An extremely rare case of choroid plexus carcinoma in the third ventricle of an infant – Case report and review of the literature

Interdisciplinary Neurosurgery, 2020
Background: Choroid plexus tumors are rare intraventricular tumors. Most of these tumors are benign choroid plexus papillomas. Choroid plexus carcinoma is the most malignant choroid plexus tumor and constitutes a small percentage of these tumors.

The p75 neurotrophin receptor localization in blood-CSF barrier: expression in choroid plexus epithelium

BMC Neuroscience, 2011
Background The presence of neurotrophins and their receptors Trk family has been reported in the choroid plexus. High levels of Nerve Growth Factor (NGF), Neurotrophin-4 (NT-4) and TrkB receptor were detected, while nothing was know about p75 ...

Posthemorrhagic hydrocephalus associates with elevated inflammation and CSF hypersecretion via activation of choroidal transporters

Fluids and Barriers of the CNS, 2022
Introduction Posthemorrhagic hydrocephalus (PHH) often develops following hemorrhagic events such as intraventricular hemorrhage (IVH) and subarachnoid hemorrhage (SAH). Treatment is limited to surgical diversion of the cerebrospinal fluid (CSF) since no

c-MYC overexpression induces choroid plexus papillomas through a T-cell mediated inflammatory mechanism

Acta Neuropathologica Communications, 2019
Choroid plexus tumours (CPTs) account for 2–5% of brain tumours in children. They can spread along the neuraxis and can recur after treatment. Little is known about the molecular mechanisms underlying their formation and only few high fidelity mouse ...

Automated segmentation of choroidal layers from 3-dimensional macular optical coherence tomography scans [PDF]

arXiv, 2021
Background: Changes in choroidal thickness are associated with various ocular diseases and the choroid can be imaged using spectral-domain optical coherence tomography (SDOCT) and enhanced depth imaging OCT (EDIOCT). New Method: Eighty macular SDOCT volumes from 80 patients were obtained using the Zeiss Cirrus machine.

Single‐Cell Transcriptomes of Immune Cells from Multiple Compartments Redefine the Ontology of Myeloid Subtypes Post‐Stroke

Advanced Science, EarlyView.
Using single‐cell sequencing in a murine stroke model (p‐MCAO), three stroke‐specific subpopulations are identified: disease inflammatory macrophage (DIM), disease‐associated microglia (DAM), and CD14+ neutrophils (Neut_Cd14). Detailed analyses reveal that Neut_Cd14 and DIM subtypes are skull‐derived, whereas DAM likely originates from homeostatic ...

Analysis of retinal and choroidal images measured by laser Doppler holography [PDF]

, 2019
Laser Doppler holography (LDH) is a full-field imaging technique that was recently used in the human eye to reveal blood flow contrasts in the retinal and choroidal vasculature non-invasively, and with high temporal resolution. We here demonstrate that the ability of LDH to perform quantitative flow measurements with high temporal resolution enables ...

Transcriptomic Profiling Unveils EDN3+ Meningeal Fibroblasts as Key Players in Sturge‐Weber Syndrome Pathogenesis

Advanced Science, EarlyView.
Sturge‐Weber syndrome (SWS) is characterized by leptomeningeal vascular malformations, leading to seizures and stroke. Analysis of 119 446 brain cells from SWS patients uncovered distinct cell heterogeneity and identified an EDN3⁺ meningeal fibroblast cluster, with WNT5A emerging as a potential key driver of SWS progression and a promising therapeutic ...
