Branched-chain amino acids, particularly leucine, are thought to activate nutrient sensing pathways in the hypothalamus that regulate food intake and energy homeostasis. In the light of recent controversial findings of leucine’s effect on energy homeostasis further clarification of the metabolic impact of dietary leucine supplementation is required. We(More)
GSK3β (glycogen synthase kinase 3β) is a ubiquitous kinase that plays a key role in multiple intracellular signalling pathways, and increased GSK3β activity is implicated in disorders ranging from cancer to Alzheimer's disease. In the present study, we provide the first evidence of increased hypothalamic signalling via GSK3β in leptin-deficient Lep(ob/ob)(More)
While the concept of the Neurovascular Unit (NVU) is increasingly recognized for exploring mechanisms of tissue damage in ischemic stroke, immunohistochemical analyses are of interest to specifically visualize constituents like the endothelium. Changes in immunoreactivity have also been discussed to reflect functional aspects, e.g., the integrity of the(More)
BACKGROUND/AIMS It is suggested that during fibrogenesis as well as during carcinogenesis of the liver, the hepatic microvascular phenotype is transformed from sinusoids - which lack a basement membrane--into continuous capillaries which rest on a basement membrane. As transforming growth factor (TGF)-beta1 seems to be the most effective mediator in the(More)
Inflammatory mechanisms were recently identified as contributors to delayed neuronal damage after ischemic stroke. However, therapeutic strategies are still lacking, probably related to the outstanding standardization on inflammatory cell recruitment emerging from predominantly artificial stroke models, and the uncertainty on functional properties of(More)
