title: [Phytomitogen-induced lymphocyte transformation - standardization and diagnostic value (author's transl)].
abstract: Lymphocytes can transform into blasts. This basic biological property is the prerequisite for many reactions of the cellular immune system. Therefore, lymphocyte transformation tests appear to be a valuable diagnostic approach to define primary and secondary immundeficiency associated with different diseases. The validity of the test system is based on a standardization wich can be achieved sufficiently with regard to culture conditions and measurement of DNA-synthesis. But for phytomitogen-induced lymphocyte transformation a cooperative system of lymphocytes and macrophages is necessary. The results are influenced to a high degree by different cell separation procedures. Therefore, the interpretation of abnormal lymphocyte transformation data, induced unspecifically mitogens, has to take into account alteration of lymphocyte function, different T-/B-cell ratios and changing counts and helper effects of macrophages in order to define a defective lymphocyte transformation more precisely.
