Semaphorin 3A (Sema3A) increased significantly in mouse brain following cerebral ischemia. However, the role of Sema3A in stroke brain remains unknown. Our aim was to determine wether Sema3A functions as a vascular permeability factor and contributes to ischemic brain damage. Recombinant Sema3A injected intradermally to mouse skin, or stereotactically into(More)
Increased brain infiltration of polymorphonuclear neutrophils (PMNs) occurs early after stroke and is important in eliciting brain inflammatory response during stroke recovery. In order to understand the molecular mechanism of PMN entry, we investigated the expression and requirement for Slit1, a chemorepulsive guidance cue, and its cognate receptor, Robo1,(More)
It is well known that the ventral tegmental area (VTA) is a brain region in which virtually all abused drugs exert rewarding effects by activating its dopamine neurons. We recently found that the tumour suppressor enzyme phosphatase and tensin homologue deleted on chromosome 10 (PTEN) directly interacts to a region in the third intracellular loop (3L4F) of(More)
We recently found that the interfering peptide Tat-3L4F is able not only to disrupt the protein-protein interaction of PTEN (phosphatase and tensin homologue deleted on chromosome 10) with the serotonin 5-HT2C receptor in the rat ventral tegmental area (VTA) but also to suppress the conditioned place preference induced by cannabinoid and nicotine without(More)
