CCL5 and CCR5 Interaction Promotes Cell Motility in Human Osteosarcoma
BACKGROUND Osteosarcoma is characterized by a high malignant and metastatic potential. CCL5 (previously called RANTES) was originally recognized as a product of activated T cells, and plays a crucial role in the migration and metastasis of human cancer cells. It has been reported that the effect of CCL5 is mediated via CCR receptors. However, the effect of CCL5 on migration activity and integri...
متن کاملThe CCL5/CCR5 axis promotes metastasis in basal breast cancer
Recently, we have shown that the CCL5/CCR5 axis is active in patients affected by an aggressive basal subtype of breast cancer. Using preclinical models, we have demonstrated that CCR5 promotes breast cancer invasiveness and metastatic potential, while CCR5 inhibition abrogates them. Thus, CCR5 antagonists may constitute an alternative therapeutic approach for patients affected by metastatic ba...
متن کاملTumor-derived chemokine CCL5 enhances TGF-β-mediated killing of CD8(+) T cells in colon cancer by T-regulatory cells.
Chemokine CCL5/RANTES is highly expressed in cancer where it contributes to inflammation and malignant progression. In this study, we show that CCL5 plays a critical role in immune escape in colorectal cancer. We found that higher levels of CCL5 expression in human and murine colon tumor cells correlated with higher levels of apoptosis of CD8+ T cells and infiltration of T-regulatory cells (T(r...
متن کاملCCL5 activation of CCR5 regulates cell metabolism to enhance proliferation of breast cancer cells
In earlier studies, we showed that CCL5 enhances proliferation and survival of MCF-7 breast cancer cells in an mTOR-dependent manner and we provided evidence that, for T cells, CCL5 activation of CCR5 results in increased glycolysis and enhanced ATP production. Increases in metabolic activity of cancer cells, specifically increased glycolytic activity and increased expression of glucose transpo...
متن کاملRNAi-Mediated CCR5 Knockdown Provides HIV-1 Resistance to Memory T Cells in Humanized BLT Mice
Transplantation of hematopoietic stem/progenitor cells (HSPC) modified with a lentiviral vector bearing a potent nontoxic short hairpin RNA (sh1005) directed to the HIV coreceptor CCR5 is capable of continuously producing CCR5 downregulated CD4+ T lymphocytes. Here, we characterized HIV-1 resistance of the sh1005-modified CD4+ T lymphocytes in vivo in humanized bone marrow/liver/thymus (hu BLT)...
