Core Viewpoint - The research indicates that social interaction in mice can suppress breast cancer progression through a specific neural circuit, providing a potential theoretical basis for clinical applications of social support in tumor treatment [4][10]. Summary by Sections Research Findings - Social interaction activates neural circuits that inhibit breast cancer progression [8] - ACC Glu neurons are crucial for the anti-tumor effects of social interaction [8] - The ACC Glu → BLA Glu circuit mediates the anti-tumor benefits of social interaction [8] - Artificial activation of the social interaction circuit can enhance anti-tumor immune responses [8] Implications - The study suggests that social interaction may influence tumor progression by modulating sympathetic nerve activity and norepinephrine release, potentially reshaping anti-tumor immunity [6][10].
