[Endogenous opioids].

Tierarztliche Praxis, 1985
The discovery of the opioid receptors and their corresponding ligands, the opioid peptides, is of fundamental importance as regards our understanding of a variety of functional mechanisms in the central and peripheral nervous system. This review considers the distribution of the multiple opioid peptides within the organism as well as their tissue ...

Endogenous opioid peptides in pregnancy

BJOG: An International Journal of Obstetrics & Gynaecology, 1983
Summary. Plasma levels of two endogenous opioid peptides, β‐endorphin and met‐enkephalin, as well as immunoreactive N‐terminal β‐lipotrophin (N‐LPH) were studied in normal pregnant women from 8 to 41 weeks gestation. A total of 116 samples were assayed for β‐endorphin‐like immunoreactivity (C‐LPH), 103 for N‐LPH and 75 for met‐enkephalin.

Endogenous opioids and social behavior

Neuroscience & Biobehavioral Reviews, 1980
Evidence for the hypothesis that brain-opioids mediate social affect and social attachments is summarized. Opiates and opioids are very effective in reducing social separation-induced distress vocalizations (DVs), in puppies, young guinea pigs and chicks, while opiate antagonists can increase DVs.

Endogenous Opioids and HIV Infection

1996
Beta endorphin enhanced the HIV-p24 production in fetal microglia infected with HIV-1 JR-CSF a strain that replicates poorly in these cells. Enhancement of HIV-p24 production by beta endorphin was associated with increased tumor necrosis factor a, interleukin-1 and IL6 production. In addition, beta endorphin activated parent HIV promoter. However, this

Endogenous opioid systems in brain

The American Journal of Medicine, 1980
Despite the extensive use of opiates since ancient times, their molecular mechanisms of action are only now being unravelled. The past six years have seen the unfolding of an endogenous opioid neurotransmitter system whose activation mimics opiate action.

Cholestasis and Endogenous Opioids

Clinical Pharmacokinetics, 2007
A class of endogenous opioids is upregulated in liver disease particular to cholestasis, which contributes to symptoms in liver disease such as pruritus, hypotension and encephalopathy. Symptoms associated with cholestasis are reversed or at least ameliorated by mu opioid receptor antagonists. Palliation of symptoms related to cholestatic liver disease

Multiple endogenous opioid peptides

Trends in Neurosciences, 1983
Abstract All endogenous opioid peptides isolated belong to one of three peptide families, each deriving from a distinct precursor molecule: pro-opiomelanocortin is the common precursor for β-endorphin and ACTH; pro-enkephalin A is the common precursor for Met-enkephalin and Leu-enkephalin, as well as for several opioid peptides such as peptide E, BAM ...
