Phenotypical study of human lymphokine-activated killer (LAK) cells
1National Institute of Oncology and Radiobiology, Vedado, Cuba.
In the present study, T-cell enriched lymphocyte populations were stimulated with recombinant interleukin-2 (IL-2) to obtain lymphokine-activated killer (LAK) cells, and their cytotoxicity was tested against different target cells. The expression of phenotypical markers with a panel of monoclonal antibodies (Moabs) using indirect immunofluorescence techniques and cytofluorometric analysis was studied. The results showed slight variations in T-cell antigen expression and an increase in the expression of immature NK and proliferation associated antigens.
