The demise of cells in various ways enables the body to clear unwanted cells. Studies over years revealed distinctive molecular mechanisms and functional consequences several key cell death pathways. Currently, most intensively investigated programmed (PCD) includes apoptosis, necroptosis, pyroptosis, ferroptosis, PANoptosis, autophagy, which has been discovered play crucial roles modulating immunosuppressive tumor microenvironment (TME) determining clinical outcomes cancer therapeutic approaches. PCD can dual roles, either pro-tumor or anti-tumor, partly depending on intracellular contents released during process. also regulates enrichment effector regulatory immune cells, thus participating fine-tuning anti-tumor immunity TME. In this review, we focused primarily discussed messengers regulating their intricate crosstalk with response TME, explored immunological consequence its implications future therapy developments.

ZIF‐8 Nanoparticles Evoke Pyroptosis for High‐Efficiency Cancer Immunotherapy

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(10)

Опубликована: Янв. 11, 2023

Although zeolitic imidazolate framework-8 (ZIF-8) has been applied in various tumor therapies, the intrinsic immunogenicity remains unclear. Here, we initiatively discover that ZIF-8 nanoparticles (NPs) can intrinsically induce pyroptosis by a caspase-1/gasdermin D (GSDMD)-dependent pathway. The pyroptotic cell death is accompanied necrosis and immunogenic (ICD) simultaneously for efficient situ immunity initiation. Meanwhile, carbonyl cyanide m-chlorophenyl hydrazone (CCCP), mitochondrial depolarizing agent, successfully loaded into NPs found to further enhance process. Collectively, obtained Pluronic F127-modified CCCP-incorporated (F127 ZIF-8CCCP NPs) activate antitumor reprogram immunosuppressive microenvironment (TME), realizing high-efficiency growth inhibition.

Abstract Cancer immunotherapy and vaccine development have significantly improved the fight against cancers. Despite these advancements, challenges remain, particularly in clinical delivery of immunomodulatory compounds. The tumor microenvironment (TME), comprising macrophages, fibroblasts, immune cells, plays a crucial role response modulation. Nanoparticles, engineered to reshape TME, shown promising results enhancing by facilitating targeted These nanoparticles can suppress fibroblast activation, promote M1 macrophage polarization, aid dendritic cell maturation, encourage T infiltration. Biomimetic further enhance increasing internalization agents cells such as cells. Moreover, exosomes, whether naturally secreted body or bioengineered, been explored regulate TME immune-related affect cancer immunotherapy. Stimuli-responsive nanocarriers, activated pH, redox, light conditions, exhibit potential accelerate co-application with checkpoint inhibitors is an emerging strategy boost anti-tumor immunity. With their ability induce long-term immunity, nanoarchitectures are structures development. This review underscores critical overcoming current driving advancement modification.

Biodegradable Ca²⁺ Nanomodulators Activate Pyroptosis through Mitochondrial Ca²⁺ Overload for Cancer Immunotherapy

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(36)

Опубликована: Июнь 10, 2022

Abstract Pyroptosis provides a new direction and broad prospects for cancer immunotherapy. However, the development of nanoplatform as pyroptosis inducer is limited, discovery type nano‐pyroptosis immunotherapy still imminent. Herein, biodegradable Ca 2+ nanomodulators (CaNMs) are prepared inducers via mitochondrial overload. The obtained CaNMs can decompose under low pH to release curcumin, leading sudden surge in ions, eventually resulting pyroptosis. We not only confirm occurrence overload‐triggered first time but also reveal robust immune responses CaNMs, along with remarkably suppressing tumor proliferation lung metastasis. This work will provide strategies inspiration pyroptosis‐mediated treatments, greatly contributing further nanomodulators.
