Be1 and Be2 B cells are transcriptionally distinct

B cells cultured in the presence of Th1 CD4 T cells (Be1) or Th2 CD4 T cells (Be2) lead to distinct phenotypic outcomes. To determine when the phenotypic differences emerged, IgD positive and IgD negative Be1 and Be2 cells were isolated from cultures derived from 3 independent donors and RNA-seq performed. These data define the transcriptional differences of Be1 and Be2 cells ad distinct differentiation stages and show that Be1 B cells contain a pre-ASC signature that is absent from Be2 B cells. Overall design: Be1 and Be2 cells that were IgD positive and IgD negative from three different donors were analyzed by RNAseq.
