Enkephalin-like immunoreactivity in Drosophila melanogaster. 1983

M Pagés, and F Jiménez, and A Ferrús, and E Peralta, and G Ramírez, and E Gelpí

Enkephalin-immunoreactive neurons have been identified in the central nervous system of the fruit fly Drosophila melanogaster by immunocytochemical techniques. Analyses of fly extracts by high performance liquid chromatography and radioimmunoassay show a relatively complex pattern of immunoreactive compounds. The most prominent among them has chromatographic properties similar to those of met-enkephalin from which can, however, be distinguished by high-resolution chromatographic techniques.

UI MeSH Term Description Entries
D009420 Nervous System The entire nerve apparatus, composed of a central part, the brain and spinal cord, and a peripheral part, the cranial and spinal nerves, autonomic ganglia, and plexuses. (Stedman, 26th ed) Nervous Systems,System, Nervous,Systems, Nervous
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D001923 Brain Chemistry Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states. Chemistry, Brain,Brain Chemistries,Chemistries, Brain

D004331 Drosophila melanogaster A species of fruit fly frequently used in genetics because of the large size of its chromosomes. D. melanogaster,Drosophila melanogasters,melanogaster, Drosophila
D004744 Enkephalin, Methionine One of the endogenous pentapeptides with morphine-like activity. It differs from LEU-ENKEPHALIN by the amino acid METHIONINE in position 5. Its first four amino acid sequence is identical to the tetrapeptide sequence at the N-terminal of BETA-ENDORPHIN.

D004745 Enkephalins One of the three major families of endogenous opioid peptides. The enkephalins are pentapeptides that are widespread in the central and peripheral nervous systems and in the adrenal medulla. Enkephalin
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
