    Area of Science:

    • Neuroscience
    • Enzymology
    • Molecular Biology

    Background:

    • Mammalian brain glutamate decarboxylase (GAD) has been extensively studied.
    • Uncertainties persist regarding GAD's molecular weight, forms, and subunit structure.
    • Antibodies to GAD have enabled immunocytochemical studies of GABA-ergic neurons.

    Purpose of the Study:

    • To elucidate the molecular characteristics of mammalian brain GAD.
    • To investigate the organization of central nervous system (CNS) GABA-ergic neurons.
    • To explore the regulatory biochemistry and cellular mechanisms controlling GAD activity.

    Main Methods:

    • Enzyme purification and characterization.
    • Immunocytochemical studies using GAD-specific antibodies.
    • Biochemical analyses of GAD regulation.

    Main Results:

    • Progress in GAD purification and characterization.
    • Immunocytochemistry revealed GABA-ergic neuron organization in CNS regions like the cerebellum and nigrostriatal pathway.
    • Initial studies on cellular regulation of GAD have commenced.

    Conclusions:

    • Understanding GAD enzymology and GABA-ergic neuron distribution facilitates study of GAD's cellular regulation.
    • Cellular regulation of GAD is key to understanding GABA-ergic neuron function.
    • Further research into GAD's molecular properties and regulatory mechanisms is warranted.
