The coronavirus that causes COVID-19 may have devastating effects on brain cells, according to a new study. IN
The Oxford Immunology Network study hasspeculation that the coronavirus has been linked to various forms of brain damage, from inflammation to brain disease. They can cause confusion, memory changes and other consequences. However, scientists did not assume that the virus could invade brain tissue.

The virus enters the brain cells through the receptorACE2 located on the surface of the cell membrane. This receptor is expressed mainly in lung cells, which explains why coronavirus often causes pneumonia. However, scientists have found that a small amount of ACE2 in the brain still allows SARS-CoV-2 to penetrate into nerve tissues and cause pathological changes.
In addition, scientists, as manifestationsCOVID-19, described several cases of encephalitis (inflammation of the brain), as well as autoimmune reactions - immune cells attack healthy cells, perceiving them as foreign. This leads to muscle weakness and, in severe cases, paralysis.
