Research Group "Molecular regulation of B-cell development"

Prof. Dr. Hermann Eibel

Our group focuses on the development of human B cells and primary immune defects affecting B lymphocytes. Together with Klaus Warnatz and Uli Salzer we found that homozygous deletion of the BAFF-receptor gene may cause common variable immunodeficiency.

Research Areas

B lymphocyte development and primary immunodeficiencies

We study the development and the immune responses of human B lymphocytes. Primary immunodeficiencies represent an unlimited pool of mutations affecting the development of B cells, the formation of memory B cells and plasma cells and the production of antibodies. Analyzing the pathomechanisms leading to primary immunodeficiencies we are trying to understand the role and function of genes regulating human B cell development and homeostasis.

Projects:

  • In vitro and in vivo models of human B cell development
  • BAFF-receptor signaling,B cell survival and immune responses
  • Inherited defects affecting humoral immune response
