Intravenous immunoglobulin (IVIg) is currently evaluated in clinical trials for the treatment of various disorders of the central nervous system. To assess its capacity to reach central therapeutic targets, the brain bioavailability of IVIg must be determined. We thus quantified the passage of IVIg through the blood-brain barrier (BBB) of C57Bl/6 mice using(More)
Intravenous immunoglobulin (IVIg) is currently in clinical study for Alzheimer’s disease (AD). However, preclinical investigations are required to better understand AD-relevant outcomes of IVIg treatment and develop replacement therapies in case of unsustainable supply. We investigated the effects of IVIg in the 3xTg-AD mouse model, which reproduces both Aβ(More)
Neuropeptide Y (NPY) mediates feeding behavior through a local hypothalamic network formed by the arcuate and paraventricular nuclei (the AP axis). In the hypothalamus, NPY is mainly synthesized in neurons of the arcuate nucleus. These neurons project to the paraventricular nucleus, the site where NPY has the strongest stimulatory effects on food intake of(More)
Intravenous immunoglobulin (IVIg) is a blood-derived product, used for the treatment of immunodeficiency and autoimmune diseases. Since a range of immunotherapies have recently been proposed as a therapeutic strategy for Parkinson’s disease (PD), we investigated the effects of an IVIg treatment in a neurotoxin-induced animal model of PD. Mice received four(More)
Intravenous immunoglobulin (IVIg) is a therapeutic preparation of plasma-derived human IgG and is increasingly used for the treatment of several neurological inflammatory disorders. However, it is not clear whether the IgG molecules contained in IVIg can actually cross the BBB in treated patients. We recently showed that LRP1, an endocytic receptor involved(More)
Human mesenchymal stromal cells (MSC) have been shown to dampen immune response and promote tissue repair, but the underlying mechanisms are still under investigation. Herein, we demonstrate that umbilical cord-derived MSC (UC-MSC) alter the phenotype and function of monocyte-derived dendritic cells (DC) through lactate-mediated metabolic reprogramming.(More)
Hyperphagia in the obese Zucker rat is characterized by the early modification of the dark/light (D/L) rhythm of food intake. This rhythm is mainly driven by the suprachiasmatic nucleus (SCN) and, more controversially, by the ventromedian nucleus (VMN). In the SCN of adult obese Zucker rat, the concentrations of neuropeptide Y (NPY), a potent stimulator of(More)
This study was designed to monitor the developmental changes in insulinemia and lipogenic enzyme activities in both inguinal adipose tissue and liver during suckling (7, 9, 14, and 17 days of age) and weaning (22 and 30 days of age) on to either a low-fat or a high-fat diet in lean (Fa/fa) and obese (fa/fa) rats. Tissues were removed through surgery and(More)
