The authors report the immunocytochemical localization in rat brain of affinity-purified anti-GluR3 (glutamate receptor) antibodies from two patients with Rasmussen encephalitis (RE) and from immunized rabbits. The distribution of immunolabeling was similar using antibodies from rabbits and patients with RE. No electrophysiologic responses were elicited from acutely dissociated kainate-responsive neurons isolated from rat brain when these antibodies were applied. These findings show that anti-GluR3 antibodies purified from patients with RE bind to specific regions of the CNS but do not act through an excitotoxic mechanism.
