Supramolecular Assemblies via Host-Guest Interactions for Tumor Immunotherapy.

Cancer immunotherapy has emerged as one of the most promising modalities for cancer treatment providing hopes of cancer patients with the significant advantages over traditional antitumor therapy methods. Supramolecular assemblies based on host-guest interactions have been widely explored in the field of cancer immunotherapy as the delivery systems. A variety of supramolecular materials show unique features for efficient drug encapsulation, targeting delivery and release, which are favorable to activate antitumor immune responses especially through combination of different treatment strategies. In this review article, we summarize the research progresses of supramolecular assemblies via host-guest interactions for tumor immunotherapy. The construction of various drug delivery systems including hydrogels, liposomes, and polymeric nanoparticles, the drug encapsulation and delivery, as well as advantages and disadvantages are discussed. The perspectives related to future developments in this field are also described.
