The complement system is an important part of our immune system. It is a collection of proteins that attacks and eliminates pathogens. Piet Gros tries to recreate the complement system as accurately as possible. By placing the individual proteins in a crystal grid, he is able to study their shape and function.
Gros: "At the molecular level, we look at elements that are involved in this aspect of the immune system. We want to understand how danger is recognised at such a small level, and how this is turned into actions."
