Vidcast:  https://youtu.be/gkD-l35Izb0   The observation that 30 to 80% of CoVid patients experience neurologic symptoms may be explained by a new observation that CoVid spike proteins attack the integrity of the blood-brain barrier.  Pathologists from Philadelphia’s Temple University conclude this from their tissue culture studies.   Mixing CoVid19 spike proteins with blood vessel lining cells led to a protective layer breakdown that causes a potentially dangerous leakage through the brain’s protective coating.  Although the study stops short of demonstrating direct viral brain invasion, it suggests a mechanism by which that may happen.   The CoVid is definitely not a cold or the flu, so do all you can to protect yourself from it.   https://www.sciencedirect.com/science/article/pii/S096999612030406X?via%3Dihub   #covid #bloodbrainbarrier #spikeprotein
