Cell competition in germinal centres
How do B cells acquire competitive fitness that can seed malignant transformation?
Germinal-centre B cells undergo rapid proliferation, mutation and stringent selection. The lab studies how mutations such as those affecting BTG1 alter competitive fitness, allowing abnormal clones to dominate otherwise regulated immune reactions.
Multi-allelic mouse models, patient-derived systems and primary human samples are used to connect altered competition with aggressive diffuse large B-cell lymphoma and to distinguish adaptive immune selection from malignant evolution.
