title: Failure to block lymphocyte Fc receptor with anti-B lymphocyte sera (anti-DRW) in man.
abstract: Sera harvested from multiparous women or from allograft recipients who had rejected their kidneys and containing various anti-DRW specificities, were studied on peripheral blood or lymph-node lymphocytes bearing or lacking the relevant B-cell alloantigen, for their EA or EAC-rosette-inhibition activity. Inhibition of C3 or Fc-receptor occurred independently of their anti-B lymphocyte cytotoxicity pattern. The same conclusion was reached when lymphocytes were either macrophage depleted or B-lymphocyte enriched. These results do not suggest a relationship in man between B-lymphocyte (DRW) alloantigen and Fc or C3 receptor structure.
