Immunohistochemical studies on the gastrointestinal tract using antisera to Met-enkephalin and Met-enkephalin Arg6Phe7.
Antisera specific for the C-terminus of Met-enkephalin and two of its variants isolated from adrenal medulla and brain, namely Met-enk Arg6 and Met-enk Arg6Phe7, have been used in immunohistochemical studies of the gastrointestinal tract in rat, mouse and guinea pig. Met-enk and Met-enk Arg6Phe7-like immunoreactivities were found with similar distribution in nerve cell bodies of the myenteric p...
متن کاملImmunocytochemical and ultrastructural differentiation between Met-enkephalin-, Leu-enkephalin-, and Met/Leu-enkephalin-immunoreactive neurons of feline gut.
Selective immunocytochemical procedures, applied at the light and electron microscopical level, have resulted in the identification of three types of enkephalin-immunoreactive nerves in the feline gastrointestinal tract, including neurons containing either Met- or Leu-enkephalin immunoreactivity or those simultaneously storing both Met- and Leu-enkephalin immunoreactants. The three different ty...
متن کاملHamiltonian and distance replica exchange method studies of Met-enkephalin.
The conformational states of the zwitterionic form of the pentapeptide Met-enkephalin were explored with the use of explicit solvent molecular dynamics (MD). The N and C termini are ionized, as appropriate to polar solvent conditions, and consequently, there is a competition between open forms driven by polar solvation of the ammonium and carboxylate groups and closed forms driven by their salt...
متن کاملIntracerebroventricular met-enkephalin administration modulates adjuvant arthritis.
The purpose of this study was to investigate the anti-inflammatory properties of intracerebroventricular met-enkephalin (met-enk) administration in an animal model of arthritis. Adjuvant arthritis was induced in rats by intradermal inoculation of mycobacterium butyricum and the effects of intraventricular met-enk+thiorphan (enkephalinase inhibitor) were studied. Treatment was initiated either s...
متن کاملImproved bioavailability to the brain of glycosylated Met-enkephalin analogs.
The blood-brain barrier prevents the entry of many potentially therapeutic peptide drugs to the brain. Glycosylation has shown potential as a methodology for improving delivery to the CNS. Previous studies have shown improved bioavailability and improved centrally mediated analgesia of glycosylated opioids. In this study we investigate the effect of glycosylation on the cyclic opioid peptide [D...
