Disentangling the complexity of tumor-derived extracellular vesicles

Michele De Palma, Tim Beltraminelli, Caleb Ricardo Perez

The tumor microenvironment encompasses an intertwined ensemble of both transformed cancer cells and non-transformed host cells, which together establish a signaling network that regulates tumor progression. By conveying both homo- and heterotypic cell-to-c ...

Biology and therapeutic targeting of tumour-associated macrophages

Michele De Palma, Tim Beltraminelli

Macrophages sustain tumour progression by facilitating angiogenesis, promoting immunosuppression, and enhancing cancer cell invasion and metastasis. They also modulate tumour response to anti-cancer therapy in pre-clinical models. This knowledge has motiva ...

Molecular profiling and functional analysis of macrophage-derived tumour extracellular vesicles

Tim Beltraminelli

Extracellular vesicles (EVs) are nanosized vesicles released by virtually all cell types. Increasing data suggest that EVs function in the regulation of intercellular communication both in physiological and pathological states. In cancer biology, mounting ...

Molecular Profiling and Functional Analysis of Macrophage-Derived Tumor Extracellular Vesicles

Michele De Palma, Romain Hamelin, Bruno Torchia, Chiara Cianciaruso, Sina Nassiri, Tim Beltraminelli

Extracellular vesicles (EVs), including exosomes, modulate multiple aspects of cancer biology. Tumor-associated macrophages (TAMs) secrete EVs, but their molecular features and functions are poorly characterized. Here, we report methodology for the enrichm ...
