RNA-seq-based transcriptome analysis identifies TCR-expressing B1 cells as a multipotent lymphoid intermediate.
Classically, B and T lymphocytes are regarded as distinct lineages that can be readily distinguished by the receptors expressed on their surface. However, our recent study established that peritoneal B1 cells serve as precursors for extrathymic T cells through a TCR+CD19+ double-positive (DP) intermediate. To investiga...
