The role of macrophages in anti-tumor immune responses: pathological significance and potential as therapeutic targets.

Malignant tumors comprise various types of normal cells and tumor cells, and are infiltrated by large numbers of immune cells, including macrophages. The results of numerous studies on the function and significance of intratumoral macrophages (tumor-associated macrophages) suggest that these macrophages generally enhance tumor progression rather than act as anti-tumor immune agents. Although much remains unknown, in this review, we attempt to describe the role of macrophages in the tumor microenvironment, and discuss their potential mechanisms on the recent immunotherapy.
