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 papilloma

Asian Journal of Neurosurgery, 2017
Choroid plexus tumors are rare intracranial tumors which account for only 0.4-0.6% of all brain tumors. These are intraventricular papillary neoplasms derived from choroid plexus epithelium and range from choroid plexus papillomas (World Health Organisation (WHO) grade I) to choroid plexus carcinomas (WHO grade III).

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.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Growth Differentiation Factor 15 Elevation in the Central Nervous System Is Associated With Failure to Thrive in Alexander Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Alexander disease (AxD) is a severe neurodegenerative disorder caused by gain‐of‐function mutations in the gene for GFAP, which lead to protein aggregation and a primary astrocytopathy. Symptoms vary, but failure to thrive (FTT) and frequent emesis are common and cause significant morbidity. Here we investigate GDF15, a member of the
