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 ...

Choroid Plexus Papilloma: A Case Report with Special Emphasis on Diagnosis and Pathology [PDF]

Journal of Clinical and Diagnostic Research
Choroid plexus papilloma is a rare, benign neuroepithelial tumour arising from the choroid plexus of the brain. It is reported to be more common in the lateral ventricles among paediatric populations and in the fourth ventricle in adults.

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

Histological Evidence for the Enteric Nervous System and the Choroid Plexus as Alternative Routes of Neuroinvasion by SARS-CoV2

Frontiers in Neuroanatomy, 2020
Evidence is mounting that the novel corona virus SARS-CoV2 inflicts neurological symptoms in a subgroup of COVID-19 patients. While plenty of theories on the route of neuroinvasion have been proposed, little histological evidence has been presented ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Choroid plexus volume enlargement in first-episode antipsychotic-naïve schizophrenia

Schizophrenia
Investigation of the choroid plexus in schizophrenia has seen growing interest due to its role in the interaction between neuroinflammation and brain dysfunction. Most previous studies included treated and long-term ill patients, while antipsychotics and

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.

Constitutive activation of canonical Wnt signaling disrupts choroid plexus epithelial fate

Nature Communications, 2020
The choroid plexus secretes cerebrospinal fluid and is critical for the development and function of the brain. In the telencephalon, the choroid plexus epithelium arises from the Wnt- expressing cortical hem.
