Schistosomiasis affects over 250 million people worldwide, with the highest prevalence at the age of 10–14 years. The influence of the host’s age on the severity of liver damage is unclear. We infected male 8, 14, and 20-week-old mice with S. mansoni. Hepatic damage, inflammation, fibrosis, and metabolism were analyzed by RT-qPCR, Western blotting,...

Schistosomiasis, a parasitic disease caused by Schistosoma spp., affects more than 250 million people worldwide. S. mansoni in particular affects the gastrointestinal tract and, through its eggs, induces a Th2 immune response leading to granuloma formation. The relationship between egg load and immune response is poorly understood. We investigated...

Schistosomiasis, a widespread neglected tropical disease, presents a complex and multifaceted clinical-pathological profile. Using hamsters as final hosts, we dissected molecular events following Schistosoma mansoni infection in the liver - the organ most severely affected in schistosomiasis patients. Employing TMT-based proteomics, we studied alte...

Schistosomiasis is a parasitic disease affecting more than 250 million people worldwide. The transcription factor c-Jun, which is induced in S. mansoni infection-associated liver disease, can promote hepatocyte survival but can also trigger hepatocellular carcinogenesis. We aimed to analyze the hepatic role of c-Jun following S. mansoni infection....

Background & aims: Schistosomiasis is one of the most prominent parasite-induced infectious diseases affecting more than 250 million people. S. mansoni causes metabolic exhaustion and a strong redox imbalance in the liver causing parenchymal damage and may predispose for cancer. We investigated, whether oxidative stress provokes hepatocellular pro...

Background & Aims Schistosomiasis, is a parasitic infection, which globally affects more than 200 million people. Schistosome eggs, but not the adult worms, are mainly responsible for schistosomiasis-specific morbidity in the liver. It is unclear if S. mansoni eggs consume host metabolites, and how this compromises the host parenchyma. Methods Met...

Schistosomiasis is one of the most prominent parasite-induced infectious diseases, causing tremendous medical and socioeconomic problems. Current studies have reported on the spread of endemic regions and the fear of development of resistance against praziquantel, the only effective drug available. Among the Schistosoma species, only S. haematobium...

Schistosomiasis (bilharzia) is a neglected tropical disease caused by parasitic flatworms of the genus Schistosoma, with considerable morbidity in parts of the Middle East, South America, Southeast Asia, in sub-Saharan Africa, and particularly also in Europe. The WHO describes an increasing global health burden with more than 290 million people thr...

This review covers basic aspects of histone modification and the role of posttranslational histone modifications in the development of allergic diseases, including the immune mechanisms underlying this development. Together with DNA methylation, histone modifications (including histone acetylation, methylation, phosphorylation, ubiquitination, etc....

Wnt proteins are important for developmental processes and certain diseases. WNT5A is a non-canonical Wnt protein that previously has been shown to play a role in the progression of malignant melanoma. High expression of WNT5A in melanoma tumors correlates to formation of distant metastasis and poor prognosis. This has partly been described by the...

Excessive and permanent cytokine production in response to bacterial LPS causes cell and tissue damage, and hence organ failure during sepsis. We have previously demonstrated that zinc treatment prevents LPS-induced TNF-alpha expression and production in human monocytes by inhibiting cyclic nucleotide phosphodiesterase (PDE) activity and expression...

Alpha2HS-glycoprotein/fetuin-A (Ahsg) is a serum protein preventing soft tissue calcification. In trauma and inflammation, Ahsg is down-regulated and therefore considered a negative acute phase protein. Enhancement of Ahsg expression as a protective serum protein is desirable in several diseases including tissue remodelling after trauma and infecti...

The trace element zinc affects several aspects of immune function, such as the release of proinflammatory cytokines from monocytes. We investigated the role of cyclic nucleotide signaling in zinc inhibition of LPS-induced TNF-alpha and IL-1beta release from primary human monocytes and the monocytic cell line Mono Mac1. Zinc reversibly inhibited enz...

Zink ist ein essentielles Spurenelement für das Immunsystem. Die Stimulation von Monozyten mit Lipopolysaccharid (LPS), einem Bestandteil der bakteriellen gramnegativen Zellwand, aktiviert Signalkaskaden, die zur Produktion und Sekretion von proinflammatorischen Zytokinen wie TNF-alpha und IL-1beta führen. Mit Zinkkonzentrationen, die einen inhibit...
