Decreased antibody-dependent cellular cytotoxicity in preleukemic syndromes

Abstract

In a previous report we showed decreased antibody-dependent cellular cytotoxicity (ADCC) activity of both leukemic and non-leukemic cells in human acute leukemia. In our present study, ADCC against tumor target cells was evaluated in 13 patients with preleukemic syndromes. ADCC was found to be significantly decreased in aplastic anemia, sideroblastic anemia, paroxysmal nocturnal hemoglobinuria and pure red cell aplasia, suggesting that impairment of immune defence capacity may precede the development of leukemia in man.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Adrenocortical Carcinoma

Adrenocortical carcinoma (ACC) is a rare malignancy of the adrenal cortex, associated with a generally dismal prognosis owing to its aggressive behavior. Here are the latest discoveries pertaining to this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Antibody-Dependent Cell Cytotoxicity

Antibody-dependent cellular toxicity refers to the lysis of a target cell by a non-sensitized effector cell of the immune system as a result of antibodies binding to the target cell membrane and engaging the Fc receptors on the immune effector cells.
