Integration of AIEgens into covalent organic frameworks for pyroptosis and ferroptosis primed cancer immunotherapy

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Sept. 2, 2023

Immunogenic programmed cell death, such as pyroptosis and ferroptosis, efficiently induces an acute inflammatory response boosts antitumor immunity. However, the exploration of dual-inducers, particularly nonmetallic inducers, capable triggering both ferroptosis remains limited. Here we show construction a covalent organic framework (COF-919) from planar twisted AIEgen-based motifs dual-inducer for efficient Mechanistic studies reveal that COF-919 displays stronger near-infrared light absorption, lower band energy, longer lifetime to favor generation reactive oxygen species (ROS) photothermal conversion, pyroptosis. Because its good ROS production capability, it upregulates intracellular lipid peroxidation, leading glutathione depletion, low expression peroxidase 4, induction ferroptosis. Additionally, by effectively inhibits tumor metastasis recurrence, resulting in over 90% growth inhibition cure rates exceeding 80%.

Heterostructural Nanoadjuvant CuSe/CoSe₂ for Potentiating Ferroptosis and Photoimmunotherapy through Intratumoral Blocked Lactate Efflux

Journal of the American Chemical Society, Journal Year: 2023, Volume and Issue: 145(13), P. 7205 - 7217

Published: March 23, 2023

The desirable curative effect in clinical immunotherapy has been challenging due to the immunosuppressive tumor microenvironment (TME) with high lactic acid (LA) metabolism solid tumors. Although targeting metabolic reprogramming of cells can restore survival and function immune TME, it is also plagued by insufficient immunogenicity. Herein, an activatable immunomodulatory nanoadjuvant CuSe/CoSe2@syrosingopine (CSC@Syro) constructed for simultaneously relieving TME boosting response. Specifically, CuSe/CoSe2 (CSC) exhibits TME-activated glutathione (GSH) depletion hydroxyl radical (•OH) generation potential ferroptosis. Meanwhile, remarkable photothermal conversion efficiency elevated photocatalytic ROS level both promote CSC heterostructures induce robust immunogenic cell death (ICD). Besides, loaded syrosingopine inhibitor achieves LA blockade cancer downregulating expression monocarboxylate transporter 4 (MCT4), which could sensitize ferroptosis intracellular milieu acidification neutralize acidic alleviate immunosuppression. Hence, advanced modulation confers potentiated infiltration ICD-stimulated T lymphocytes further reinforces antitumor therapy. In brief, CSC@Syro-mediated synergistic therapy elicit potent immunogenicity suppress proliferation metastasis effectually integrating regulation immunotherapy.

Abstract The term ferroptosis was put forward in 2012 and has been researched exponentially over the past few years. Ferroptosis is an unconventional pattern of iron-dependent programmed cell death, which belongs to a type necrosis distinguished from apoptosis autophagy. Actuated by phospholipid peroxidation, modulated various cellular metabolic signaling pathways, including amino acid, lipid, iron, mitochondrial metabolism. Notably, associated with numerous diseases plays double-edged sword role. Particularly, metastasis-prone or highly-mutated tumor cells are sensitive ferroptosis. Hence, inducing prohibiting vastly promising potential treating drug-resistant cancers. Immunotolerant cancer not traditional death pathway such as necroptosis, while crucial role mediating immune antagonize tolerance, broad prospects clinical setting. Herein, we summarized mechanisms delineated regulatory network ferroptosis, emphasized its dual proposed significant benefits microenvironment, ultimately presented some provocative doubts. This review aims provide practical guidelines research directions for practice immune-resistant tumors.
