J Leukoc Biol. 2019 Jul;106(1):105-117. doi: 10.1002/JLB.3MIR1118-415R. Epub 2019 Feb 21.

Abstract

Cellular metabolism is a means of generating ATP to provide energy for key cellular functions. However, recent research shows that citric acid cycle intermediates target vital cellular functions of the innate immune system. Succinate, itaconate, citrate, and fumarate have been shown to mediate or regulate important myeloid cell functions during infection and inflammation. This review covers the regulatory functions of citric acid cycle intermediates in myeloid cells and discusses potential translational applications, key mechanistic questions, and future research directions.

Keywords: citrate; fumarate; itaconate; metabolic reprogramming; succinate.
