Under the influence of tumor-derived factors, immune cells contribute to chronic inflammation and promote tumor growth. TNBCs are highly infiltrated by immune cells such as T lymphocytes and TAMs. Basal-like and triple-negative breast cancer (TNBC) cells, which are devoid of the estrogen and progesterone hormone receptors (HRs) and do not overexpress the human epidermal growth factor receptor 2 (HER2), is the most aggressive subtype. Even though breast cancer is well-characterized at cellular and molecular levels, the immune modulation in the tumor microenvironment (TME) remains to be better elucidated. Inflammation is a common facet of cancer that facilitates tumor progression and contributes to disease heterogeneity. In conclusion, our data indicate a self-reinforcing mechanism sustained by FN-EDA and IL-1β through NF-κB and STAT3 signaling in TAMs which fosters an inflammatory environment in TNBC. In the macrophages, the STAT3 pathway enhanced FN-EDA-induced IL-1β secretion and NF-κB signaling.

Conditioned media from TNBC cells induced the differentiation of CD206 +CD163 + macrophages and stimulated the STAT3 pathway, ex vivo.

TAMs were frequently observed in the tumor areas rich in FN-EDA. The proinflammatory cytokine IL-1β enhanced the expression of cellular fibronectin including FN-EDA. High levels of FN-EDA correlated with poor survival in breast cancer patients.

Cellular fibronectin (FN) harboring the alternatively spliced extra domain A (FN-EDA) was determined to be a matrix component produced by the triple-negative breast cancer (TNBC) cells.

This study aims to determine the impact of cellular fibronectin on inflammatory facets of tumor-associated macrophages (TAMs) in breast cancer.
