Densely Calcified Atypical Choroid Plexus Papilloma at the Cerebellopontine Angle in an Adult

Journal of Neurological Surgery Reports, 2013
Choroid plexus papilloma is a rare benign tumor accounting for 0.5% of all intracranial tumors. The majority of choroid plexus papillomas occur during the first 2 years of life in the ventricular system.

Characterization of choroid plexus in the preterm rabbit pup following subcutaneous administration of recombinant human IGF-1/IGFBP-3

Fluids and Barriers of the CNS, 2023
Insulin-like growth factor-1 (IGF-1) is essential for normal brain development and regulates essential processes of vascular maturation and stabilization. Importantly, preterm birth is associated with reduced serum levels of IGF-1 as compared to in utero

Choroid plexus perfusion and intracranial cerebrospinal fluid changes after angiogenesis

Journal of Cerebral Blood Flow and Metabolism, 2020
Recent studies have provided evidence that cortical brain ischemia may influence choroid plexus function, and such communication may be mediated by either traditional CSF circulation pathways and/or a possible glymphatic pathway. Here we investigated the

New experimental model of acute aqueductal blockage in cats: effects on cerebrospinal fluid pressure and the size of brain ventricles [PDF]

, 2009
It is generally assumed that cerebrospinal fluid (CSF) is secreted in the brain ventricles, and so after an acute blockage of the aqueduct of Sylvius an increase in the ventricular CSF pressure and dilation of isolated ventricles may be expected. We have

Glucose, Fructose, and Urate Transporters in the Choroid Plexus Epithelium

International Journal of Molecular Sciences, 2020
The choroid plexus plays a central role in the regulation of the microenvironment of the central nervous system by secreting the majority of the cerebrospinal fluid and controlling its composition, despite that it only represents approximately 1% of the ...

Telovelar approach for microsurgical resection of an unusually located choroid plexus papilloma in the luschka foramen of an infant – Case report and review of literature

Interdisciplinary Neurosurgery, 2020
Background: Choroid plexus tumors are rare intraventricular tumors. Most of these tumors are benign choroid plexus papillomas. Most common location of these tumors in pediatric population is lateral ventricle although posterior fossa located tumors are ...

Annexin A5 prevents amyloid-β-induced toxicity in choroid plexus: implication for Alzheimer’s disease

Scientific Reports, 2020
In Alzheimer’s disease (AD) amyloid-β (Aβ) deposits may cause impairments in choroid plexus, a specialised brain structure which forms the blood–cerebrospinal fluid (CSF) barrier.

Transport of thyroid hormones via the choroid plexus into the brain: the roles of transthyretin and thyroid hormone transporters

Frontiers in Neuroscience, 2015
Thyroid hormones (THs) are key players in regulating brain development. In humans, insufficient THs during gestation can lead to cretinism and mental retardation.

Altered iron metabolism is part of the choroid plexus response to peripheral inflammation. [PDF]

, 2009
Iron is essential for normal cellular homeostasis but in excess promotes free radical formation and is detrimental. Therefore, iron metabolism is tightly regulated.
