Next Generation Sequencing Facilitates Quantitative Analysis of B cell Transcriptomes

Emergence of IgE antibodies that bind allergens with high affinity is highly correlated with the severity of anaphylaxis. However, the underlying molecular mechanisms by which high-affinity IgE is generated remain poorly understood. To examine function of IL-13 derived from T cells in IgE producing B cell development, we transferred IL-13 sufficient or deficient OT-2 TH2 into IgE reporter (Verigem) mice followed by immunization with NP-OVA. At 7 day post immunization, NP specific IgE producing B cells were sorted and served to single cell transcriptome analysis. Overall design: NP specific IgE+ B cells of mice were sorted and analyzed the transcriptome using Illumina NovaSeq 6000.
