Proteomic and Functional Comparison of Extracellular Vesicles from Wild-Type and Lyn-Deficient Stromal Cells

Immune cells surrounding CLL tumors can be targeted through druggable proteins, opening new avenues to attack cancer's protective microenvironment.

A comprehensive proteomics study compared EVs from wild-type and Lyn-deficient CLL stromal cells, revealing profound alterations in ECM proteins, adhesion molecules, and signaling mediators with CD248 identified as a potential druggable stromal target. The work provides a translational framework for understanding how the CLL TME is reprogrammed by Lyn-dependent stromal signaling, with implications for therapeutic targeting of the CLL niche.
