Myeloid-derived suppressor cells (MDSCs) are a type of immune cell that plays a significant role in cancer progression and immune evasion. They are a heterogeneous group of cells that are characterized by their ability to suppress the immune response, particularly the activity of T cells.
MDSCs are typically found in the tumor microenvironment and are thought to be recruited to the tumor site by various factors, including tumor-derived cytokines and chemokines. Once at the tumor site, MDSCs can suppress the immune response in several ways, including:
-Inhibiting the activation and proliferation of T cells.
-Suppressing the production of cytokines and chemokines that are necessary for an effective immune response.
-Inducing the production of anti-inflammatory cytokines that promote tumor growth and survival.
-Inhibiting the activity of natural killer (NK) cells and other immune cells that are important for tumor surveillance.
