The tumor microenvironment in NNKTL. NNKTL utilize CCL17/21, IL-9, IP-10, and soluble ICAM1 to proliferate/invade in an autocrine manner. These factors may be regulated by EBV LMP1. CD70 activation via soluble CD27 also mediate tumor proliferation. The downregulation of miR-15a mediates tumor progression by regulating surviving. Surrounding immune cells such as monocytes support NNKTL through IL-15 signaling.
