The human ABF-1 gene is expressed in activated B-cells and Epstein-Barr virus-immortalized lymphoblastoid cell lines. ABF-1 represents the only member belonging to the basic helix-loop-helix (bHLH) family of transcription factors whose expression pattern is restricted to B-cells. ABF-1 forms heterodimeric complexes with E2A to modulate gene transcription.(More)
Low molecular weight heparins are a group of drugs that have only recently been introduced in clinical practice. The are widely used for prophylaxis in thromboembolic disease and are being employed increasingly to treat established venous thrombosis. One way in which these drugs are often used is for prophylaxis in the perioperative period for patients at(More)
Although cellular prion protein PrPC is well known for its implication in Transmissible Spongiform Encephalopathies, its functions remain elusive. Combining in vitro and in vivo approaches, we here show that PrPC displays the intrinsic capacity to protect neuronal cells from a pro-inflammatory TNFα noxious insult. Mechanistically, PrPC coupling to the NADPH(More)
In prion diseases, the brain lesion profile is influenced by the prion "strain" properties, the invasion route to the brain, and still unknown host cell-specific parameters. To gain insight into those endogenous factors, we analyzed the histopathological alterations induced by distinct prion strains in the mouse cerebellum. We show that 22L and ME7 scrapie(More)
