TLR3 and TNBC in FUSCC datasets. The mRNA expression of TLR3 was lower in TNBC tissue than in the adjacent normal tissue (A). The TLR3 had high expression in immunomodulatory (IM) and mesenchymal-like (MES) subtypes and low expression in luminal androgen receptor (LAR) and basal-like immune-suppressed (BLIS) subtypes (B). The expression of TLR3 was positively associated with B cell, CD4 + T cells, CD8 + T cells, neutrophils, macrophages, and myeloid dendritic cells (C). TNBC with high TLR3 expression had a better prognosis than breast cancer with low TLR3 expression (D). TLR3: Toll-like receptor 3; FUSCC: Fudan University Shanghai Cancer Center; TNBC: triple-negative breast cancer; IM: immunomodulatory subtype; MES: mesenchymal-like subtype; LAR: low expression in luminal androgen receptor subtype; BLIS: basal-like immune-suppressed subtype; RFS: relapse-free survival
