Neurons are cool, but have you ever seen the choroid plexus?
The choroid plexus (in cyan) is a highly vascularized collection of cells inside the brain's ventricles. It produces spinal fluid (CSF) and forms a barrier between the blood🔴, CSF, and brain tissue🟣!

Choroid plexus is often lost during tissue sectioning and overall anatomy can be difficult if not impossible to reconstruct. Here we observe the vascular anatomy of human choroid plexus as if through a jeweler’s loupe. Sample courtesy of Matthew Schrag and Neil Dani. #FluorescenceFriday

The brain border regions (skull bone marrow, the meninges membrane layers, and choroid plexus) serve as an immune cell reservoir patrolling the brain. The persistence of spike protein here, getting into brain tissue, sets up an inflammatory response (as shown in mice in the current report)
