Project description:We have performed a genome wide transcriptional survey of liver biopsies obtained from patients in Hunan China, who have chronic schistosomiasis with and without past viral hepatitis history, compared to patients with no liver disease history or indicators. These results present a comprehensive transcriptional profile of chronic schistosomiasis japonica patients and demonstrate similarities and differences with other hepatic diseases. These unique features of gene expression, in conjunction with previous reports of the cellular composition of granuloma formation and recovery, present an improved understanding of the molecular immunopathology and general physiological status underlying hepatic schistosomiasis.

Project description:Background: The parasitic trematode Schistosoma mansoni is one of the major causative agents of human schistosomiasis, which afflicts 200 million people worldwide. Praziquantel is still the only drug used for schistosomiasis treatment and reduction in drug efficiency has prompting the search for new therapeutic compounds against this disease. Our group has demonstrated that heme crystallization into hemozoin (Hz) within S. mansoni gut is a major heme detoxification route involving lipid droplets in this process and acting as a potential chemotherapeutical target. In the present work, we investigated the effects of the antimalarial quinine (QN) in a murine schistosomiasis model by using a combination of biochemical, cell biology and molecular biology approaches. Methodology/Principal Findings: Treatment of S. mansoni-infected female Swiss mice with daily intraperitoneal injections of QN (75mg/kg/day) from 11th to 17th day after infection decreased not only total, males and females worm burden (46.2 %-51.0 %), eggs production, but also the granulomatous reaction to parasite eggs trapped in the liver. These effects correlated with a significant impairment of Hz production (40%) specifically in S. mansoni females, being parallel to remarkable ultrastructural changes in female worms, particularly in the gut epithelium. Microarray gene expression analysis indicated that QN treatment increased the expression of transcripts related to musculature, protein synthesis and repair mechanisms. Conclusions: The overall significant reduction in several disease burden parameters by QN treatment indicates that interference of Hz formation in S. mansoni is a valid chemotherapeutical target for development of new antischistosomal drugs.

The gene expression profile of the human liver was examined for chronic patients with Schistosoma japonicum infections. Microarray analysis was performed on cRNA synthesised from total RNA derived from the liver biopsy tissue from huan China. Three groups were examined based on infections status [C] were without history or indicators of schistosomiasis or viral heapatitis controls ; [S] with a history or active for schistosomiasis but no indicators of viral heapatitis; and [S]

Project description:Background: Schistosomiasis is a major public health challenge and one of the neglected tropical diseases globally. Schistosoma haematobium, the causative agent of urogenital schistosomiasis, is primarily endemic in African countries, with school-aged children (7 to 15 years) considered the most vulnerable population. The current diagnostic method relies on identifying parasite eggs in urine through microscopy, which is labor-intensive, requires specialized skills, and is often limited in sensitivity, especially in mild infections. Disease-related biomarkers offer a promising avenue for advancing disease diagnosis and detection. Method: A total of 135 school-aged children (aged 7—15 years) from Zanzibar were recruited for this study. To identify potential host protein biomarkers, data independent acquisition (DIA) proteomics combined with machine learning was used to screen for differentially expressed proteins in the urine samples from individuals infected with schistosome haematobium. Machine learning was used to pinpoint the most discriminative proteins, which were subsequently validated using enzyme-linked immunosorbent assay (ELISA). Results: Proteomic analysis identified 823 common host proteins in urine samples from the infection group, with 269 proteins showing significant differential expression. Of these, 149 were up-regulated and 120 were down-regulated in the infected group. Machine learning further highlighted SYNPO2, CD276, α2M, LCAT, and hnRNPM as the most discriminating biomarkers for Schistosomiasis haematobium infection. ELISA validation confirmed the differential expression trends of these proteins, underscoring their diagnostic potential. Conclusions: This study identified key urinary protein biomarkers associated with Schistosoma haematobium

Project description:In schistosomiasis japonica, the egg-induced granulomatous response and the development of extensive hepatic fibrosis is the main pathology. Information regarding the specific mechanisms associated with granuloma regression and the subsequent recovery events in the host liver are still limited. In this study, a murine model of schistosomiasis japonica was used to characterise the multicellular pathways occurring during liver regeneration. Schistosoma japonicum-infected C57BL/6 mice were administered with the drug praziquantel (PZQ), on a daily basis for five consecutive days to eliminate all adult parasites. The pathological changes of PZQ-treated groups after 3, 6 and 7 weeks post PZQ treatment were examined, along with the assessment of cellular infiltration to the liver. PZQ treatment significantly reduced the degree of splenomegaly, granuloma density and the collagen deposition of liver fibrosis. The infiltration of inflammatory cells, including neutrophils, eosinophils and macrophages to the liver were as well significantly decreased. Transcriptomic analysis revealed the significant up-regulation of fatty acid metabolism genes and the identification of peroxisome proliferator-activated receptor alpha (PPAR-α) as the upstream regulator during the process of liver recovery. Aryl hydrocarbon receptor (AhR) signalling pathway that is involved primarily in the regulation of hepatic enzymes responsible for xenobiotic metabolism was as well differentially up-regulated. These findings indicate that schistosome egg-induced fibrogenesis process is reversible, and provide a better understanding of the regression mechanisms associated with hepatic schistosomiasis. These results hold important implications for the future alleviation of this and other fibrotic diseases of clinical significance. C57BL/6 murine model infected with S. japonicum were treated orally with Praziquantel (PZQ) after 7 weeks post infection to examine the hepatic regression process following drug treatment. These PZQ-treated, non PZQ-treated and uninfected mice were then euthanised at 10, 13, and 14 weeks p.i. Livers were collected from each mice, and subjected to total RNA isolation and gene expression analysis. Microarray analysis of this study was performed using samples derived from 3 individual mice per group/time-point.

Project description:Background: Schistosomiasis is a chronic neglected tropical disease that is characterized by continued inflammatory challenges to the exposed population, and it has been established as a possible risk factor in the aetiology of bladder cancer. Improved diagnosis of schistosomiasis and its associated pathology is possible through mass spectrometry to identify biomarkers among the infected population, which will influence early detection of the disease and its subtle morbidity. Methodology: A high-throughput proteomic approach was used to analyse human urine samples for 49 volunteers from Eggua, a schistosomiasis endemic community in South-West, Nigeria. The individuals were previously screened for Schistosoma haematobium and structural bladder pathologies via microscopy and ultrasonography respectively. Samples were categorised into schistosomiasis, schistosomiasis with bladder pathology, bladder pathology, and a normal healthy control group. These samples were analysed to identify potential protein biomarkers. Results: A total of 1306 proteins and 8752 unique peptides were observed in this study (FDR = 0.01). Fifty-four human proteins were found to be potential biomarkers for schistosomiasis and bladder pathologies due to schistosomiasis by label-free quantitative comparison between groups. Thirty-six (36) parasite-derived potential biomarkers were also identified, which include some existing putative schistosomiasis biomarkers that have been previously reported. Some of these proteins include Elongation factor 1 alpha, phosphopyruvate hydratase, histone H4 and heat shock proteins (HSP 60, HSP 70). Conclusion: These findings provide an in-depth analysis of potential schistosoma and human host protein biomarkers for diagnosis of chronic schistosomiasis caused by Schistosoma haematobium and its pathogenesis.
