Immune cells that infiltrate breast tumours exhibit a gene expression signature that is predictive of patient survival.

A team led by University of Melbourne researchers isolated more than 6,300 individual T cells from the tumours of two women with the particularly aggressive ‘triple-negative’ form of breast cancer. They then characterized all the RNA molecules in each immune cell and identified a distinct population of cells, known as tissue-resident memory T cells, that were associated with improved outcomes in a separate trial of patients with this form of breast cancer.

The findings could lead to new diagnostic tests to help guide treatment decisions for patients with breast cancer. Furthermore, drugs that boost the activity of these favourable immune cells may also improve responses to existing immunotherapeutic agents.
