title: [The palatine tonsils and immunity. Report VII. Soluble factors produced by the lymphocytes of the palatine tonsils in vitro].
abstract: A study was made of the production of a blastogenic factor and lymphotoxin in the cultures of lymphocytes of the palatine tonsils removed from patients with chronic tonsillitis; the activity of this blastogenic factor and lymphotoxin was studied in the test-cultures of autologous and allogenic lymphocytes and the transplantable HeLa cells. The antigens of the pathogenic streptococcus and staphylococcus induced production of the blastogenic factor and lymphotoxin; as to the antigens of saprophytic bacteria-they produced no such action. The antigen-specific blastogenic factor intensified the immune response to the homologous antigen, whereas the factor obtained in stimulation of lymphocytes with PHA-to all the microbial antigens under study.
