Strategies to enhance neural stem/precursor cell (NPC) capacity to yield multipotential, proliferative, and migrating pools of cells that can efficiently differentiate into neurons could be crucial for structural repair after neurodegenerative damage. Here, we have generated a lentiviral vector for expression of insulin-like growth factor-I (IGF-1) and(More)
Neural stem cells remain in two areas of the adult mammalian brain, the subventricular zone (SVZ) and the dentate gyrus of the hippocampus. Ongoing neurogenesis via the SVZ-rostral migratory stream pathway maintains neuronal replacement in the olfactory bulb (OB) throughout life. The mechanisms determining how neurogenesis is restricted to only a few(More)
For biotechnological applications, insect cell lines are primarily known as hosts for the baculovirus expression system that is capable to direct synthesis of high levels of recombinant proteins through use of powerful viral promoters. Here, we demonstrate the implementation of two alternative approaches based on the baculovirus system for production of a(More)
It remains unclear how opioid receptors (δ, μ, κ) are implicated in mechanisms controlling differentiation, cell proliferation, and survival. Opioid receptors are coupled to Gi/Go proteins and recent findings have shown that opioid receptors can form a multicomponent signaling complex, consisting of members of G protein and the signal transducer and(More)
The BM89 antigen, first identified in porcine brain by means of a monoclonal antibody, is a neuron-specific molecule widely distributed in the mammalian central and peripheral nervous system (Merkouri and Matsas: Neuroscience 50:53-68, 1992). Here we describe the purification of BM89 antigen from porcine and mouse brain by immunoaffinity chromatography(More)
BM88/Cend1 is a neuronal-lineage specific modulator with a pivotal role in coordination of cell cycle exit and differentiation of neuronal precursors. In the current study we identified the signal transduction scaffolding protein Ran-binding protein M (RanBPM) as a BM88/Cend1 binding partner and showed that BM88/Cend1, RanBPM and the dual specificity(More)
The Regulator of G protein Signalling 4 (RGS4) is a multitask protein that interacts with and negatively modulates opioid receptor signalling. Previously, we showed that the δ-opioid receptor (δ-OR) forms a multiprotein signalling complex consisting of Gi/Go proteins and the Signal Transducer and Activator of Transcription 5B (STAT5B) that leads to neuronal(More)
Research Focus Cellular and Molecular Neurobiology-Gene therapy 1.Identification of protein-protein interactions of the neurogenetic molecule Cend1/BM88. 2.Generation of recombinant adenoviruses, retroviruses and lentiviruses that drive the expression of gene(s) with therapeutic properties in order to analyze their neurogenetic potential and use them to(More)
