these findings suggest that the reduced cytotoxic ability of b-cll t-lymphocytes may be due either to an expanded population of immature t-cells which already express a cytotoxic-like phenotype ( e+ , okt3+ , hnk-1+ ) but which lack adequate cytotoxic functions , or , alternatively , to an intrinsic defect of the natural effectors present within the t-cell population of b-cll .
