| Outline of Final Research Achievements |
We aimed to clarify the pathology of diabetic polyneuropathy. Based on the finding that glucose responsive KATP channel (KATP), a target of insulin secretagogue sulfonyl urea (SU) drug, controls nerve excitability according to energy metabolic state, we investigated the physiological role of KATP in the peripheral nervous system.
As a result, it was revealed that SUs and KATP openers can exert neuroprotective action or conversely nerve injury action in dorsal root ganglion neuron cultures. In the KATP knockout mice, it was revealed that the peripheral nervous system declined at an earlier stage than the wild type mice with aging. Thus, it was suggested that KATP plays an important role in maintaining the peripheral nervous system.
