Exploiting immunogenic cell death to promote antitumor immunity.

Area of Science:

• Immunology
• Oncology
• Cell Biology

Background:

• Immunogenic cell death (ICD) is a form of cell death recognized by the immune system.
• Distinct ICD modalities (apoptosis, pyroptosis, necroptosis, PANoptosis) release danger signals that alter the tumor microenvironment.
• Understanding ICD is crucial for developing effective cancer immunotherapies.

Purpose of the Study:

• To review how various ICD modalities activate antitumor immunity.
• To identify immune cell subsets involved in ICD-mediated responses.
• To discuss the clinical relevance of ICD, particularly in combination with immunotherapies.

Main Methods:

• Literature review of recent studies on immunogenic cell death.
• Analysis of distinct ICD pathways and their released danger signals.
• Examination of immune cell responses to ICD in the tumor microenvironment.

Main Results:

• ICD modalities release specific danger signals and cytokines that modulate immune cell composition.
• Acute ICD promotes antitumor immunity, while chronic inflammation can suppress it.
• ICD plays a significant role in the efficacy of current immunotherapies.

Conclusions:

• ICD is a critical bridge between tumor cell death and immune system activation.
• The temporal dynamics of ICD signaling are key to its beneficial effects.
• Combining ICD-inducing strategies with immunotherapies holds significant clinical promise.
