A protocol for studying FcγRIIIa-driven events by therapeutic antibodies in human natural killer cells is described here. This artificial stimulation platform permits the interrogation of downstream effector functions such as degranulation, chemokine/cytokine production, and signaling pathways mediated by the FcγRIIIa and Fc portions of antibodies involved in binding.
