B Lymphocyte Biology

B lymphocytes are key players of the immune response, mostly through the generation of a hugely diverse repertoire of protective antibodies that recognize pathogens and foreign molecules with exquisite specificity. However, misregulation of B lymphocyte function can also associate with multiple health conditions, including immune deficiencies, autoimmunity and cancer.

Our lab is interested in various aspects of B cell biology, in particular the regulatory and diversification events that take place in germinal centers. Diversification in germinal centers entails the remodeling of immunoglobulin genes and allows the generation of long-lived memory B cells and effector plasma cells. Thus, the germinal center response are responsible for improving the affinity and the memory immune response and underlie most of the vaccination strategies used worldwide.

Our most recent research has shown,

  • A new atherosclerosis-associated antigen that is target of protective antibodies (Nature 2021)
  • Germinal-center derived antibodies are important for the atheroprotection driven by MDA-LDL (Cell Reports 2022)
  • A pathway for the differentiation of plasma cells, using state-of-the-art single cell technology (EMBO Reports 2022)
