The regulation of pre-metastatic niche formation by neutrophils
Metastasis is a multistep process requiring tumor cell detachment from the primary tumor and migration to target organs through the lymphatic or blood circulatory systems. Specific organs are predisposed to metastases in certain cancers and the formation of supportive metastatic microenvironment determines tumor cell homing. Such an environment is provided by a pre-metastatic niche that is form...
متن کاملEngineering the pre-metastatic niche
The pre-metastatic niche - the accumulation of aberrant immune cells and extracellular matrix proteins in target organs - primes the initially healthy organ microenvironment and renders it amenable for subsequent metastatic cell colonization. By attracting metastatic cancer cells, mimics of the pre-metastatic niche offer both diagnostic and therapeutic potential. However, deconstructing the com...
متن کاملHypoxia-driven immunosuppression contributes to the pre-metastatic niche
Primary tumor cells create favorable microenvironments in secondary organs, termed pre-metastatic niches, that promote the formation of metastases. Using immune competent syngenic breast cancer mouse models, we have recently demonstrated that factors secreted by hypoxic tumor cells condition pre-metastatic niches by recruiting CD11b+/Ly6Cmed/Ly6G+ myeloid cells and suppressing natural killer ce...
متن کاملTumor Exosomal RNAs Promote Lung Pre-metastatic Niche Formation by Activating Alveolar Epithelial TLR3 to Recruit Neutrophils.
The pre-metastatic niche educated by primary tumor-derived elements contributes to cancer metastasis. However, the role of host stromal cells in metastatic niche formation and organ-specific metastatic tropism is not clearly defined. Here, we demonstrate that lung epithelial cells are critical for initiating neutrophil recruitment and lung metastatic niche formation by sensing tumor exosomal RN...
متن کاملCarving out its niche: A role for carbonic anhydrase IX in pre-metastatic niche development
Primary tumor-associated hypoxia stimulates the production of secreted factors that mobilize bone marrow-derived cells, including immunomodulatory myeloid-derived suppressor cells (MDSCs) to pre-metastatic niches. We recently found that the hypoxia-induced enzyme carbonic anhydrase IX (CAIX) promotes metastasis by stimulating the G-CSF dependent mobilization of granulocytic MDSCs to the lung pr...
