M2 macrophages (M2 MC) are a subtype of macrophages that are generally associated with anti-inflammatory responses, tissue repair, and the promotion of tumor growth.
Strategies to reprogram M2 macrophages into a more pro-inflammatory M1 phenotype or to inhibit their function are being explored in cancer therapies.
M2 macrophages can play a dual role, promotion/suspression.
M2 macrophages are a subtype of macrophages that are generally associated with anti-inflammatory responses, tissue repair, and the promotion of tumor growth. The conversion of macrophages from the M1 (pro-inflammatory) to the M2 (anti-inflammatory) phenotype is a critical process in the tumor microenvironment and has significant implications for cancer progression.
M2 macrophages are generally considered protumorigenic. They secrete various cytokines and growth factors that promote tumor cell proliferation, angiogenesis, and tissue remodeling. Additionally, they can suppress the activity of cytotoxic T cells and natural killer (NK) cells, further aiding tumor immune evasion.
