Killer T Cell Activity in the Paraneoplastic Neurologic Syndromes


Patients with paraneoplastic neurological disorders (PNDs) provide a unique model for
studying tumor immunity and neuronal autoimmunity. We hypothesize that T lymphocyte
autoimmune dysfunction is involved in the pathogenesis of the paraneoplastic neurological
syndromes, and that killer T cells are involved in the targeting and successful killing of
tumor cells in these cancer patients. Furthermore, we postulate that this activity may
provide a model for autoimmune brain disease. We will assess the immune responses in PND
patients, correlate these with the clinical data (time course of disease, symptoms and
signs, disability), and collect and archive clinical data, serum and cells from PND patients
for current and future studies into the basic immune system phenomenon present in PND
patients.
