A method of inhibiting the binding between N-methyl-D-aspartate receptors and neuronal proteins in a neuron is disclosed. The method comprises administering to the neuron an effective inhibiting amount of a peptide replacement agent for the NMDA receptor or neuronal protein interaction domain that effect said inhibition of the NMDA receptor—neuronal protein interaction. The method is of value in reducing the damaging effect of injury to mammalian cells. Postsynaptic density-95 protein (PSD-95) couples neuronal N-methyl-D-aspartate receptors (NMDARs) to pathways mediating excitotoxicity, ischemic and traumatic brain damage.
