Decoding the Extracellular Vesicles-driven Communication in the Microenvironment of Hairy Cell Leukemia to Improve Patient Care Management

This study is investigating hairy cell leukemia (HCL), a rare type of blood cancer, by studying tiny particles called extracellular vesicles — small packages that cells release to communicate with each other. Researchers want to understand how cancer cells use these signals to survive and grow, with the goal of finding better treatments. **You may be eligible if...** - You are 18 years or older - You have been diagnosed with hairy cell leukemia (as defined by WHO 2022 criteria) - You are willing to sign informed consent - (Healthy volunteers are also eligible: adults aged 18+ in good general health) **You may NOT be eligible if...** - There are no specific exclusion criteria listed Talk to your doctor to see if this trial is right for you.
