Stress, metabolism and cancer: integrated pathways contributing to immune suppression

Area of Science:

• Oncology
• Immunology
• Neuroscience

Background:

• Immune cells show potential for cancer control.
• Recent advances in immunotherapy demonstrate improved survival in advanced cancers by blocking immune suppression.
• Further research is needed to understand factors that inhibit anti-tumor immune activity.

Purpose of the Study:

• To review literature on stress and metabolic pathways, particularly those involving the sympathetic nervous system, that impede immune cell anti-tumor activity.
• To highlight the role of neurogenesis and adrenergic signaling in cancer progression and immune regulation.
• To underscore the need for further investigation into targeting systemic metabolic effects for enhanced cancer therapy.

Main Methods:

• Literature review of recent studies.
• Focus on interactive stress and metabolic pathways.
• Examination of sympathetic nervous system influence on immune cells.

Main Results:

• Sympathetic nervous system and stress pathways can suppress immune cell function.
• Tumor neurogenesis and adrenergic signaling impact cancer progression, cachexia, and lipolysis.
• These pathways influence immune cell differentiation and function.

Conclusions:

• The sympathetic nervous system plays a significant role in modulating the immune response to cancer.
• Understanding and targeting neuro-metabolic pathways is crucial for improving cancer immunotherapy.
• More research is required to fully leverage these systemic effects for therapeutic benefit.
