Opsonization by non-neutralizing antibodies can confer protection to SARS-CoV-2 despite Spike-dependent modulation of phagocytosis

W. Bahnan, S. Wrighton, M. Sundwall, A. Bläckberg, O. Larsson, U. Höglund, H. Khakzad, M. Godzwon, M. Walle, E. Elder, L. Happonen, O. Andre, J. Kumra Ahnlide, T. Hellmark, V. Wendel-Hansen, , P. Nordenfelt

This study shows that non-neutralizing Spike-specific antibodies can enhance phagocytosis of SARS-CoV-2 by monocytes, potentially offering protection despite not neutralizing the virus.

Sweet revenge - Streptococcus pyogenes showcases first example of immune evasion through specific IgG glycan hydrolysis

A. Naegeli, E. Bratanis, C. Karlsson, O. Shannon, R. Kalluru, A. Linder, J. Malmström, M. Collin

This study identifies EndoS as a mechanism by which Streptococcus pyogenes evades the immune system by hydrolyzing IgG glycans, impairing antibody effector functions during infection.
