Must know! Winter, weak body or strong germs?

The Harvard research team found that in normal conditions, cells in the upper respiratory tract, namely the nose and throat, form similar structures. with tiny fat particles released outside the cell all the time

These lipid particles are known as EVs or extracellular vesicles. Since these particles are released from the cell, they also carry proteins attached to the cell surface. This includes the proteins that the virus binds to enter cells, such as ACE2 that the SARS-CoV2 virus binds to, as well as in EVs. Therefore, the body produces EVs as a natural defense mechanism against viral infection.
