  2. History of catecholamine research - Wikipedia

    en.wikipedia.org/wiki/History_of_catecholamine...

    In a review of earlier work on catecholamine biosynthesis, German-British biochemist Hermann Blaschko (1900–1993) wrote: "Our modern knowledge of the biosynthetic pathway for the catecholamines begins in 1939, with the publication of a paper by Peter Holtz and his colleagues: they described the presence in the guinea-pig kidneys of an enzyme ...

  3. Catecholamine - Wikipedia

    en.wikipedia.org/wiki/Catecholamine

    Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the ventral tegmental area and the substantia nigra, the latter of which contains neuromelanin ...

  4. L-DOPA - Wikipedia

    en.wikipedia.org/wiki/L-DOPA

    l-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. Furthermore, l-DOPA itself mediates neurotrophic factor release by the brain and CNS.

  6. Dopamine - Wikipedia

    en.wikipedia.org/wiki/Dopamine

    A dopamine molecule consists of a catechol structure (a benzene ring with two hydroxyl side groups) with one amine group attached via an ethyl chain. [14] As such, dopamine is the simplest possible catecholamine, a family that also includes the neurotransmitters norepinephrine and epinephrine. [15]

  7. Adrenaline - Wikipedia

    en.wikipedia.org/wiki/Adrenaline

    Unlike many other hormones, adrenaline (as with other catecholamines) does not exert negative feedback to down-regulate its own synthesis. Abnormal adrenaline levels can occur in various conditions, such as surreptitious adrenaline administration, pheochromocytoma, and other tumors of the sympathetic ganglia.

  8. Adrenergic receptor - Wikipedia

    en.wikipedia.org/wiki/Adrenergic_receptor

    The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...

  9. Dopaminergic cell groups - Wikipedia

    en.wikipedia.org/wiki/Dopaminergic_cell_groups

    Dopaminergic cell groups, DA cell groups, or dopaminergic nuclei are collections of neurons in the central nervous system that synthesize the neurotransmitter dopamine. [1] In the 1960s, dopaminergic neurons or dopamine neurons were first identified and named by Annica Dahlström and Kjell Fuxe, who used histochemical fluorescence. [2]
