Through in situ transcriptomics of SS-TAMs of BL xenografts (5), we initially noted increased expression by TAMs of several members of the TYRO3/AXL/MERTK axis, including Mertk and Gas6, as compared with tingible body macrophages from germinal centers or paracortical lymph node macrophages. This evidence concerns the gene AXL and Burkitt lymphoma.
