Human neurons express the innate immune response receptor, Toll-like receptor 3 (TLR3). TLR3 levels are increased in pathological conditions such as brain virus infection. Here, we further investigated the production, cellular localisation, and function of neuronal TLR3 during neuronotropic rabies virus (RABV) infection in human neuronal cells. Following(More)
The capacity of a rabies virus to promote neuronal survival (a signature of virulence) or death (a marker of attenuation) depends on the cellular partners recruited by the PDZ-binding site (PDZ-BS) of its envelope glycoprotein (G). Neuronal survival requires the selective association of the PDZ-BS of G with the PDZ domains of two closely related(More)
PURPOSE Lipid peroxidation is an autocatalytic mechanism leading to oxidative destruction of cellular membranes. In renal transplantation, this mechanism is triggered by ischemia/reperfusion and may be of relevance in graft failure. MATERIALS AND METHODS Using specific antibodies directed against malondialdehyde (MDA) and 4-hydroxynonenal (HNE) adducts,(More)
Tissues maintain O2 consumption (VO2) when blood flow and O2 delivery (DO2) are decreased by better matching of blood flow to meet local cellular O2 demand, a process that increases extraction of available O2. This study tested the hypothesis that ATP-sensitive K+ channels play a significant role in the response of pig hindlimb to ischemia. We pump perfused(More)
Cancer cachexia contributes to poor prognosis through progressive depletion of the body's energy and protein reserves; research is revealing the impact of the quantitly of these reserves on survival. Our group has exploitated computed tomography (CT) images to study body composition in cancer patients. We argue that CT taken for the purposes of diagnosis(More)
OBJECTIVE Multiwavelength near infrared (NIR) spectrophotometry can monitor the redox state of cytochrome a,a3 (cyt a,a3) in vivo. Because cyt a,a3 is the most immediate reductant of oxygen, this technique has been proposed to evaluate tissue oxygenation. The purpose of this study was to examine the relationship between cyt a,a3 oxidation level as an(More)
