Extracellular GABA assisting in organizing dynamic cell assemblies to shorten reaction time to sensory stimulation.

Until recently, glia, which exceeds the number of neurons, was considered to only have supportive roles in the central nervous system, providing homeostatic controls and metabolic supports. However, recent studies suggest that glia interacts with neurons and plays active roles in information processing within neuronal circuits. To elucidate how glia contributes to neuronal information processing, we simulated a sensory neuron-glia (neuron-astrocyte) network model.

Detection of Cholera Toxin by an Immunochromatographic Test Strip.

As cholera toxin (CT) is responsible for most of the symptoms induced by Vibrio cholerae O1 or O139 infection, detection of CT is an important biomarker for diagnosis of the disease. The procedure for pathogenicity analysis of V. cholerae isolates must be carefully developed for the reason that the amount of CT produced by V.

Development of an immunochromatographic test strip for detection of cholera toxin.

Because cholera toxin (CT) is responsible for most of the symptoms induced by Vibrio cholerae infection, detection of CT is critical for diagnosis of the disease. In this study, we constructed an immunochromatographic test strip for detection of CT (CT-IC) with polyclonal antibodies developed against purified recombinant whole CT protein. The detection limit of the CT-IC was 10 ng/mL of purified recombinant CT, and it could detect the CT in culture supernatant of all 15 toxigenic V.
