TNFRSF12A and leukemia: Surprisingly, the nearby naïve CD4 T cells (Figure 5D-E) and DCs (Figure 5F-G) had significantly higher expression of TNFRSF12A, which codes for the corresponding receptor TWEAKR (also known as FN14, CD266) than that of the same cell types at least 30 microns away from the closest leukemia cell.
