Cerebrospinal fluid secretion by the choroid plexus

Damkier, Helle H., Brown, Peter D., Praetorius, Jeppe·2013·Physiological Reviews

Abstract

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 epithelial transport proteins. This review focuses on the specific ion and water transport by the choroid plexus cells, and then attempts to integrate the action of specific transport proteins to formulate a model of cerebrospinal fluid secretion. Significant emphasis is placed on the concept of isotonic fluid transport across epithelia, as there is still surprisingly little consensus on the basic biophysics of this phenomenon. The role of the choroid plexus in the regulation of fluid and electrolyte balance in the central nervous system is discussed, and choroid plexus dysfunctions are described in a very diverse set of clinical conditions such as aging, Alzheimer's disease, brain edema, neoplasms, and hydrocephalus. Although the choroid plexus may only have an indirect influence on the pathogenesis of these conditions, the ability to modify epithelial function may be an important component of future therapies.

  • The ChP epithelial sheet, together with vasculature and diverse cell types, regulates CSF secretion and composition by de novo protein synthesis and selective transcytosis of blood-borne factors.

    “The foundation of the ChP is an epithelial sheet that, together with a network of vasculature and diverse cell types, regulates CSF secretion and governs its composition by de novo protein synthesis and selective transcytosis of blood-borne factors (Damkier et al., 2013; Ghersi-Egea et al., 2018; Lun et al., 2015a; Saunders et al., 2018b).”

  • The choroid plexus in each brain ventricle produces cerebrospinal fluid and forms the blood-CSF barrier.

  • Age-dependent expression of transporters and channels involved in ion and water movement across the epithelium was found.

    “We found age-dependent expression of transporters and channels involved in ion and water movement across the epithelium, aligning with a key function of epithelial cells to produce CSF (Damkier et al., 2013; Fame and Lehtinen, 2020).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
