Do you like your covid-19 vaccines to give you a good dose of neutralising antibodies? You should because we've shown they correlate not only with protection from symptomatic but also severe disease! Another great collab with @DebCro https://www.nature.com/articles/s41467-023-37176-7

So much to like in this paper dissecting molecular pathogenesis of APDS1 & APDS2. Human <=> mouse. Curious how these rare monogenic PIDs will inform common polygenic autoimmune diseases like SLE. Dysregulation of PI3K pathway may not be so rare!

During antibody affinity maturation in germinal centers (GCs), many defective B cells die by apoptosis. These cells are removed by tingible body macrophages (TBMs). Here, we describe their origin and function. 🧵@NGurwicz https://doi.org/10.1084/jem.20222173 @JExpMed
