Choroid plexus and the blood-cerebrospinal fluid barrier in disease.

Fluids Barriers CNS 2020 May 6;17(1):35. Epub 2020 May 6.

Department of Anatomy, Cellular and Molecular Neurobiology Research Group, Faculty of Medicine, Masaryk University, CZ-625 00, Brno, Czech Republic.

The choroid plexus (CP) forming the blood-cerebrospinal fluid (B-CSF) barrier is among the least studied structures of the central nervous system (CNS) despite its clinical importance. The CP is an epithelio-endothelial convolute comprising a highly vascularized stroma with fenestrated capillaries and a continuous lining of epithelial cells joined by apical tight junctions (TJs) that are crucial in forming the B-CSF barrier. Integrity of the CP is critical for maintaining brain homeostasis and B-CSF barrier permeability. Read More

RBL1 (p107) functions as tumor suppressor in glioblastoma and small-cell pancreatic neuroendocrine carcinoma in Xenopus tropicalis.

Oncogene 2020 Mar 30;39(13):2692-2706. Epub 2020 Jan 30.

Department of Biomedical Molecular Biology, Ghent University, Ghent, Belgium.

Alterations of the retinoblastoma and/or the p53 signaling network are associated with specific cancers such as high-grade astrocytoma/glioblastoma, small-cell lung cancer (SCLC), choroid plexus tumors, and small-cell pancreatic neuroendocrine carcinoma (SC-PaNEC). However, the intricate functional redundancy between RB1 and the related pocket proteins RBL1/p107 and RBL2/p130 in suppressing tumorigenesis remains poorly understood. Here we performed lineage-restricted parallel inactivation of rb1 and rbl1 by multiplex CRISPR/Cas9 genome editing in the true diploid Xenopus tropicalis to gain insight into this in vivo redundancy.

Multiple Sclerosis and the Choroid Plexus: Emerging Concepts of Disease Immunopathophysiology.

Pediatr Neurol 2020 Feb 1;103:65-75. Epub 2019 Oct 1.

Division of Multiple Sclerosis and Neuroimmunology, Department of Neurology, McGovern Medical School, University of Texas Health Science Center at Houston, Houston, Texas. Electronic address:

Background: The coexistence of multiple sclerosis and intracranial neoplasms is very rare, and whether this occurrence can be explained by a causal relationship or by coincidence remains a matter of debate. Possible roles of the choroid plexus as a site of tumor cell invasion and lymphocyte infiltration into the central nervous system have been hypothesized in recent studies.

Methods: We describe a 13-year-old boy with concurrent multiple sclerosis and choroid plexus papilloma, then review the published literature with a focus on the pathophysiologic mechanisms of neuroinflammation in multiple sclerosis and the potential role of the choroid plexus in this process.

Distinct migratory pattern of naive and effector T cells through the blood-CSF barrier following Echovirus 30 infection.

J Neuroinflammation 2019 Nov 21;16(1):232. Epub 2019 Nov 21.

Pediatric Infectious Diseases, University Children's Hospital Mannheim, Medical Faculty Mannheim, Heidelberg University, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Germany.

Background: Echovirus 30 (E-30) is one of the most frequently isolated pathogens in aseptic meningitis worldwide. To gain access to the central nervous system (CNS), E-30 and immune cells have to cross one of the two main barriers of the CNS, the epithelial blood-cerebrospinal fluid barrier (BCSFB) or the endothelial blood-brain barrier (BBB). In an in vitro model of the BCSFB, it has been shown that E-30 can infect human immortalized brain choroid plexus papilloma (HIBCPP) cells. Read More

DNA methylation signature is prognostic of choroid plexus tumor aggressiveness.

Clin Epigenetics 2019 08 13;11(1):117. Epub 2019 Aug 13.

Genetics and Genome Biology Program, Hospital for Sick Children, PGCRL, 686 Bay Street, Toronto, Ontario, M5G 0A4, Canada.

Background: Histological grading of choroid plexus tumors (CPTs) remains the best prognostic tool to distinguish between aggressive choroid plexus carcinoma (CPC) and the more benign choroid plexus papilloma (CPP) or atypical choroid plexus papilloma (aCPP); however, these distinctions can be challenging. Standard treatment of CPC is very aggressive and often leads to severe damage to the young child's brain. Therefore, it is crucial to distinguish between CPC and less aggressive entities (CPP or aCPP) to avoid unnecessary exposure of the young patient to neurotoxic therapy. Read More

Management of choroid plexus tumors-an institutional experience.

Acta Neurochir (Wien) 2019 04 19;161(4):745-754. Epub 2019 Feb 19.

Department of Neurosurgery, Medical University of Vienna, Waehringer Guertel 18-20, 1090, Vienna, Austria.

Background: Choroid plexus tumors are rare entities. Resection is the mainstay of treatment in grade I and grade II tumors and adjuvant treatment is usually reserved for the less frequent choroid plexus carcinoma (CPC). Outcome is not only related to their histological grade but also dependent on their size, location, and presence of often multifactorial disturbances of cerebrospinal fluid (CSF) circulation.

Vanishing diffuse leptomeningeal contrast enhancement in an infant with choroid plexus papilloma.

Acta Neurochir (Wien) 2019 02 7;161(2):351-354. Epub 2019 Jan 7.

Department of Pediatric Neurosurgery, Hospital Sant Joan de Déu, Passeig Sant Joan de Déu 2, 08950, Esplugues de Llobregat, Barcelona, Spain.

Choroid plexus tumors (CPT) can present in the baseline magnetic resonance imaging (MRI) with lesions compatible with leptomeningeal dissemination. Therapeutic strategy in this condition is controversial. We present a case of an infant with CPP and significant diffuse leptomeningeal contrast enhancement at diagnosis, which spontaneously resolved after removal of the primary tumor. Read More

Early onset cerebral amyloid angiopathy following childhood exposure to cadaveric dura.

Ann Neurol 2019 02 17;85(2):284-290. Epub 2019 Jan 17.

Stroke Research Centre, Department of Brain Repair and Rehabilitation, University College London Queen Square Institute of Neurology and National Hospital for Neurology and Neurosurgery, London.

Amyloid-β transmission has been described in patients both with and without iatrogenic Creutzfeldt-Jakob disease; however, there is little information regarding the clinical impact of this acquired amyloid-β pathology during life. Here, for the first time, we describe in detail the clinical and neuroimaging findings in 3 patients with early onset symptomatic amyloid-β cerebral amyloid angiopathy following childhood exposure to cadaveric dura (by neurosurgical grafting in 2 patients and tumor embolization in a third). Our observations provide further in vivo evidence that cerebral amyloid angiopathy might be caused by transmission of amyloid-β seeds (prions) present in cadaveric dura and have diagnostic relevance for younger patients presenting with suspected cerebral amyloid angiopathy.
