Intratumor Performance and Therapeutic Efficacy of PAMAM Dendrimers Carried by Clustered Nanoparticles.

In recent years, small nanoparticles (NPs) with a diameter of less than 10 nm have aroused considerable interest in biomedical applications. However, their intratumor performance, as well as the antitumor efficacy, has not been well understood due to their size-dependent pharmacokinetics, which presents a formidable challenge for delivering a comparable amount of different small NPs to tumor tissues. Utilizing the multistage delivery strategy, we construct G3-, G5-, and G7-iCluster delivery systems by using poly(amidoamine) (PAMAM) dendrimers of different generations (G3-, G5-, and G7-PAMAM) as building blocks.

Nanoenabled Reversal of IDO1-Mediated Immunosuppression Synergizes with Immunogenic Chemotherapy for Improved Cancer Therapy.

Certain chemotherapeutics (e.g., oxaliplatin, OXA) can evoke effective antitumor immunity responses by inducing immunogenic cell death (ICD).
