Novel insights into the regulation of cellular catabolic metabolism in macrophages through nuclear receptors.

Abstract

Regulation of cellular catabolic metabolism in immune cells has recently become a major concept for resolution of inflammation. Nuclear receptors (NRs), including peroxisome proliferator activator receptors, 1,25-dihydroxyvitamin D (3) receptor, liver X receptors, glucocorticoid receptors, oestrogen-related receptor α and nuclear receptor 4A1, have been identified as major modulators of inflammation, affecting innate immune cells, such as macrophages. Evidence emerges on how NRs regulate cellular metabolism in macrophages during inflammatory processes and contribute to the resolution of inflammation. This could have new implications for our understanding of how NRs shape immune responses and inform anti-inflammatory drug design. This review will highlight the recent developments about NRs and their role in cellular metabolism in macrophages.
