Proliferation, Adult Neuronal Stem Cells and Cells Migration in Pallium during Constitutive Neurogenesis and after Traumatic Injury of Telencephalon of Juvenile Masu Salmon, .

A study of the lateral pallium in zebrafish and the visual tectum of the medaka revealed a population of adult neuroepithelial (NE) cells supported from the early stage of development to various postembryonic stages of ontogenesis. These data emphasize the importance of non-radial glial stem cells in the neurogenesis of adult animals, in particular fish. However, the distribution, cell cycle features, and molecular markers of NE cells and glial progenitors in fish are still poorly understood at the postembryonic stages of ontogenesis.

Dependence of the coupling of dopamine receptors to G proteins on the protein redox state in the neural plasma membranes of pond snail.

Binding analysis using [3H]dopamine has shown that reduction of protein thiol groups with dithiothreitol (DTT) led to a dual effect on the receptors. First, the amount of dopamine-binding sites on the membranes and their affinity to the ligand were decreased. Second, the affinity of the receptors to [3H]dopamine was enhanced in the presence of GDP.
