Camelid nanobodies: versatile tools for molecular and structural biology studies

In recent years, the use of single-domain camelid immunoglobulins, termed vHHs or nanobodies, has seen increasing growth in biotechnology, pharmaceutical applications and structure/function research. The usefulness of nanobodies in molecular and structural biology is now firmly established whether to solve 3D structures or to perform functional studies. After describing our platform dedicated to the selection and production of nanobodies, I will present the recent results we have obtained in the structural studies of bacterial secretion systems (T2SS, T6SS and T9SS). Finally I will present our current work on the development of neutralizing nanobodies against Ebola virus.
