Drugs that bind to and activate dopamine receptors.
One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

  • Surgical therapy, which is performed at a small number of hospitals, may involve transplantation of dopamine-secreting cells (fetal brain tissue, nerve cells from other parts of the patient's body) into affected areas of the brain or insertion of electrical brain stimulators into the subthalamic nucleus, globus pallidus internus, or ventral intermediate nucleus. (thefreedictionary.com)
  • reduced dopamine levels mean that part of the brain cannot function normally, causing movements to become slow and abnormal. (southerncross.co.nz)
  • Wellbutrin ( bupropion ) interferes with reuptake of dopamine & norepinephrine ( noradrenaline )in the central nervous system , thereby leaving these neurotransmitters to sit longer&stronger in the synapse between communicating brain cells, which enhances dopamine&adrenaline activity at the cellular level. (healthtap.com)
