Double labelling immunohistochemical characterization of autonomic sympathetic neurons innervating the sow retractor clitoridis muscle [PDF]
, 2008 Retrograde neuronal tracing and immunohistochemical methods were used to define the neurochemical content of sympathetic neurons projecting to the sow retractor clitoridis muscle (RCM). Differently from the other smooth muscles of genital organs, the RCM

Journal of Neuroscience, 1995 The effects of enkephalins selective for delta and mu opioid receptors on inhibitory postsynaptic currents (IPSCs) mediated by GABA were studied in chloride-loaded CA1 pyramidal neurons in adult rat hippocampal slices.

Frontiers in Veterinary Science, 2022 Neuropeptides are secretory peptides characterized by small chains of amino acids linked by peptide bonds. They are majorly found in some mammalian neurons and glial cells, where they modulate a variety of physiological homeostasis.

Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]
, 2004 Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes [PDF]
, 2017 Venom systems have evolved on multiple occasions across the animal kingdom, and they can act as key adaptations to protect animals from predators. Consequently, venomous animals serve as models for a rich source of mimicry types, as non-venomous ...

Endogenous opioid systems alterations in pain and opioid use disorder
Frontiers in Systems Neuroscience, 2022 Decades of research advances have established a central role for endogenous opioid systems in regulating reward processing, mood, motivation, learning and memory, gastrointestinal function, and pain relief.

Enkephalins, catecholamines, and psychological mood alterations: effects of prolonged exercise.
Medicine & Science in Sports & Exercise, 1987 Seven healthy trained men were studied to determine if running at various relative intensities [percent maximal oxygen consumption (VO2max)] alters peripheral venous levels of leucine enkephalin-like material.

Challenges and new opportunities for detecting endogenous opioid peptides in reward
Addiction Neuroscience, 2022 The endogenous opioid peptide system, comprised of enkephalins, endorphins, dynorphins, and nociceptin, is a highly complex neurobiological system. Opioid peptides are derived from four precursor molecules and undergo several processing events yielding ...

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies
Frontiers in Pharmacology, 2015 The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes

The distribution and functions of the enkephalins. [PDF]
Journal of Histochemistry & Cytochemistry, 1980 The enkephalins are two pentapeptides with pharmacological properties similar to narcotic drugs. These peptides are widely distributed in the central nervous system. The basal ganglia contain particularly high concentrations of enkaphalins. In the caudate nucleus ultrastructural studies show that enkephalin is contained within synaptic vesicles ...
