Indonesia(No.KET-1517/UN2.F1/ETIK/PPM.00.02/2023).

文摘AIM:To investigate the etiology of ocular pathogens and to establish the various pathogens present in human immunodeficiency virus(HIV)patients with cytomegalovirus retinitis(CMVR).METHODS:A total of 17 HIV-infected patients with concomitant eye disorders were enrolled.Patients were divided into CMVR group(10 patients,18 eyes)and non-CMVR group(7 patients,9 eyes)based on clinical manifestations and the presence of cytomegalovirus(CMV)-DNA in ocular specimens.The viral load of CMV was assessed using polymerase chain reaction in aqueous humor,vitreous fluid,and peripheral blood samples of patients in the CMVR group.Additionally,peripheral blood CD4^(+)T cell counts were measured in both groups.RESULTS:In the CMVR group,the CMV-DNA load in the vitreous and aqueous humor samples was substantially higher than in the peripheral blood samples(P<0.01).CMVDNA load in the aqueous humor and vitreous samples of the two eyes in the CMVR group was determined to be statistically significant(10 patients,16 eyes,P=0.018,0.012).Peripheral blood CD4^(+)T cell counts in the CMVR group were adversely linked with the CMV-DNA load in both the aqueous humor and peripheral blood(P=0.005,0.048).Compared with the non-CMVR group,the peripheral blood CD4^(+)T cell count in the CMVR group decreased significantly(P=0.014).The peripheral blood CD4^(+)T cell count exceeded 300 cells/μL in 85.71%of non-CMVR patients,whereas it was below 100 cells/μL in 90.00%of the CMVR group.The intraocular specimens of the patients who underwent CMVR testing did not include any additional infections.CONCLUSION:In HIV-associated CMVR patients,there may exist alternative,yet unidentified,infection pathways for intraocular CMV in addition to the conventional route.The substantial difference in CMV-DNA load between the eyes of most CMVR patients suggests that CMV may originate from different sources in each eye.The proportion of peripheral blood CD4^(+)T cells in HIV patients is negatively correlated with the quantity of CMV viruses in their eyes.The peripheral blood count of<100 cells/μL indicates a considerable increase in the risk of concurrent CMVR.Multi-ocular pathogen presentations are uncommon in HIV individuals with CMVR.

文摘Background Breast cancer(BC)incidence and mortality vary significantly across countries,highlighting the need to update the global burden of female BC,including current trends and future projections.Methods Data were sourced from GLOBOCAN 2022,including estimated new cases and deaths from BC across 21 United Nation(UN)regions and 185 countries,the age-standardized incidence rate(ASIR)and mortality rate(ASMR),the estimated annual percentage changes(EAPC),and demographic projections through 2050.The region-specific and country-specific BC burden for women of all ages and for young women(<40 years old)was reorganized and re-plotted to highlight subgroup differences.Linear regression was used to explore the link between ASIR/ASMR and the human development index(HDI).Transitioning countries referred to those with low or medium HDI,while transitioned countries were those with high or very high HDI.Results In 2022,an estimated 2.3 million new BC cases and 666,000 BC-related deaths occurred globally,accounting for 23.8%and 15.4%of all cancer cases and deaths in women,respectively.Regionally,Eastern Asia reported the highest number of cases(480,019,ASIR:37.54/100,000),while South-Central Asia had the highest number of deaths(135,348,ASMR:13.41/100,000).At the country level,China had the highest number of cases due to its large population,whereas India reported the highest number of deaths.ASIR for both overall and early-onset BC increased with HDI,while ASMR for early-onset BC decreased with HDI(P<0.05).Overall BC showed an increasing trend in ASIR during 2003–2015(EAPC:0.92%)and a decreasing trend in ASMR during 2006–2016(EAPC:-1.06%).Early-onset BC showed a more significant rise in ASIR(EAPCs:1.4%)and a slight increase in ASMR(EAPCs:0.16%).If national rates remain stable,BC cases and deaths will increase by 54.7%and 70.9%,respectively,by 2050.Notably,increased early-onset BC cases are only observed in transitioning countries,while decreased cases are seen in transitioned countries.Conclusions Breast cancer remains the leading cancer burden in women,particularly in transitioning countries.Addressing this growing burden requires urgent integration of primary prevention,early detection and high-quality treatment through multi-sectoral collaboration.

文摘This study investigated environmental distribution and human exposure of polycyclic aromatic hydrocarbons(PAHs)and their derivatives in one Chinese petroleum refinery facility.It was found that,following with high concentrations of 16 EPA PAHs(∑Parent-PAHs)in smelting subarea of studied petroleum refinery facility,total derivatives of PAHs[named as XPAHs,including nitro PAHs(NPAHs),chlorinated PAHs(Cl-PAHs),and brominated PAHs(Br-PAHs)]in gas(mean=1.57×10^(4)ng/m^(3)),total suspended particulate(TSP)(mean=4.33×10^(3) ng/m^(3))and soil(mean=4.37×10^(3) ng/g)in this subarea had 1.76-6.19 times higher levels than those from other subareas of this facility,surrounding residential areas and reference areas,indicating that petroleum refining processes would lead apparent derivation of PAHs.Especially,compared with those in residential and reference areas,gas samples in the petrochemical areas had higher∑NPAH/∑PAHs(mean=2.18),but lower∑Cl-PAH/∑PAHs(mean=1.43×10^(-1))and∑Br-PAH/∑PAHs ratios(mean=7.49×10^(-2)),indicating the richer nitrification of PAHs than chlorination during petrochemical process.The occupational exposure to PAHs and XPAHs in this petroleum refinery facility were 24-343 times higher than non-occupational exposure,and the ILCR(1.04×10^(-4))for petrochemical workers was considered to be potential high risk.Furthermore,one expanded high-resolution screening through GC Orbitrap/MS was performed for soils from petrochemical area,and another 35 PAHs were found,including alkyl-PAHs,phenyl-PAHs and other species,indicat-ing that profiles and risks of PAHs analogs in petrochemical areas deserve further expanded investigation.
文摘BACKGROUND This case report describes a protocol developed by Danaun Medical Clinic for the introduction of a pioneering intervention comprising intravenous human placen-tal extract(HPE)therapy to improve the liver function of patients with chronic liver disease(CLD).CASE SUMMARY This study involved data from patients whose chief complaint was reduced quality of life attributable to CLD.The new treatment approach resulted in improvements in the liver function and fatty liver of 30 patients with CLD.Im-provements were observed using abdominal ultrasonography.Unlike traditional methods,this protocol provided more sustainable and meaningful results.Treat-ment with 10 mL of HPE administered intravenously once or twice per week significantly improved liver function.The observed improvements in fatty liver and liver function suggest the utility of this approach for the management of patients with CLD.CONCLUSION This case series highlights the potential of innovative treatments for patients with CLD that could improve the quality of life of the patients.

文摘The Internet of Things(IoT)and mobile technology have significantly transformed healthcare by enabling real-time monitoring and diagnosis of patients.Recognizing Medical-Related Human Activities(MRHA)is pivotal for healthcare systems,particularly for identifying actions critical to patient well-being.However,challenges such as high computational demands,low accuracy,and limited adaptability persist in Human Motion Recognition(HMR).While some studies have integrated HMR with IoT for real-time healthcare applications,limited research has focused on recognizing MRHA as essential for effective patient monitoring.This study proposes a novel HMR method tailored for MRHA detection,leveraging multi-stage deep learning techniques integrated with IoT.The approach employs EfficientNet to extract optimized spatial features from skeleton frame sequences using seven Mobile Inverted Bottleneck Convolutions(MBConv)blocks,followed by Convolutional Long Short Term Memory(ConvLSTM)to capture spatio-temporal patterns.A classification module with global average pooling,a fully connected layer,and a dropout layer generates the final predictions.The model is evaluated on the NTU RGB+D 120 and HMDB51 datasets,focusing on MRHA such as sneezing,falling,walking,sitting,etc.It achieves 94.85%accuracy for cross-subject evaluations and 96.45%for cross-view evaluations on NTU RGB+D 120,along with 89.22%accuracy on HMDB51.Additionally,the system integrates IoT capabilities using a Raspberry Pi and GSM module,delivering real-time alerts via Twilios SMS service to caregivers and patients.This scalable and efficient solution bridges the gap between HMR and IoT,advancing patient monitoring,improving healthcare outcomes,and reducing costs.
