Links on Alzheimer’s, diabetes, insulin and P38 MAPK

P38 MAPK can be activated by insulin. (1Insulin is also a growth factor; it is not just a hormone involved with sugar metabolism. Blocking Cannabinoid Receptor type 1 was found to inhibit the activation of P38 MAPK by insulin or insulin-like growth factor. (2) Malfunction of insulin’s growth factor function may be involved in Alzheimer’s Disease (3) as almost 200 pharmaceuticals designed to decrease levels of amyloid or tau protein have not been found effective for treatment of the disease in humans. (See previous post.) Mouse models may not be representative of the disease process in humans.
