According to the different phenotypes and distinct patterns of gene expression, macrophages can be subdivided into two types: M1 and M2. The M1 macrophages, which are activated through the classical pathway, have a proinflammatory characteristic, providing an in-front defense line against different kinds of pathogens as well as malignant cells. On the other hand, the M2 macrophages are immunosuppressive and instead can promote tumor growth and dissemination. The solid tumor tissues are often infiltrated with a large number of macrophages, the so-called tumor-associated macrophages (TAMs). TAMs, which are polarized into M2 phenotype under the tumor microenvironment, promote tumor progression by …
