In the organoids, the team found that the virus could enter neurons through the ACE2 receptor, a protein on the cell surface that the virus uses to enter the cell and trigger infection.
They then used an electron microscope, which uses beams of charged particles to illuminate the tissue, to peer inside infected cells.
They could see coronavirus particles “budding” within the cell, demonstrating that the virus had hijacked the neurons’ internal machinery to build new copies of itself.
Other ways the virus can impede the body
In addition, some people have gastrointestinal (GI) symptoms, such as loss of appetite, nausea, vomiting, diarrhea, and abdominal pain or discomfort associated with COVID-19, notes Harvard Health.
