Definition / general
  • Normal lymphoid cells undergo rearrangements within their antigen receptor genes causing specificity for the immunoglobulin or T cell receptor that they produce
  • Monoclonal proliferations are presumed to be neoplastic; polyclonal populations are not
  • Apoptosis helps eliminate B cells producing antibodies with low avidity
  • Lymphoid stem cell: TdT+, CD34+, HLA-DR+, then develops along B or T cell pathway
