Tat-HA-NR2B9c attenuate oxaliplatin-induced neuropathic pain.
    Experimental neurology, 2019, Volume: 311

    Oxaliplatin is a commonly used chemotherapy drug, which can produce acute and chronic peripheral neurotoxicity. Currently, there is no good therapeutic drug in clinic. Excessive stimulation of N-methyl-d-aspartate receptors (NMDARs) is crucial for the transmission of pain signals. However, directly inhibiting NMDARs can cause severe side effects because they have key physiological functions in the Central nervous system (CNS). Several years ago, we prepared a polypeptide Tat-HA-NR2B9c which can disturb NMDARs-postsynaptic density protein-95 (PSD-95) interaction. In this study, we studied whether Tat-HA-NR2B9c could be an effective treatment for oxaliplatin-induced neuropathic pain. To conform it, a rat model of oxaliplatin-induced neuropathic was established, and analgesic effect of Tat-HA-NR2B9c was studied. Here, we show that oxaliplatin induces the interaction of NMDARs with PSD-95. Uncoupling the complex by Tat-HA-NR2B9c has potent analgesic effect in oxaliplatin-induced cold hyperalgesia and mechanical allodynia without suppressing general behavioral. Tat-HA-NR2B9c neither inhibits NMDARs function nor impacts antitumor activity of oxaliplatin. Thus, this new drug may serve as a treatment for oxaliplatin-induced neuropathic pain, perhaps without major side effects.
