  CD21 is a complement receptor (CR2) found on B cells and follicular dendritic cells that plays a key role in B cell activation and the immune response.
• D. B lymphocytes
  B lymphocytes are a type of white blood cell central to the adaptive immune system, responsible for producing antibodies and mediating humoral immunity.
• E. Parker immunity

Entity: idiotypic network theory
Triple: [Niels K. Jerne, developedTheory, idiotypic network theory]

Idiotypic network theory is an immunological concept proposing that the immune system is regulated by a dynamic network of interacting antibodies that recognize each other’s unique antigen-binding sites.
