This study reports cryo-EM structures of full-length BCRs, revealing their dynamic conformation and antigen binding-induced signaling mechanisms.

The paper shows that B cell receptor signaling sets limits on the selection of functional mutations in antibodies, with mid-affinity antigens showing optimal neutralization.

This study identifies binding dynamics as a key factor in enhancing germinal center responses to HIV immunogens, improving the efficiency of somatic hypermutation and bnAb precursor activation.

This study uses molecular dynamics simulations to design HIV-1 immunogens that select for specific mutations in broadly neutralizing antibodies.

This study shows that IgM and IgG1 BCRs differ in antigen sensing based on valency, with IgM preferring monovalent and IgG1 preferring polyvalent antigens, and identifies the CH1 domain as responsible for this difference.

This study shows non-neutralizing SARS-CoV-2 antibodies protect mice from severe disease via Fc-mediated effector functions, reducing viral load and lung damage.
