Immunological Function of Human Tonsils, With Special Reference to E- And Eac-Binding Lymphocytes

Abstract

This investigation was carried out to determine the immunological function of the human tonsil, especially the role of lymphocytes. The rosette-forming technique using sheep red blood cells and complement was used. Two types of E- and EAC-binding lymphocytes were found. Whereas the pattern of EAC-binding lymphocytes in human tonsil was similar to that in the peripheral blood, the percentage of E-binding lymphocytes was less. The percentages of rosette-forming cells in E or EAC suspensions appeared to be independent of age or sex. It was suggested that the human tonsil maintains a lifetime function through an immunocompetent system.
