The increased number of CD5+ B-cells in some human autoimmune diseases, the frequent commitment of CD5+ B-cells to the production of natural autoantibodies, and the apparent involvement of these cells in the pathogenesis of the autoimmune hemolytic anemia (AIHA) in certain mouse models suggests a causal relationship between the CD5+ chronic lymphocytic leukemia (CLL) B-cell and the AIHA which frequently develops in this malignant disorder.
