Developing a nomogram based on SEER database for predicting prognosis in choroid plexus tumors

Scientific Reports
Choroid plexus tumors (CPT) are rare and highly vascularized neoplasms that have three histologically confirmed diagnoses, including choroid plexus papilloma, atypical choroid plexus papilloma, and choroid plexus carcinoma (CPC).

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Clinical Characteristics of Choroidal Metastases

Okulistyka
The most common intraocular tumors in adults are metastases from primary tumors: breast cancer, lung cancer, and other organ neoplasms. They are most typically located in the choroid, in the posterior pole of the eye.

An update on the landscape of collagen bioactive fragments

The FEBS Journal, EarlyView.
The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

Possibilities for Identifying the Malignant Vasculature of Choroidal Melanoma

Oftalʹmologiâ, 2020
Choroidal melanoma is the most common and life-threatening intraocular malignant neoplasm affecting the eye choroid in about 90 % of cases. The incidence varies from 0.7 to 1.1 per 100,000 of the population. This category of malignant neoplasms is highly

Variability in intracellular localization of D‐amino acid oxidase in choroid plexus epithelial cells

The FEBS Journal, EarlyView.
D‐amino acid oxidase (DAO) in choroid plexus epithelial cells (CPECs) shows vesicle‐like localization by histological and super‐resolution analyses. DAO colocalizes with peroxisomal, Golgi, endosomal, lysosomal, autophagosomal, and exosomal markers, indicating diverse subcellular distribution. This suggests DAO is transported within CPECs to metabolize

Atypical choroid plexus papilloma treated with single agent bevacizumab

Rare Tumors, 2014
Choroid plexus papillomas (CPPs) are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages.

Proteolytic remodelling of the extracellular matrix by pericytes

The FEBS Journal, EarlyView.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.
