Loss-of-Function in SMAD4 Might Not Be Critical for Human Natural Killer Cell Responsiveness to TGF- β
This study was carried out in accordance with approval of the Melbourne Health and Walter and Eliza Hall Institute of Medical Research's Human Research Ethics Committee (approval number: 2013.081). All subjects gave written informed consent for participation and publication. Results and Discussion TGF-β signaling in NK cells is associated with: phosphorylation in SMAD2 and 3, inhibition of IL-15-induced metabolism/proliferation, simultaneous downregulation of CD44, CD49e, and Eomes, and upregulation of CD16 and CD49a expression (7, 10). SMAD family member 4 (SMAD4) belongs to the SMAD family of transcript...
