Research Overview

B lymphocytes are the ultimate effector cells of the humoural arm of the adaptive immune system, and the source of antibody. After their generation in the bone marrow, B lymphocytes emigrate to populate the periphery with mature cells specialised to respond to different classes of pathogens. We study the differentiation of B lymphocytes, and the roles played by important transcriptional regulators in this process. Two of the factors we focus on are B cell restricted proteins that interact through a conserved octamer DNA binding motif. They are the transcriptional regulators Oct-2 and OBF-1.

Research Interests

  • Molecular regulation of B lymphocyte activation, specialisation and terminal differentiation of antibody secreting plasma cells
  • B cell-specific transcription factors,in particular Oct-2 and OBF-1 (OCA-B/Bob.1)
  • Gene targeting approaches to gene function in vivo
  • Molecular regulation of plasma cell malignancy
  • Discovery of novel immunomodulatory drug
