Dopamine 2 receptor function
NERVOUS SYSTEM OUTLINE - Quia
2. Specific dopamine receptor blocker. Haloperidol = nonspecific D2 blocker. Block mesolimbic system. Side affects = block dorsal striatum. 3. Modulatory biogenic amine neurotransmitters. Wide host of functionally disparate targets. Each amine neuron has over a million synapses. Less variability in firing rates. Regulate signal-to-noise ratio. 4.

1. Traditional: block dopamine receptors. 2. Atypical: block serotonin receptors (has less extrapyramidal effects) MOA: 1. Dopamine receptor blocking activity in brain. D1, D5. activate adenylyl cyclase. D2, D3, D4. inhibit adenylyl cyclase (D2. correlates to efficacy of neuroleptic) 2. Serotonin receptor blocking activity in brain. S2

The important receptor systems and their ligands are listed in Table 2. There are four types of ligand that act by binding to a cell surface receptor, agonists, antagonists, partial agonists, and inverse agonists (Figure 1). (a) Agonists. Ligand s that bind to a receptor and produce an …

The fact that many drugs used for psychosis are 5-HT 2A [as well as dopamine D2] receptor antagonists, coupled with the fact that agonists at the 5-HT 2A. receptor e.g. LSD] are psychotomimetic has led many to wonder if antagonism of this receptor could in itself be therapeutic in psychosis.
Introduction
The dopamine receptor 2 (D2R) knockout mouse represents a useful model to study the participation of the D2R on growth and GHRH-GH regulation. These knockout mice have hyperprolactinemia and...

These studies demonstrate that PCP, an antagonist on the NMDA, glutamate receptor can induce schizophrenic-like symptoms. This is important because it shows that PCP (a drug which decreases glutamate levels) has very similar effects to drugs such as amphetamine which increase dopamine levels, suggesting that schizophrenia may be linked to ...

Excess dopamine receptor activity is linked to schizophrenia. Too little dopamine in brain can lead to Parkinson’s disease (tremors & decreased mobility). Affects mood, hunger, sleep, and arousal
