چکیده انگلیسی
Peripheral neuropathy is a common adverse effect of bortezomib-based chemotherapy. In this study we have investigated the role played by subtype 5 of metabotropic receptors in bortezomib induced peripheral neuropathy. Rats were administered with bortezomib three times weekly at 0.20Â mg/kg for a total of 4 weeks in presence or absence of mGluR5 antagonist MPEP. The animals were submitted to paw-pressure test and tail sensory nerve conduction measurement more times during the treatment and follow-up. Bortezomib treatment induced a progressively increasing hyperalgesia in rat which was accompanied by a significant reduction in sensory nerve conduction velocity (SNCV). MPEP prevented the emergence of bortezomib-induced pain and counteracted SNCV reduction when co-administered with bortezomib treatment. Spinal extracellular glutamate levels increased in rats treated with bortezomib. Bortezomib-induced onset of the hyperalgesia and SNCV decrease could be prevented by agents that promote the reuptake of glutamate maintaining spinal glutamate at basal level. Our data support the manipulation of the glutamatergic system through the mGluR5 receptor in bortezomib induced peripheral neuropathy. The use of antagonists at the mGluR5, initiated at the same time as bortezomib-chemotherapy, might reduce the number of patients who develop painful peripheral chemo-neuropathy.
