Where this comes from

Abstract

The malate shuttle is known to maintain the balance of NAD<sup>+</sup>/NADH between the cytosol and mitochondria. However, in T<sub>ex</sub> cells, it primarily detoxifies ammonia (via GOT1-mediated production of 2-KG in an atypical reaction) and provides longevity to chronic-infection-induced T<sub>ex</sub> cells against ammonia-induced cell death.
