Cholecystokinin-8 regulation of NGF concentrations in adult mouse brain through a mechanism involving CCK(A) and CCK(B) receptors.
1. Nerve growth factor (NGF), a powerful agent for the growth, differentiation and regeneration of lesioned cells of the central and peripheral nervous systems, has in recent years been indicated as a potential therapeutic agent capable of reversing the processes of cell damage in neurodegenerative events in man. Since NGF does not cross the blood-brain barrier and central NGF administration re...
متن کاملComparison of CCK-8 receptors in the pancreas and brain of rats using CCK-8 analogues.
The characteristics of cholecystokinin (CCK) receptors in rat pancreatic acini and in various regions of the brain were examined using synthetic CCK-8 or CCK-7 analogues. 3H-propionylated CCK-8 [( 3H]CCK-8) was used as a ligand. 1) The pancreatic CCK receptor had a single high affinity binding component with a dissociation constant, Kd, of 0.76 nM and a maximum number of specific binding sites,...
متن کاملAutoradiographical detection of cholecystokinin-A receptors in primate brain using 125I-Bolton Hunter CCK-8 and 3H-MK-329.
In vitro autoradiography was performed in order to visualize cholecystokinin-A (CCK-A) receptors in sections of Cynomolgus monkey brain. CCK-A receptors were defined as those which displayed high affinity for the selective non-peptide antagonist MK-329 (L-364,718) and were detected in several regions by selective inhibition of 125I-Bolton Hunter CCK using MK-329 or direct labeling with 3H-MK-32...
متن کاملMolecular cloning of the mouse CCK gene: expression in different brain regions and during cortical development
In this paper we describe experiments that address specific issues concerning the regulation of the mouse cholecystokinin gene in brain and intestine. The mouse cholecystokinin gene was cloned and sequenced. Extensive homology among the mouse, man and rat genes was noted particularly in the three exons and the regions upstream of the RNA start site. RNAse protection assays for each of the three...
متن کاملPancreatic function in CCK-deficient mice: adaptation to dietary protein does not require CCK.
A CCK-deficient mouse mutant generated by gene targeting in embryonic stem cells was analyzed to determine the importance of CCK for growth and function of the exocrine pancreas and for pancreatic adaptation to dietary changes. RIAs confirmed the absence of CCK in mutant mice and demonstrated that tissue concentrations of the related peptide gastrin were normal. CCK-deficient mice are viable an...
