Functionally, EP stress is characterized by a decrease in chaperone BiP / GRP78 and an increase in the content of UPR sensors ATF6, IRE1, PERK, as well as an increase in neurons BAX-dimer, caspase-3 and a decrease in Bcl-xL. Pharmacological correction with metformin, propionate and their combination improves the condition of neurons and causes some compensation of EP stress. Propionate-induced autophagy due to the formation of vesicles from EP structures demonstrates an effective antiapoptotic mechanism of counteraction to stress by the ER degradation system and can be considered as a promising area of neuroprotection in diabetes mellitus2.
