La région charnière des anticorps thérapeutiques

Abstract: La région charnière est une courte séquence des chaînes lourdes (H) d’anticorps liant le Fab (fragment antigen binding) au Fc (fragment crystallisable). Les propriétés fonctionnelles des quatre sous-classes d’immunoglobulines d’isotype G (IgG) résultent en partie des différences de séquence de leurs régions charnières. En effet, certains acides aminés de la partie C-terminale de ces régions charnières (« partie basse ») sont situés au sein ou à proximité des sites de liaison de la molécule C1q de la voie class… Show more

“…Preserving this structure during the modification process is crucial. The Fab regions can rotate about their axes, move in different directions at significant angles, bend, stretch, and contract to effectively engage with antigens [96,98]. Thus, the angle between the Fab regions modulates the accessibility of the antigen, and perturbations introduced during modification can reduce affinity.…”
