Tumor Microenvironment Onmyoji: Cytokines with Dual Protumor and Antitumor Roles

Area of Science:

• Immunology
• Oncology
• Molecular Biology

Background:

• Cytokines are critical regulators within the tumor microenvironment (TME), influencing tumor initiation and progression.
• Many cytokines exhibit a dual nature, possessing both pro-tumor and anti-tumor properties, complicating therapeutic strategies.
• The transition from acute inflammation to chronic inflammation, driven by cytokines, promotes tumor progression and therapeutic resistance.

Purpose of the Study:

• To review the complex, dual functions of cytokines in the tumor microenvironment.
• To explore the evolution and regulation of cytokine activity during tumor progression.
• To provide insights for developing personalized cytokine-targeting immunotherapy strategies.

Main Methods:

• Literature review of current research on cytokines in the TME.
• Analysis of autocrine and paracrine mechanisms of cytokine action.
• Examination of factors influencing cytokine efficacy, including TME characteristics and immune cell responsiveness.

Main Results:

• Cytokines can activate anti-tumor immunity or promote immunosuppression and angiogenesis.
• Chronic inflammation, fueled by cytokines, contributes to therapeutic resistance.
• Challenges in cytokine therapy include poor persistence and significant toxic side effects.

Conclusions:

• Cytokine duality presents significant challenges for clinical translation of therapies.
• Reducing toxicity while enhancing efficacy is a primary goal in current cytokine research.
• Further understanding of cytokine regulation is crucial for advancing personalized immunotherapy.
