Cancer progression is often associated with an enhanced recruitment of myeloid-derived cells to the tumor microenvironment. Here we show that functional TGFβ-signaling in myeloid cells is required for metastasis to the lungs and the liver. Myeloid-specific deletion of Tgfbr2 resulted in reduced spontaneous lung metastasis, which was associated with a reduction of proinflammatory cytokines in the metastatic microenvironment. Notably, CD8+ T cell depletion in myeloid-specific Tgfbr2-deficient mice rescued lung metastasis. Myeloid-specific Tgfbr2-deficiency resulted in reduced liver metastasis with an almost complete absence of myeloid cells within metastatic foci. On contrary, an accumulation of Tgfβ-responsive myeloid cells was associated with an increased recruitment of monocytes and granulocytes and higher proinflammatory cytokine levels in control mice. Monocytic cells isolated from metastatic livers of Tgfbr2-deficient mice showed increased polarization towards the M1 phenotype, Tnfα and Il-1β expression, reduced levels of M2 markers and reduced production of chemokines responsible for myeloid-cell recruitment. No significant differences in Tgfβ levels were observed at metastatic sites of any model. These data demonstrate that Tgfβ signaling in monocytic myeloid cells suppresses CD8+ T cell activity during lung metastasis, while these cells actively contribute to tumor growth during liver metastasis. Thus, myeloid cells modulate metastasis through different mechanisms in a tissue-specific manner."}],"file":[{"access_level":"open_access","creator":"alisjak","file_name":"2021_Frontiers_Stefanescu.pdf","content_type":"application/pdf","checksum":"56cbac80e6891ce750511a30161b7792","relation":"main_file","date_created":"2021-12-13T13:32:37Z","file_size":9245199,"success":1,"file_id":"10539","date_updated":"2021-12-13T13:32:37Z"}],"type":"journal_article","day":"18","month":"11","article_processing_charge":"No","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2023-08-17T06:20:32Z","pmid":1,"quality_controlled":"1","title":"TGFβ signaling in myeloid cells promotes lung and liver metastasis through different mechanisms","status":"public","oa":1,"oa_version":"Published Version","date_created":"2021-12-12T23:01:27Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publisher":"Frontiers","scopus_import":"1","citation":{"mla":"Stefanescu, Cristina, et al. “TGFβ Signaling in Myeloid Cells Promotes Lung and Liver Metastasis through Different Mechanisms.” <i>Frontiers in Oncology</i>, vol. 11, 765151, Frontiers, 2021, doi:<a href=\"https://doi.org/10.3389/fonc.2021.765151\">10.3389/fonc.2021.765151</a>.","ieee":"C.
