Cell Death and Disease

AbstractThe p75 neurotrophin receptor (p75NTR) is a known mediator of β-amyloid (Aβ)-induced neurotoxicity implicated in Alzheimer’s disease (AD). Here, we demonstrate that death receptor 6 (DR6) binds to p75NTR and is a component of the p75NTR signaling complex responsible for Aβ-induced cortical neuron death. Cortical neurons isolated from either DR6 or p75NTR null mice are resistant to Aβ-induced neurotoxicity. Blocking DR6 function in cortical neurons by anti-DR6 antibodies that block the binding of DR6 to p75NTR receptor complex or by a dominant negative DR6 construct lacking the cytoplasmic signaling death domain attenuates Aβ-induced caspase 3 activation and cell death. DR6 expression is upregulated in AD cortex and correlates with elevated neuronal death. Targeting the disruption of the DR6/p75NTR complex to prevent Aβ cytotoxicity represents a new approach for the treatment of neurodegenerative disorders such as AD.</jats:p
