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...

Quercetin-3-glucuronide (Q3GA), the main phase II metabolite of quercetin (Q) in human plasma, is considered to be a more stable form Q for transport with bloodstream tissues, where it can potentially deconjugated by β-glucuronidase (β-Gluc) aglycone, which easily enters brain. This study evaluates effect lipopolysaccharide (LPS)-induced acute inflammation on β-Gluc gene expression choroid plex...

Purpose: To investigatemolecular alterations in choroid plexus tumors (CPT) using a genome-wide high-throughput approach to identify diagnostic and prognostic signatures that will refine tumor stratification and guide therapeutic options. Experimental Design: One hundred CPTs were obtained from a multi-institutional tissue and clinical database. Copynumber (CN), DNA methylation, and gene expres...

Several studies suggest the involvement of Na+ and HCO3- transport in the formation of cerebrospinal fluid. Two Na+-dependent HCO3- transporters were recently localized to the epithelial cells of the rat choroid plexus (NBCn1 and NCBE), and the mRNA for a third protein was also detected (NBCe2) (Praetorius J, Nejsum LN, and Nielsen S. Am J Physiol Cell Physiol 286: C601-C610, 2004). Our goal wa...

The choroid plexus epithelium is a cuboidal cell monolayer, which produces the majority of the cerebrospinal fluid. The concerted action of a variety of integral membrane proteins mediates the transepithelial movement of solutes and water across the epithelium. Secretion by the choroid plexus is characterized by an extremely high rate and by the unusual cellular polarization of well-known epith...

PURPOSE To assess the size of the choroid plexus in young children with unilateral and bilateral Sturge-Weber syndrome. METHODS Subjects included 15 children 4 years old or younger with Sturge-Weber syndrome. Eleven cases were unilateral and four were bilateral. Unilateral or bilateral involvement was determined by the distribution of abnormal leptomeningeal enhancement on MR images. The diam...

The choroid plexus epithelium secretes electrolytes and fluid in the brain ventricular lumen at high rates. Several channels and ion carriers have been identified as likely mediators of this transport in rodent choroid plexus. This study aimed to map several of these proteins to the human choroid plexus. Immunoperoxidase-histochemistry was employed to determine the cellular and subcellular loca...

The p73 proteins are present in different kinds of cells of the central nervous system, such as the choroid plexus, circumventricular structures and neuroepithelium. It has been reported that spontaneously hypertensive rats show ventricular dilation, changes in cerebrospinal fluid proteins and variations in the circumventricular structures such as the organum vasculosum of the lamina terminalis...
