The large contribution of intraneuronal deamination to catecholamine turnover, and dependence of this on the vesicular-axoplasmic monoamine exchange process, helps explain how synthesis, release, metabolism, turnovers, and stores of catechlamines are regulated in a coordinated fashion during stress and in disease states.

The monograph tells us that EP is the principle hormone which regulates erythropoiesis, and how it acts by causing a committed but undifferentiated cell to differentiate into an erythroblast, and may also have a role in causing maturation of ERYthroblasts.

The N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-treated monkey provides a model that can be used to examine mechanisms and explore therapies of parkinsonism and the pathological and biochemical changes produced by NMPTP are similar to the well-established changes in patients with parkinsonistan.

Dopamine Biosynthesis Is Selectively Abolished in Substantia Nigra/Ventral Tegmental Area but Not in Hypothalamic Neurons in Mice with Targeted Disruption of the Nurr1 Gene

Dopamine was absent in the substantia nigra and ventral tegmental area of Nurr1-null mice, consistent with absent tyrosine hydroxylase (TH), L-aromatic amino acid decarboxylase, and other DA neuron markers, providing evidence for a new mechanism of DA depletion in vivo and suggesting a unique role for Nurr 1 in fetal development and/or postnatal survival.

Exposure of animals to immobilization (IMMO) markedly and rapidly increases rates of synthesis, release, and metabolism of norepinephrine in all the brain areas mentioned above and supports previous suggestions that in the PVN NE stimulates release of corticotropin-releasing hormone (CRH).
