Nanomaterials-Involved Tumor-Associated Macrophages’ Reprogramming for Antitumor Therapy

Tumor-associated macrophages (TAMs) play pivotal roles in tumor development. As primary contents of tumor environment (TME), TAMs secrete inflammation-related substances to regulate tumoral occurrence and development. There are two kinds of TAMs: the tumoricidal M1-like TAMs and protumoral M2-like T...

Description
Summary:Tumor-associated macrophages (TAMs) play pivotal roles in tumor development. As primary contents of tumor environment (TME), TAMs secrete inflammation-related substances to regulate tumoral occurrence and development. There are two kinds of TAMs: the tumoricidal M1-like TAMs and protumoral M2-like TAMs. Reprogramming TAMs from immunosuppressive M2 to immunocompetent M1 phenotype is considered a feasible way to improve immunotherapeutic efficiency. Notably, nanomaterials show great potential for biomedical fields due to their controllable structures and properties. There are many types of nanomaterials that exhibit great regulatory activities for TAMs’ reprogramming. In this review, the recent progress of nanomaterials-involved TAMs’ reprogramming is comprehensively discussed. The various nanomaterials for TAMs’ reprogramming and the reprogramming strategies are summarized and introduced. Additionally, the challenges and perspectives of TAMs’ reprogramming for efficient therapy are discussed, aiming to provide inspiration for TAMs’ regulator design and promote the development of TAMs-mediated immunotherapy.
