چکیده

The tumour microenvironment represents a dynamic complex milieu, which includes tumour cells, cells of the immune system and other (cellular and non-cellular) components. The role of these particular 'puzzle pieces' may change substantially due to their mutual interactions. The present review concerns different opinions on interactions that occur between monocytes, tumour cells and TMVs (tumour-derived microvesicles).

Tumour-derived microvesicles contain interleukin-8 and modulate production of chemokines by human monocytes.

BACKGROUND Tumour-derived microvesicles (TMVs) may interact with cells of the immune system. Our previous observations indicated that TMVs modulate production of cytokines and reactive oxygen species (ROS) by monocytes. This study was designed to determine the role of TMVs in stimulation of chemokine production by human monocytes. MATERIALS AND METHODS Chemokines at the mRNA and protein level...

Tumour-derived microvesicles (TMV) mimic the effect of tumour cells on monocyte subpopulations.

BACKGROUND Monocytes/macrophages may be affected by tumour cells via cell-to-cell contact, soluble factors and by tumour-derived microvesicles (TMV). Previous observations indicate that TMV interact with monocytes and alter their immunophenotype and activity. This study was designed to determine interactions of TMV with subpopulations (CD14(++)CD16(-) and CD14(+)CD16(++)) of human monocytes. ...

Molecular pathways: tumor-derived microvesicles and their interactions with immune cells in vivo.

Cancer is not merely a cell-intrinsic genetic disease but also the result of complex cell-extrinsic interactions with host components, including immune cells. For example, effector T lymphocytes and natural killer cells are thought to participate in an immunosurveillance process, which eliminates neoplastic cells, whereas regulatory T lymphocytes and some myeloid cells, including macrophages, c...

Tumor-released microvesicles as vehicles of immunosuppression.

Tumor-released microvesicles, or exosomes, which are abundant in the body fluids of patients with cancer, are likely to be involved in tumor progression. We recently showed that microvesicles released by human melanoma and colorectal carcinoma cells can promote the differentiation of monocytes to myeloid-derived suppressor cells which support tumoral growth and immune escape. These findings und...
