The virus causing Covid 19 makes important cells of the cerebrovascular system die

The National Institute of Medical Research of France informs that a team of different European scientists discovered how the virus SARS-CoV-2,the one causing Covid 19, affects important vascular cells of the brain which play an significant role in the correct working of the organ.    

According to the experts’ opinions when SARS-CoV-2 infects a group of endothelial cells, it “obliges” them to produce “a kind of molecular scissors” from their own genetic material, “cutting a protein called NEMO, that is essential for its survival”, so they died. 

As scientists detail, once the endothelial cells of the blood vessels die, they become in something known as “ghost vessels”, as they are empty, they lose their capacity of isolating the brain and the spinal cord from strange    substances. This could cause micro cerebral hemorrage.

Experts say that, as the number of ghost vessels increase the blood flow decreases in the affected areas, which provokes that other kind of cells from the brain do not receive oxygen and glucose, it causes failures, which could be fatal in the critical cases. 

Nevertheless as Vincent Prevot, who is a coauthor of the study, explains that the potential damage on the brain and the vascular structures affected could be reversible, as they have observed in the laboratory.  “We have seen it in hamsters that develop very slight forms of Covid- 19, the phenomenon is apparently reversible, and so we expect this to be in humans”.

The results of the research , that were recently published in Nature, make experts question themselves about the long term consequences in patients who had the Covid- 19 and their brains were not correctly irrigated. “They believe this situation could predispose some people who suffered the disease from developing cognitive failures, neurodegenerative failures and even dementias”.
