PSD-95/SAP90 antisense-treated animals not only experience a significant decrease in MAC for isoflurane, but also experience an attenuation in the NMDA-induced increase in isoflurane MAC. PSD-95/SAP90 appears to mediate the role of the NMDA receptor in determining the MAC of inhalational anesthetics. Suppression of the expression of PSD-95/SAP90 in the spinal cord significantly attenuates responses to painful stimuli mediated through the N-methyl-D-aspartate receptor activation. In spinal cord neurons PSD-95/SAP90 interacts with the N-methyl-D-aspartate receptor subunits 2A/2B. Activation of the N-methyl-D-aspartate receptor in spinal hyperalgesia results in association of the N-methyl-D-aspartate receptor with PSD-95/SAP90. PSD-95/SAP90 is required for hyperalgesia triggered via the N-methyl-D-aspartate receptor at the spinal cord level.
A method for relieving acute or chronic pain comprising:
A method for treating or inhibiting hyperalgesia comprising:
A method of reducing a threshold for anesthesia comprising administering intrathecally to a human in need thereof an effective amount of an antisense oligonucleotide which is complementary to mRNA encoding human post-synaptic density 93 protein (PSD93), which inhibits expression of human PSD93, whereby the desired anesthetic effect is achieved.
