Predominant Autoantibody Production by Early Human B Cell Precursors

Hedda Wardemann,1 Sergey Yurasov,1,3 Anne Schaefer,1 James W. Young,4 Eric Meffre,1,5* Michel C. Nussenzweig1,2*

Abstract: During B lymphocyte development, antibodies are assembled by random gene segment reassortment to produce a vast number of specificities. A potential disadvantage of this process is that some of the antibodies produced are self-reactive. We determined the prevalence of self-reactive antibody formation and its regulation in human B cells. A majority (55 to 75%) of all antibodies expressed by early immature B cells displayed self-reactivity, including polyreactive and anti-nuclear specificities. Most of these autoantibodies were removed from the population at two discrete checkpoints during B cell development. Inefficient checkpoint regulation would lead to substantial increases in circulating autoantibodies.
