pep·tide

(pĕp′tīd′)
A chemical compound that is composed of a chain of two or more amino acids and is usually smaller than a protein. Some hormones and antibiotics are peptides.

Specific receptor for the opioid peptide dynorphin: Structure-activity relationships.
Brain has high densities of opioid receptors and opioid peptide.
These opioid peptide-containing vesicles often are found in the same axon terminals with the smaller diameter, small molecule-containing vesicles, and thus many neurons have the capacity to release both small molecule and opioid peptide neurotransmitters (Kandel et al.
Thus, it has been hypothesized that, in response to injury, opioid peptide activity in regional sympathetic ganglia fails to increase, or tolerance develops to locally increased opioid activity, producing a hypersensitive or excessive response to autonomic activity (6, 9).
This is really the first evidence that the brain makes an opioid peptide [of use] to the immune system," he says.
Additional evidence indicates that an alcohol-induced increase of opioid peptide release affects alcohol consumption, and nonselective opioid antagonists that block all opioid receptors, such as naloxone and naltrexone, reliably decrease alcohol intake (Gianoulakis 2004; Oswald and Wand 2004).
Scientific evidence suggests that increased opioid peptide transmission in the basal ganglia might underlie dyskinesia after chronic l-DOPA treatment and that opioid antagonists might be useful as adjuncts to l-DOPA therapy for Parkinson's disease.
The clinical trial report includes data from the four week observation period following one single administration of NP2, delivering Enkephalin, an opioid peptide, specifically to nerves experiencing pain from cancer.
NP2 is a gene transfer vector that expresses the naturally-occurring opioid peptide enkephalin.
