Llama mini-antibodies and their synthetic imitations
The ability of SARS-CoV-2 to infect cells depends on interactions between the viral spike protein and the human cell surface protein ACE2. To enable the virus to hook onto the cell surface, the spike protein binds ACE2 using three finger-like protrusions, called the receptor binding domains (RBDs). Blocking the RBDs therefore has the potential to stop the virus from entering human cells. This can be done using antibodies.
Nanobodies, small antibodies found in camels and llamas, are promising as tools against viruses due to their high stability and small size.
