Allogeneic Stem Cell Transplantation for Acquired Aplastic Anemia: Better Outcome with Bone Marrow as Compared to Peripheral Blood in HLA-Matched Sib…

2009

Abstract Abstract 876 Background: Transplantation of bone marrow (BM) from a HLA-matched sibling donor is an effective treatment for severe aplastic anemia (AA) with long-term survival in excess of 80%. In the recent years there were two trends in allogeneic stem cell transplantation (SCT) for AA: (1) increasing proportion of transplants performed from matched unrelated donors (MUD) and (2) increasing proportion of transplants using peripheral blood progenitor cells (PBSC) as stem cell source instead of BM. A similar switch to PBSC over BM grafts is reported in leukemia transplants. PBSC grafts for leukemia are associated with higher rates of chronic graft-versus-host disease (cGVHD). This …

The endocannabinoid system controls key epileptogenic circuits in the hippocampus.

2006

SummaryBalanced control of neuronal activity is central in maintaining function and viability of neuronal circuits. The endocannabinoid system tightly controls neuronal excitability. Here, we show that endocannabinoids directly target hippocampal glutamatergic neurons to provide protection against acute epileptiform seizures in mice. Functional CB1 cannabinoid receptors are present on glutamatergic terminals of the hippocampal formation, colocalizing with vesicular glutamate transporter 1 (VGluT1). Conditional deletion of the CB1 gene either in cortical glutamatergic neurons or in forebrain GABAergic neurons, as well as virally induced deletion of the CB1 gene in the hippocampus, demonstrat…

CB1 Cannabinoid Receptors and On-Demand Defense Against Excitotoxicity

2003

Abnormally high spiking activity can damage neurons. Signaling systems to protect neurons from the consequences of abnormal discharge activity have been postulated. We generated conditional mutant mice that lack expression of the cannabinoid receptor type 1 in principal forebrain neurons but not in adjacent inhibitory interneurons. In mutant mice,the excitotoxin kainic acid (KA) induced excessive seizures in vivo. The threshold to KA-induced neuronal excitation in vitro was severely reduced in hippocampal pyramidal neurons of mutants. KA administration rapidly raised hippocampal levels of anandamide and induced protective mechanisms in wild-type principal hippocampal neurons. These protecti…
