MACROPHAGE PLASTICITY AND POLARIZATION IN VIVO VERITAS PDF

The major pathways of macrophage polarization are outlined. The crosstalk between the M1-M2 macrophage–polarizing pathways is also. Polarized activation of cells of the monocyte-macrophage lineage into M1 and M2 cells is an operationally useful, simplified descriptor of the functional plasticity . Diversity and plasticity are hallmarks of cells of the monocyte-macrophage lineage. In response to IFNs, Toll-like receptor engagement, or IL-4/IL signaling.
