The disproportional enlargement of the neocortex through evolution has been instrumental in the success of vertebrates, in particular mammals. The neocortex is a multilayered sheet of neurons generated from a simple proliferative neuroepithelium through a myriad of mechanisms with substantial evolutionary conservation. This developing neuroepithelium is populated by progenitors that can generate additional progenitors as well as post-mitotic neurons. Subtle alterations in the production of progenitors vs. differentiated cells during development can result in dramatic differences in neocortical size. This review article will examine how cadherin adhesion proteins, in particular α-catenin and N-cadherin, function in regulating the neural progenitor microenvironment, cell proliferation, and differentiation in cortical development.

Schlemm's canal endothelial cells (SECs) serve as the final barrier to aqueous humor (AQH) drainage from the eye. SECs adjust permeability to AQH outflow to modulate intraocular pressure (IOP). The broad identification of IOP-related genes implicates SECs in glaucoma.

Systemic capillary leak syndrome (SCLS) is a rare life-threatening disorder due to profound vascular leak. The trigger and the cause of the disease are currently unknown and there is no specific treatment. Here, we identified a rare heterozygous splice-site variant in the TLN1 gene in a familial SCLS case, suggestive of autosomal dominant inheritance with incomplete penetrance.

Neuropilin-1 (NRP1) regulates endothelial cell (EC) biology through modulation of vascular endothelial growth factor receptor 2 (VEGFR2) signalling by presenting VEGFA to VEGFR2. How NRP1 impacts VEGFA-mediated vascular hyperpermeability has however remained unresolved, described as exerting either a positive or a passive function. Using EC-specific Nrp1 knock-out mice, we discover that EC-expressed NRP1 exerts an organotypic role.

Article Synopsis
- Intracerebral calcium deposition includes primary familial brain calcification (PFBC), which leads to motor decline, speech difficulties, and cognitive issues, with limited treatment options available.* -
- Recent findings link PFBC to blood-brain barrier dysfunction, influenced by genetic variants that affect the neurovascular unit (NVU), leading to brain calcification.* -
- The review examines literature on genetic mutations in cell junction proteins related to brain calcification, aiming to identify molecular pathways and support the need for molecular subtyping in understanding this condition.*
