The plasma membrane of epithelial cells is subdivided into two physically separated compartments known as the apical and basolateral membranes. To obtain directional transepithelial solute transport, membrane transporters (i.e., ion channels, cotransporters, exchangers, and ion pumps) need to be targeted selectively to either of these membrane domains. In(More)
A primary cell culture was developed for efferent dorsal unpaired median (DUM) neurons of the locust. The isolated somata were able to generate Tetrodotoxin (TTX)-sensitive action potentials in vitro. The alpha-like scorpion toxin BmK M1, from the Asian scorpion Buthus martensi Karsch, prolonged the duration of the action potential up to 50 times. To(More)
Microglia are the immune cells of the central nervous system. They are suspected to play important roles in adult synaptogenesis and in the development of the neuronal network. Microglial cells originate from progenitors in the yolk sac. Although it was suggested that they invade the cortex at early developmental stages in the embryo, their invasion pattern(More)
The inhibitory neurotransmitter glycine is known to enhance microglial nitric oxide production. However, up to now, the mechanism is undocumented. Since calcium is an important second messenger in both immune and glial cells, we studied the effects of glycine on intracellular calcium signaling. We found that millimolar concentrations of glycine enhance(More)
BmBKTx1 is a novel short chain toxin purified from the venom of the Asian scorpion Buthus martensi Karsch. It is composed of 31 residues and is structurally related to SK toxins. However, when tested on the cloned rat SK2 channel, it only partially inhibited rSK2 currents, even at a concentration of 1 microm. To screen for other possible targets, BmBKTx1(More)
PURPOSE   Febrile seizures (FS), the most frequent seizure type during childhood, have been linked to temporal lobe epilepsy (TLE) in adulthood. Yet, underlying mechanisms are still largely unknown. Altered γ-aminobutyric acid (GABA)ergic neurotransmission in the dentate gyrus (DG) circuit has been hypothesized to be involved. This study aims at analyzing(More)
Febrile seizures (FS) are the most common type of seizures in childhood and are suggested to play a role in the development of temporal lobe epilepsy (TLE). Animal studies demonstrated that experimental FS induce a long-lasting change in hippocampal excitability, resulting in enhanced seizure susceptibility. Hippocampal neurogenesis and altered ion channel(More)
Cell-based therapies are emerging as an alternative treatment option to promote functional recovery in patients suffering from neurological disorders, which are the major cause of death and permanent disability. The present study aimed to differentiate human dental pulp stem cells (hDPSCs) toward functionally active neuronal cells in vitro. hDPSCs were(More)
Glycine is an inhibitory neurotransmitter acting mainly in the caudal part of the central nervous system. Besides this neurotransmitter function, glycine has cytoprotective and modulatory effects in different non-neuronal cell types. Modulatory effects were mainly described in immune cells, endothelial cells and macroglial cells, where glycine modulates(More)
A more detailed insight into disease mechanisms of multiple sclerosis (MS) is crucial for the development of new and more effective therapies. MS is a chronic inflammatory autoimmune disease of the central nervous system. The aim of this study is to identify novel disease associated proteins involved in the development of inflammatory brain lesions, to help(More)
