Autophagy, ferroptosis, pyroptosis, and necroptosis in tumor immunotherapy

Signal Transduction and Targeted Therapy, Journal Year: 2022, Volume and Issue: 7(1)

Published: June 20, 2022

Abstract In recent years, immunotherapy represented by immune checkpoint inhibitors (ICIs) has led to unprecedented breakthroughs in cancer treatment. However, the fact that many tumors respond poorly or even not ICIs, partly caused absence of tumor-infiltrating lymphocytes (TILs), significantly limits application ICIs. Converting these “cold” into “hot” may ICIs is an unsolved question immunotherapy. Since it a general characteristic cancers resist apoptosis, induction non-apoptotic regulated cell death (RCD) emerging as new treatment strategy. Recently, several studies have revealed interaction between RCD and antitumor immunity. Specifically, autophagy, ferroptosis, pyroptosis, necroptosis exhibit synergistic responses while possibly exerting inhibitory effects on responses. Thus, targeted therapies (inducers inhibitors) against combination with exert potent activity, resistant This review summarizes multilevel relationship immunity RCD, including necroptosis, potential targeting improve efficacy malignancy.

Ferroptosis heterogeneity in triple-negative breast cancer reveals an innovative immunotherapy combination strategy

Cell Metabolism, Journal Year: 2022, Volume and Issue: 35(1), P. 84 - 100.e8

Published: Oct. 17, 2022

Treatment of triple-negative breast cancer (TNBC) remains challenging. Deciphering the orchestration metabolic pathways in regulating ferroptosis will provide new insights into TNBC therapeutic strategies. Here, we integrated multiomics data our large cohort (n = 465) to develop atlas. We discovered that TNBCs had heterogeneous phenotypes ferroptosis-related metabolites and pathways. The luminal androgen receptor (LAR) subtype was characterized by upregulation oxidized phosphatidylethanolamines glutathione metabolism (especially GPX4), which allowed utilization GPX4 inhibitors induce ferroptosis. Furthermore, verified inhibition not only induced tumor but also enhanced antitumor immunity. combination anti-PD1 possessed greater efficacy than monotherapy. Clinically, higher expression correlated with lower cytolytic scores worse prognosis immunotherapy cohorts. Collectively, this study demonstrated landscape revealed an innovative strategy for refractory LAR tumors.

Acidity‐Activatable Dynamic Nanoparticles Boosting Ferroptotic Cell Death for Immunotherapy of Cancer

Advanced Materials, Journal Year: 2021, Volume and Issue: 33(31)

Published: June 25, 2021

Abstract Immunotherapy shows promising therapeutic potential for long‐term tumor regression. However, current cancer immunotherapy displays a low response rate due to insufficient immunogenicity of the cells. To address these challenges, herein, intracellular‐acidity‐activatable dynamic nanoparticles eliciting by inducing ferroptosis cells are engineered. The engineered integrating an ionizable block copolymer and acid‐liable phenylboronate ester (PBE) covalent bonds tumor‐specific delivery inducer, glutathione peroxidase 4 inhibitor RSL‐3. can stably encapsulate RSL‐3 inside hydrophobic core via π–π stacking interaction with PBE groups at neutral pH (pH = 7.4), while releasing payload in endocytic vesicles 5.8–6.2) acidity‐triggered cleavage bonds. Furthermore, perform acid‐activatable photodynamic therapy protonation core, significantly recruit tumor‐infiltrating T lymphocytes interferon gamma secretion, thus sensitize RSL‐3‐inducible ferroptosis. combination nanoparticle‐induced blockade programmed death ligand 1 efficiently inhibits growth B16‐F10 melanoma lung metastasis 4T1 breast tumors, suggesting induction promoting immunotherapy.

Targeting ferroptosis opens new avenues for the development of novel therapeutics

Signal Transduction and Targeted Therapy, Journal Year: 2023, Volume and Issue: 8(1)

Published: Sept. 21, 2023

Abstract Ferroptosis is an iron-dependent form of regulated cell death with distinct characteristics, including altered iron homeostasis, reduced defense against oxidative stress, and abnormal lipid peroxidation. Recent studies have provided compelling evidence supporting the notion that ferroptosis plays a key pathogenic role in many diseases such as various cancer types, neurodegenerative disease, involving tissue and/or organ injury, inflammatory infectious diseases. Although precise regulatory networks underlie are largely unknown, particularly respect to initiation progression diseases, recognized bona fide target for further development treatment prevention strategies. Over past decade, considerable progress has been made developing pharmacological agonists antagonists these ferroptosis-related conditions. Here, we provide detailed overview our current knowledge regarding ferroptosis, its pathological roles, regulation during disease progression. Focusing on use chemical tools preclinical studies, also summarize recent advances targeting across growing spectrum ferroptosis-associated Finally, discuss new challenges opportunities potential strategy treating
