Natural pseurotins and analogs thereof inhibit activation of B-cells and differentiation into the plasma cells
Conclusion: Our results advance the current mechanistic understanding of the pseurotin-induced inhibition of IgE production in B-cells by linking the effect to STAT signaling, and associated modulation of B-cell proliferation and differentiation. Together with our finding that structurally simpler pseurotin analogs were able to reproduce the effects of natural pseurotins, the presented work has implications for the future research on these secondary metabolites in the context of allergic diseases.Graphical abstact

Abstract Poly(D,L-lactide-co-glycolic) acid (PLGA) is a synthetic copolymer that has been used to design micro/nanoparticles as a carrier for macromolecules, such as protein and nucleic acids, that can be internalized by the endocytosis pathway. However, it is difficult to control the intracellular delivery to target organelles. Here we report an intracellular delivery system of nanoparticles modified with bacterial cytotoxins to the endoplasmic reticulum (ER) and anti-inflammatory activity of the nanoparticles. Subtilase cytotoxin (SubAB) is a bacterial toxin in certain enterohemorrhagic Escherichia coli (EHEC) s...

imarães S Abstract Giardia duodenalis is one of the most important and widespread gastrointestinal parasites in the world. Despite its relevance as a causative agent of diarrhea, asymptomatic giardiasis occurs frequently, especially in low resources settings in which children are exposed to many risk factors. Based on microscopic examination and the polymerase chain reaction (PCR) amplification and sequencing of beta-giardin (bg), triose phosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes, we assessed G. duodenalis occurrence and genetic diversity in isolates of children attending a daycare ce...

AbstractAcute pancreatitis (AP) is termed as idiopathic (IAP) when the underlying conditions of pancreatic inflammation remain unknown. The aim of this study was to identify different clinical features in patients with IAP and AP of known aetiology. All patients hospitalized in our Gastroenterology Unit with an initial diagnosis of AP were recruited. AP was classified as of known aetiology or idiopathic according to clinical examination, serum biochemistry testing, and radiological imaging investigations, and clinical data in both patient groups were compared. A total of 127 patients (80 males, mean age: 57 years) we...
