Several age-related neurodegenerative diseases are a result of a decline in protein homeostasis as organisms age. Mitochondria, a vital organelle in the cell, is especially susceptible and thought to be a sensor of proteotoxic stress. Understanding how mitochondria communicate stress and recover homeostasis is therefore fundamental in developing novel treatments for age-onset human diseases. One way that mitochondria communicate stress is through the mitochondrial unfolded protein response (UPRmt). Important work has shown that stress can be communicated between tissues, such as from neurons to intestinal cells, called the “cell-non-autonomous UPRmt”. However, how stress is communicated is not entirely known. It is postulated that an unknown factor termed mitokine is responsible for... Read More
