our results demonstrate direct lymphocyte cytotoxicity via a cytolytic molecule antigenically related to tnf-alpha and lymphokines activating mphi for amoebic killing by oxidative and non-oxidative mechanisms , the latter process mediated by a macrophage-activating factor ( maf ) distinct from interferon-gamma ( ifn-gamma ) .
