C1q-mediated steric hindrance limits FcγR contribution to antibody-driven phagocytosis by human neutrophils

Max L.B. Grönloh, Lisanne de Vor, Seline A. Zwarthoff…·Suzan H. M. Rooijakkers

This study shows that complement proteins like C1q block FcγR engagement with IgG, reducing their role in neutrophil phagocytosis, while complement receptors still enhance bacterial clearance.

Identification of a C3b-specific nanobody that does not bind C3 and blocks alternative pathway convertases

Eva M. Struijf, Bart W. Bardoel, Joanne E. van Keulen…·Jamie S. Depelteau

This study identifies a C3b-specific nanobody that binds C3b but not C3, and inhibits the alternative pathway convertases of the complement system.
