Targeting regulated cell death: Apoptosis, necroptosis, pyroptosis, ferroptosis, and cuproptosis in anticancer...

Area of Science:

• Immunology
• Oncology
• Cell Biology

Background:

• Regulated cell death (RCD) pathways are increasingly recognized for their role in modulating anti-tumor immunity.
• Tumor cells undergoing RCD can alter the tumor microenvironment (TME), potentially inhibiting cancer progression.

Purpose of the Study:

• To review the mechanisms of various RCD pathways (apoptosis, necroptosis, pyroptosis, ferroptosis, cuproptosis) and their interactions.
• To discuss how RCD activates antigen-presenting cells and T cells, thereby triggering anti-tumor immune responses.
• To summarize therapeutic strategies targeting RCD pathways in cancer treatment.

Main Methods:

• Literature review of RCD mechanisms and their impact on anti-tumor immunity.
• Analysis of the role of RCD in antigen presentation and T cell activation.
• Summary of drugs and nanoparticles targeting RCD pathways.

Main Results:

• RCD pathways influence the immunogenicity of the TME, impacting cancer progression.
• Specific RCD modalities activate key components of the anti-tumor immune response, such as CD8+ T cells.
• Novel RCD pathways present new therapeutic targets for cancer intervention.

Conclusions:

• Targeting RCD pathways offers promising strategies for enhancing anti-cancer immunity.
• Further research into the complex interplay of RCD and the TME is crucial for developing effective cancer therapies.
• Understanding and manipulating RCD holds significant potential for future cancer treatment paradigms.
