Native serotonin 5-HT2C receptors are expressed as homodimers on the apical surface of choroid plexus epithelial cells.
G protein-coupled receptors (GPCRs) are a prominent class of plasma membrane proteins that regulate physiologic responses to a wide variety of stimuli and therapeutic agents. Although GPCR oligomerization has been studied extensively in recombinant cells, it remains uncertain whether native receptors expressed in their natural cellular environment are monomers, dimers, or oligomers. The goal of...
متن کاملExpression of P2X receptors in rat choroid plexus.
In this study, we have used reverse transcriptase polymerase chain reaction and immunocytochemistry to show that P2X1, P2X2, P2X4, P2X5, P2X6 and P2X7 receptor messenger RNA and protein are expressed in the rat choroid plexus taken from the fourth and lateral ventricles. In some epithelial cells, the apical surfaces were stained more intensely than the basal surfaces. Some of the epithelial cel...
متن کاملThe role of 5-HT2A and 5-HT2C receptors on harmalineinduced eating behavior in 24-h food-deprived broiler cockerels
This study was designed to examine the effects of intracerebroventricular (ICV) injection of ketanserin(5-HT2a receptor antagonist) and SB242084 (5-HT2c receptor antagonist) on harmaline induced feeding anddrinking response in 24-h food-deprived (FD24) broiler cockerels. At first, guide cannula was surgicallyimplanted in the right lateral ventricle of chickens. In experiment 1, birds were injec...
متن کاملQuantitative autoradiographic evidence for insulin receptors in the choroid plexus of the rat brain.
Techniques of in vitro receptor autoradiography were used to visualize binding of 125I-insulin on slices of frozen rat brain. Slide-mounted sections of frozen rat brain were incubated in 0.05 nM porcine 125I-monoiodoinsulin, alone or mixed with 1 microM unlabeled porcine insulin, ribonuclease, or glucagon, for 2 h at 22 degrees C. The labeled brain slices were apposed to LKB Ultrofilm to genera...
متن کاملI-45: Choroid Plexus Cyst
CPCs are a relatively common finding during the second trimester sonography. when a choroid plexus cyst is identified, the presence of structural malformation and other sonographic markers of aneuploidy should be assessed with a detailed fetal anatomic survey performed by an experienced person. if no other sonographic abnormalities are present, the CPC is considered isolated. given the consider...
