UNLABELLED Lentiviral vectors are attractive tools for liver-directed gene therapy because of their capacity for stable gene expression and the lack of preexisting immunity in most human subjects. However, the use of integrating vectors may raise some concerns about the potential risk of insertional mutagenesis. Here we investigated liver gene transfer by(More)
A major complication of factor replacement therapy for haemophilia is the development of anti-factor neutralizing antibodies (inhibitors). Here we show that liver gene therapy by lentiviral vectors (LVs) expressing factor IX (FIX) strongly reduces pre-existing anti-FIX antibodies and eradicates FIX inhibitors in haemophilia B mice. Concomitantly, plasma FIX(More)
BACKGROUND Diabetics have high prevalence of subclinical coronary artery disease (CAD) with typical characteristics (diffuse disease, large calcifications). Although 64-slice multidetector computed tomography (MDCT) coronary angiography has high diagnostic accuracy to detect CAD, its diagnostic performance in diabetics with suspected CAD is unknown. To(More)
The success of in vivo gene therapy greatly depends on the ability to control the immune response toward the therapeutic transgene. Over the last decade several vector-based and pharmacological approaches have been explored to control the immune-mediated clearance of transgene-expressing cells after viral delivery. One important outcome from these studies(More)
OBJECTIVE To assess the prognostic role of multidetector computed tomography coronary angiography (MDCT-CA) in patients with diabetes with suspected coronary artery disease (CAD). Use of MDCT-CA is increasing in patients with suspected CAD. However, data supporting its prognostic value in patients with diabetes are limited. RESEARCH DESIGN AND METHODS(More)
Dendritic cells (DCs) represent the key regulator of the immune system. The particular milieu in which DCs encounter the antigen together with their intrinsic properties defines their ability to promote an active or a tolerogenic immune response. The development of protocols to differentiate in vitro immunogenic or tolerogenic DCs opened the possibility to(More)
A 60-year-old man with history of hypertension and unspecified left ventricular dysfunction had chest pain at home at 9 am. At 1 pm he was transported to a peripheal hospital and treated for acute myocardial infarction. At 4.30 pm, despite pharmacological and intra aortic balloon pump support , the extreme hemodynamic instability and the echocardiographic(More)
