The choroid plexus (ChP) is a highly vascularized structure comprising a monolayer of epithelial cells with microvilli that surrounds connective tissue and permeable capillaries in the brain ventricles [1]. The ChP is known to play a crucial role in producing cerebrospinal fluid (CSF) and in forming a permeability-regulating barrier between the blood and the CSF, known as the blood-CSF barrier [2]. Evidence has emerged that ChP volume is increased in patients with neurodegenerative disorders and…
