In this episode, we learn about B cell maturation and class switching from

Hamish King. Hamish recently published apaper on this subject in Science Immunology, where he and his coauthorsanalyzed gene expression and antibody repertoire data from human tonsils.In the episode Hamish talks about some of the interesting B cell states heuncovered and shares his thoughts on questions such as «When does a B celldecide to class-switch?» and «Why is the antibody isotype correlated with itsaffinity?»
