Abstract
English
Recent research on Hodgkin lymphoma has shown that the tumor microenvironment, particularly macrophages, plays a role in the development and progression of lymphomas. The underlying mechanisms and the potential therapeutic options arising from these findings remain largely unclear. Literature suggests that PI3K inhibitors may influence both HL cells and the tumor microenvironment. This study demonstrated a heterogeneous effect of the PI3Kγ/δ inhibitor Tenalisib on various HL cells, along with a shift in macrophage polarization towards M1 macrophages. Since the JAK/STAT signaling pathway plays a central role in HL cells, it was hypothesized that inhibiting this pathway could weaken HL cells and their influence on the tumor microenvironment when combined with PI3K inhibitors. Therefore, we investigated whether the JAK/STAT inhibitor Ruxolitinib enhances the effect of Tenalisib on the survival, proliferation, and tumor microenvironment of HL cell lines.
