Abstract: The inventors has developed a recombinant molecular system, named OptoFab, allowing the accurate control of the agonistic properties of an antibody-derived Fab fragment in time and in space using specific wavelengths of light. It consists in a Fab fragment derived from an agonistic antibody of interest, linked to optogenetic modules that confer a light response capacity. Indeed, antibody derived Fab fragments generally keep the specificity of the antibody for its epitope, but not its agonistic properties. However, when Fab fragments are oligomerized, they recover the agonistic properties of the whole antibody. These characteristics, are at the basis of the OptoFab concept as its objective is to manipulate the oligomerization/immobilization statue of a Fab fragment using optogenetics to control its agonistic property. The present invention relates to methods and systems for controlling the agonistic properties of antibody variable domains by light.
