Overview
Check whether patients with Hairy Cell Leukemia (HCL) of different status (at diagnosis, in complete remission > 2 years or relapsed requiring therapy) have a 'signature' of altered immunity based on extracellular vesicles (EV)
Description
Extracellular vesicles are small particles detected within plasma and recognized as mediators of intercellular communication thanks to their cargo of proteins, lipids, and nucleic acids. However, the composition of vesicles from Hairy Cell Leukemia patients, which may hold the key to unraveling their involvement and function within tumor microenvironment, is totally unknown. The aim of this study is to characterize these extracellular vesicles in order to identify biology-related and disease-specific biomarkers.
