Inhibitory ability of adherent blood cells from patients with chronic myeloid leukaemia on DNA-synthesis in non-adherent leukaemic cells and PHA-stimulated lymphocytes

Scandinavian Journal of Haematology

Abstract

Mononuclear blood cells were isolated from patients with different types of leukaemia and studied in vitro with regard to cell functions - adhesiveness, phagocytosis, DNA synthesis and inhibitory effects of adherent cells on non-adherent leukaemic cells and PHA stimulated lymphocytes. Cells from patients with chronic myeloid leukaemia (CML) adhered to the plastic surface of the culture dishes and showed esterase staining reactions as monocytes/macrophages. They showed a normal capacity to ingest Candida albicans, while the digestion capacity appeared reduced. Non-adherent cells from CML showed a high ability to incorporate thymidine, indicating DNA synthesis. Adhesive cells from patients with CML inhibited DNA synthesis in nonadherent CML cells and in PHA-stimulated lymphocytes to about the same extent as adhesive cells from normal donors. Blood cells from acute myeloid leukaemia and chronic lymphocytic leukaemia showed on adhesiveness and a very low spontaneous thymidine incorporation.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

B-cell leukemia includes various types of lymphoid leukemia that affect B cells. Here is the latest research on B-cell leukemia.

Candidiasis

Candidiasis is a common fungal infection caused by Candida and it can affect many parts for the body including mucosal membranes as well as the gastrointestinal, urinary, and respiratory tracts. Here is the latest research.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
