these til microcultures were assessed for surface antigen phenotype , il 2 production ( helper function ) and for their cytolytic capabilities against the human erythroleukemic line k562 ( natural killer ( nk ) -like activity ) and p815 , a mouse mastocytoma line , in the presence of phytohemagglutinin ( pha ) , i.e. , lectin-dependent cell cytotoxicity ( ldcc ) which allows the detection of cytolytic activity irrespective of the antigenic specificity of the effector cells .
