Research Abstract |
Dysregulated insulin receptor signaling(insulin resistance) may be involved in dementia and neurodegenerative disease(e. g. Alzheimer's disease), thus insulin receptor signaling being the major molecular targets of neuroprotective drugs. In the present study, we have demonstrated that the insulin receptor signaling was up-and down-modulated by several therapeutic drugs and bioactive agents(e. g. nicotine, crucmin, docosahexaenoic acid, immunosuppressants and alchol) via multiple intracellular mechanisms.
