Covid Virus Endocytosis CGI image.   Endocytosis is a cellular process by which a cell takes in materials from its external environment by forming a vesicle around the material and then absorbing the vesicle into the cell.  With the COVID-19 virus, endocytosis refers to the process by which the virus enters host cells.  The virus first binds to specific receptors on the cell surface and is then taken into the cell through endocytosis.  Once inside the cell, the virus can replicate and cause damage to the host.  Endocytosis is a crucial step in the infectious cycle of many viruses, including SARS-CoV-2, the virus that causes COVID-19.
