Increased RAG expression may be a common feature of #early-life #B-lymphopoiesis that contributes to childhood B-ALL. We compared B-lymphopoiesis in early life vs. adult to be published soon. Will be great to define the fetal-exclusive features that make B cells more susceptible to B-ALL. #BYourCell

Another #nasal feature not discussed here is our finding that >70% of #COVID19 outpatients produced transient, virus-induced anti-IFNα autoantibodies in the nose, associated with BETTER outcomes www.science.org/doi/10.1126/.... Host's antiviral immunity rather than a breach of immune tolerance?

Transient anti-interferon autoantibodies in the airways are associated with recovery from COVID-19
Nasal IgA1 autoantibodies against IFN-α are associated with better COVID-19 prognosis, including fewer symptoms and robust anti–SARS-CoV-2 immunity.

FlowLITE: A protocol to characterize and quantify total antibody isotypes in human plasma using flow cytometry
FlowLITE is a flow cytometry bead-based assay that enables multiplexing and high-throughput quantification of all antibody isotypes from humans, mice, or other species, using small volumes of any fluid specimen. Here, we detail a FlowLITE protocol to quantify and characterize antibody light-chain and isotype expression in human plasma. We describe steps for titrating the capture and reveal antibodies, multiplexing assay beads, and staining samples. We then describe proced...
