Unlabelled: Multidrug resistance is one of the biggest obstacles in the treatment of cancer. Recent research studies highlight that tumor microenvironment plays a predominant role in tumor cell proliferation, metastasis, and drug resistance. Hence, targeting the tumor microenvironment provides a novel strategy for the evolution of cancer nanomedicine. The blooming knowledge about the tumor microenvironment merging with the design of PEG-based amphiphilic nanoparticles can provide an effective and promising platform to address the multidrug resistant tumor cells. This review describes the characteristic features of tumor microenvironment and their targeting mechanisms with the aid of PEG-based amphiphilic nanoparticles for the development of newer drug delivery systems to overcome multidrug resistance in cancer cells.
From The Clinical Editor: Cancer is a leading cause of death worldwide. Many cancers develop multidrug resistance towards chemotherapeutic agents with time and strategies are urgently needed to combat against this. In this review article, the authors discuss the current capabilities of using nanomedicine to target the tumor microenvironments, which would provide new insight to the development of novel delivery systems for the future.

Agonistic anti-CD40 with anti-PD-1 can elicit objective responses in a small number of patients with pancreatic ductal adenocarcinoma (PDA). Better understanding of their individual effects on the PDA tumor microenvironment will help inform new strategies to further improve outcomes. Herein, we map tumor-specific CD8+ T-cell differentiation following agonistic anti-CD40 and/or anti-PDL1 in PDA.

Nanozymes, which are nanomaterials that replicate the catalytic activities of natural enzymes in biological systems, have recently demonstrated considerable potential in improving cancer immunotherapy by altering the tumor microenvironment. Nanozyme-driven immune responses represent an innovative therapeutic modality with high effectiveness and minimal side effects. These nanozymes activate the immune system to specifically recognize and destroy cancer cells.

Glioblastoma multiforme (GBM) is the most aggressive type of brain tumor, characterized by its heterogeneity in cellular components, including reactive astrocytes and microglia. Since neuroimmune responses like astrogliosis and microgliosis gain recognition as vital factors in brain tumor progression, there is a growing need for clinically relevant models that assess the interactions between astrocytes, microglia, and GBM. Here, a NEuroimmune-Oncology Microphysiological Analysis Platform (NEO-MAP) is presented as a "new map" to observe astrocytic scar formation and microgliosis in response to GBM.

Due to the complexity of the tumor microenvironment (TME), current tumor treatments cannot achieve satisfactory results. A nanocomposite material, UCNPs@PVP-Hemin-GOx@CaCO (UPHGC NPs) is developed that responds to the TME and controls release to achieve multimodal synergistic therapy in tumor tissues. UPHGC NPs mediate photodynamic therapy (PDT), chemodynamic therapy (CDT), and starvation therapy (ST) synergistically, ultimately inducing self-amplification of ferroptosis.

Irreversible electroporation (IRE) is a minimally invasive, non-thermal tumor ablation technique that induces nanoscale membrane perforation, leading to immunogenic cell death (ICD). However, IRE alone is limited by uneven electric field attenuation, incomplete tumor ablation, and the immunosuppressive nature of the tumor microenvironment. To address these challenges, a multifunctional nanomaterial, vermiculite nanosheets/calcium peroxide nanosheets (VMT/CaO NSs), is developed to enhance the efficacy of IRE.
