Diverse Neutrophil Functions in Cancer and Promising Neutrophil-Based Cancer Therapies

Area of Science:

• Immunology
• Oncology

Background:

• Neutrophils are the most abundant leukocytes, crucial for innate immunity and pathogen defense.
• Emerging evidence highlights neutrophils' complex roles in cancer immunity, displaying both pro-tumor and anti-tumor activities.
• The tumor microenvironment influences neutrophil functions through various mediators.

Purpose of the Study:

• To review current knowledge on neutrophil heterogeneity in cancer.
• To discuss tumor-neutrophil communication pathways.
• To explore the potential of neutrophil-based therapies for cancer treatment.

Main Methods:

• Literature review of recent studies on neutrophils in cancer.
• Analysis of neutrophil subpopulations and their functions.
• Examination of intercellular communication mechanisms between tumors and neutrophils.

Main Results:

• Neutrophils are not a homogeneous population; distinct subpopulations exist with varied roles in cancer.
• Tumor-derived factors modulate neutrophil behavior, leading to complex immune responses.
• Understanding neutrophil heterogeneity offers new therapeutic avenues.

Conclusions:

• Neutrophil heterogeneity significantly impacts cancer development and immune response.
• Targeting specific neutrophil functions or subpopulations holds promise for innovative cancer therapies.
• Further research into tumor-neutrophil interplay is essential for advancing cancer treatment strategies.
