The colonization comes with a substantial destruction of the surrounding host tissue. This leads to activation of damage responses by resident innate immune cells to protect, repair, and organize the wound healing, but may distract from tumoricidal actions. We recently demonstrated that microglia, innate immune cells of the CNS, assist carcinoma cell invasion. Here we report that this is a fatal side effect of a physiological damage response of the brain tissue. In a brain slice coculture model, contact with both benign and malignant epithelial cells induced a response by microglia and astrocytes comparable to that seen at the interface of human cerebral metastases. While the glial damage response intended to protect the brain from intrusion of benign epithelial cells by inducing apoptosis, it proved ineffective against various malignant cell types. They did not undergo apoptosis and actually exploited the local tissue reaction to invade instead. Gene expression and functional analyses revealed that the C-X-C chemokine receptor type 4 (CXCR4) and WNT signaling were involved in this process. Furthermore, CXCR4-regulated microglia were recruited to sites of brain injury in a zebrafish model and CXCR4 was expressed in human stroke patients, suggesting a conserved role in damage responses to various types of brain injuries. Together, our findings point to a detrimental misuse of the glial damage response program by carcinoma cells resistant to glia-induced apoptosis.

During breast cancer progression the colony stimulating factor 1 (CSF-1) can reprogram MCs into tumor-promoting macrophages in the primary tumor. However, the effect of CSF-1 during colonization of the brain parenchyma is largely unknown. Thus, we analyzed the outcome of anti-CSF-1 treatment on the resident macrophage population of the brain, the microglia, in comparison to MCs, alone and in different in vitro co-culture models. Our results underline the addiction of MCs to CSF-1 while surprisingly, microglia were not affected. Furthermore, in contrast to the brain, the bone marrow did not express the alternative ligand, IL-34. Yet treatment with IL-34 and co-culture with carcinoma cells partially rescued the anti-CSF-1 effects on MCs. Further, MC-induced invasion was significantly reduced by anti-CSF-1 treatment while microglia-induced invasion was reduced to a lower extend. Moreover, analysis of lung and breast cancer brain metastasis revealed significant differences of CSF-1 and CSF-1R expression. Taken together, our findings demonstrate not only differences of anti-CSF-1 treatment on MCs and microglia but also in the CSF-1 receptor and ligand expression in brain and bone marrow as well as in brain metastasis."],["dc.identifier.doi","10.18632/oncotarget.3855"],["dc.identifier.fs","618466"],["dc.identifier.pmid","26098772"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13609"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58709"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1949-2553"],["dc.rights","CC BY 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/3.0"],["dc.subject.mesh","Animals"],["dc.subject.mesh","Antibodies, Monoclonal"],["dc.subject.mesh","Brain"],["dc.subject.mesh","Brain Neoplasms"],["dc.subject.mesh","Breast Neoplasms"],["dc.subject.mesh","Cell Line, Tumor"],["dc.subject.mesh","Cell Movement"],["dc.subject.mesh","Cell Proliferation"],["dc.subject.mesh","Female"],["dc.subject.mesh","Humans"],["dc.subject.mesh","Interleukin-1"],["dc.subject.mesh","MCF-7 Cells"],["dc.subject.mesh","Macrophage Colony-Stimulating Factor"],["dc.subject.mesh","Macrophages"],["dc.subject.mesh","Mice"],["dc.subject.mesh","Mice, Inbred BALB C"],["dc.subject.mesh","Microglia"],["dc.subject.mesh","Monocytes"],["dc.subject.mesh","Neoplasm Invasiveness"],["dc.subject.mesh","Receptor, Macrophage Colony-Stimulating Factor"],["dc.title","Anti-CSF-1 treatment is effective to prevent carcinoma invasion induced by monocyte-derived cells but scarcely by microglia."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
