Article Title: CCR5 expression and conformational stability as potential cooperative modulators of immune phenotypes and therapy response in breast cancer
doi: 10.1007/s12672-025-04189-1
Figure Lengend Snippet: Comprehensive characterization of CCR5 expression, predictive significance, functional pathways, and immune contexture in breast cancer. A Expression distribution of CCR5 across normal human tissues. B Multivariate logistic regression analysis showing that high CCR5 expression is independently associated with reduced likelihood of achieving pathological complete response (pCR) after neoadjuvant chemotherapy (NAC). C Sensitivity analysis using a data-augmented cohort confirms the negative association between CCR5 and pCR, with a narrower confidence interval. D Gene Ontology (GO) gene set enrichment analysis (GSEA) reveals that CCR5-high tumors are enriched in immune-related processes including T cell activation and leukocyte adhesion, as well as cellular transport and metabolic pathways. E Hallmark GSEA indicates concurrent activation of pro-inflammatory pathways (e.g., IFN-γ response, TNFα–NF-κB, IL6–JAK–STAT3) and tumor-promoting programs such as epithelial-mesenchymal transition (EMT) and mTORC1 signaling. F KEGG pathway enrichment highlights both immunostimulatory (e.g., NK cell cytotoxicity) and protumorigenic (e.g., PI3K–Akt signaling) pathways in CCR5-high tumors. G Immune cell infiltration analysis based on multiple algorithms shows that CCR5-high tumors are associated with elevated CD8⁺ T cells, M1 macrophages, and activated dendritic cells, but also with immunosuppressive Tregs, M2 macrophages, and high stromal/immune scores, suggesting a biphasic immune microenvironment
