Pregnancy Recruits Killer T Cells That Guard Breasts Against Cancer for Years
Key Takeaways
- Pregnancy recruits tissue-resident memory T cells (killer T cells) to breast tissue.
- These cells persist for at least 10 years post-pregnancy, providing long-term cancer surveillance.
- Hormone treatments in experimental models mimicked pregnancy changes and induced protective T cells without conception.
- The study offers hope for immune-preventive interventions for women who cannot or choose not to have children.
