Pre-neoplastic cells in the brain release SDF1, which mediates an immediate infiltration of macrophages that differentiate into microglia-like cells and promote proliferation of pre-neoplastic cells.
The discovery of evolutionarily conserved macrophage subsets in zebrafish paves the way for a comprehensive study of macrophage behaviour and function.
Quantifiable bioenergetic parameters, determined from extracellular flux analyses, are distinct between macrophages infected with Mycobacteriumtuberculosis or vaccine strain M. bovis BCG, enabling assessment of future vaccine and drug efficacy.
The rapid killing of macrophages by Mycobacterium tuberculosis aggregates, and the subsequent proliferation of the bacteria inside the dead cell, leads to a cell death cascade and explains the coupling of necrosis and pathogen growth observed in active disease.
Activated macrophages initiate a robust DNA damage response that depends on type I IFN and regulates their genetic program and inflammasome activation, establishing a mechanistic link between DNA damage responses and innate immunity.
Interleukin 4 signaling co-opts the Akt-mTORC1-Acly pathway to couple metabolic input to the control of energetically demanding processes during macrophage M2 activation.
An unbiased forward genetic screen identified genes in Mycobacterium tuberculosis that are required for fatty acid import when the bacterium is residing within macrophages.
A detailed time-series analysis reveals that the interleukin-10 receptor prevents susceptibility to microbiota-driven colonic inflammation that emerges at the time of weaning by directly inhibiting the acquisition of a pro-inflammatory intestinal macrophage phenotype.
