Researchers Find the Switch that Underlies Macrophage Metabolism

  |  

In conclusion, the study revealed that the switch from a Myc-dependent to a HIF1α-dependent transcriptional program appears to regulate the robust bioenergetics support required for an inflammatory response. The switch allows for a rapid response to infection while simultaneously sparing Myc-dependent proliferation.

    Tips for Diagnosing Metabolic Myopathies

    When evaluating patients with possible myopathic symptoms, rheumatologists must consider a rare, but important, group of inherited disorders: the metabolic myopathies. However, their diagnosis often remains a challenge. Early recognition of these primary metabolic myopathies is essential to help prevent disease morbidity and mortality from rhabdomyolysis. Here, we focus on the metabolic myopathies that present…

    2015 ACR/ARHP Annual Meeting: Macrophage Polarization and Its Role in Inflammatory Disease

    SAN FRANCISCO—To unravel how out-of-control inflammation begins in rheumatoid arthritis and other diseases, one target for immunologists is the macrophage. Researchers discussed macrophage activation and other key drivers of inflammation at the 2015 ACR/ARHP Annual Meeting on Nov. 7. How macrophages behave when recognizing damage-associated molecular pathways (DAMPs) tells us more about why some inflammation doesn’t…
