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.

Macrophages undergo dynamic changes during different phases of wound healing. The adipose tissue of obese subjects shows a marked reduction in KLF4 levels. Epigenetic changes and noncoding RNAs also participate in directing macrophage polarization 32 — Abstract Diversity and plasticity are hallmarks of cells of the monocyte-macrophage lineage.

At later stages of progression in mice and humans, TAMs generally have an M2-like phenotype with low IL expression, high IL expression, and low tumoricidal activity and promotion of tissue remodeling and angiogenesis. Although further work is needed to dissect the diversity and dynamics of ATMs, M2-like cells in nonobese individuals are likely involved in maintaining adipose tissue homeostasis, preventing inflammation, and promoting insulin sensitivity.

Role of Kruppel-like factors in leukocyte development, function, and disease. Macrophage-specific PPARgamma controls alternative activation and improves insulin resistance. Macrophages in allergic asthma: Please review our privacy policy. Progress has now been made in defining the signaling pathways, transcriptional networks, and epigenetic mechanisms underlying M1-M2 or M2-like polarized activation.
