Fig. 6From: CD40/anti-CD40 antibody complexes which illustrate agonist and antagonist structural switchesOverlay of ABBV-323/CD40 complex (magenta = Fab/CD40 monomer 1, green = CD40 crystallographic monomer 2) with crystal structure of CD40L/CD40 complex (PDB code: 3QD6 in grey surface) [4]. Red outlined box shows the region of significant steric clash between CD40 dimer and CD40LBack to article page
