[Immunosuppressive effect of a human serum ferroprotein of hepatic origin, alpha 2 H globulin. Study on blastic transformation of normal lymphocytes in the presence of phytohemagglutinin].
The alpha2 H globulin, a glycoferroprotein, has been found in the serum of patients with malignant diseases. Its level varies according to the evolution of the disease. The activity of this protein has been studied on the normal lymphocytes cultivated in presence of phytohemagglutinin. This study has showed that 5 mug/ml of alpha2 H globulin can inhibit the blastic transformation. The inhibitory effect is proportional to the amount of alpha2 H globulin added as judged by the tritiated thymidin incorporation. The study of morphological aspects of the lymphocytes shows that alpha2 H globulin acts upon the synthesis of the cytoplasmic proteins.
