This change was accompanied by the upregulation of M1 surface markers (CD40, CD80) and M1 cytokines (e.g. TNFα, CXCL8). IL-36γ treatment of M2a macrophages also reduced the expression of TREM2 and CD36, two lipid-binding receptors that sustain the energy requirements of the M2 state.

Here, we characterise the effect of IL-27 on human blood derived CD14+ monocyte derived macrophages (MDMs), in resting state and under inflammatory stimulation (+LPS/PepG), through targeted transcriptomic expression profile, phagocytosis of <em>E. coli</em> bioparticles and expression of intracellular and secreted proteins by DIA mass spectrometry and multiplex ELISA, respectively.
