label_lc: decreased natural killer cell-induced killing of target cells
description: Abnormal decrease of natural killer (NK) cell cytotoxicity. Assaying NK cytotoxicity involves coculturing NK calls with target cells and measuring the extent of cell death by methods such as luminescence-based (luciferase) assays, biophotonic assays, and flow cytometry-based Cr-release assays.
