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.

Alternative macrophage activation and metabolism. Sign up for email alerts. VEGF inhibitors can decrease macrophage recruitment, and this effect may contribute to their anti-angiogenic activity The interplay of polarized macrophages with stem and progenitor cells is likely a key component of their role in repair and remodeling, although the actual tissue-protective significance of polarized macrophages in degenerative diseases and their involvement with stem and progenitor cells remain to be determined see Supplemental References.
