✦ Synopsis

Abstract

Mixed cultures of leukemic cells from acute lymphatic leukemia patients with autologous remission lymphocytes and of leukemic cells from both acute lymphatic leukemia patients and chronic lymphocytic leukemia patients with the lymphocytes from an HL‐A identical sibling were performed to investigate whether sensitization against leukemia‐associated antigens was demonstrable. Although in some cases marked thymidine incorporation was measured, this cannot be interpreted as stimulation by leukemia‐associated antigens, because it cannot be distinguished from non‐specific thymidine incorporation as was shown to occur sometimes in unstimulated cultures. It is concluded that the lymphocyte transformation technique is unsuitable for the detection of immunity to leukemia‐associated antigens.

## Abstract In vitro inhibition of monocyte spreading (a correlate of cellular immunity) was used to detect cell‐mediated immune reactions of melanoma patients to specific melanoma antigens. Two soluble preparations of human melanoma antigens (MA‐1 and MA‐2) and one of a breast carcinoma (BCA) were
