The heterogeneity of the tumor microenvironment is high.However, the role of plasma cells controlling the tumor migration progression in TNBC is still not fully understood.Methods: We analyzed single-cell RNA sequencing data from five HER2 positive, 12ER positive/PR positive, and nine TNBC samples. The potential targets were validated by immunohistochemistry.Results: Plasma cells were enriched in TNBC samples, which was consistent with validation using data from The Cancer Genome Atlas. Cell communication analysis revealed that plasma cells interact with T cells through the intercellular adhesion molecule 2–integrin–aLb2 complex, and then release interleukin 1 beta(IL1B), as verified by immunohistochemistry, ultimately promoting tumor growth.Conclusion: Our results revealed the role of plasma cells in TNBC and identified IL1B as a new prognostic marker for TNBC.展开更多
