Another study by Pasero et al. [144] showed that tumor infiltrating NK cells in PCa patients are enriched in immature CD56bright cells (Figure 2J) that, while expressing markers of activation, are poorly cytotoxic and that TGFβ, an immunosuppressive cytokine abundant in PCa tissues, strongly regulate this process. The gene discussed is TGFB1; the disease is posterior cortical atrophy.
