Neutrophil Dynamics in Response to Cancer Therapies

Area of Science:

• Oncology
• Immunology
• Cancer Biology

Background:

• Neutrophils are key immune cells within the tumor microenvironment (TME).
• Tumor-associated neutrophils (TANs) exhibit plasticity, polarizing into antitumor (N1) or protumor (N2) phenotypes.
• The influence of cancer therapies on TAN behavior is under-explored.

Purpose of the Study:

• To review the dynamic roles of TANs in response to various cancer treatments.
• To synthesize current knowledge on how chemotherapy, radiotherapy, and immunotherapies affect TANs.
• To highlight the potential for therapeutic reprogramming of TANs.

Main Methods:

• Comprehensive literature review of studies on TANs and cancer therapies.
• Analysis of how treatments influence TAN recruitment, polarization, and function.
• Identification of molecular regulators governing TAN responses to therapy.

Main Results:

• Cancer therapies significantly modulate TAN recruitment, polarization, and effector functions.
• Different treatment modalities exert distinct effects on TAN phenotypes within the TME.
• Key molecular pathways mediating therapy-induced TAN changes are identified.

Conclusions:

• TANs are critical modulators of cancer progression and treatment response.
• Understanding therapy-TAN interactions is crucial for developing novel cancer treatments.
• Reprogramming TANs offers a promising strategy to enhance therapeutic efficacy in cancer care.
