Here we show that a key contribution to the suppression of lupus-like disease in BDF1 mice by NPs comes from NK cells and their TGF-β production. More recently, we showed that the delivery of IL‐2 and TGF-β to T cells via the use of nanoparticles (NPs) made with polymer poly(lactic‐co‐glycolic acid) (PLGA) could protect lupus mice from systemic autoimmunity by inducing Tregs - but also possibly modulating the activity of additional immune cells (10). <>>>/BBox[0 0 603 783]/Length 45>>stream Factor VII (FVII) Positive Control siRNA endobj McArdel SL, Terhorst C, Sharpe AH. endstream 33 0 obj endstream … siRNA Resuspension Protocol We recommend preparing 10 μM siRNA stock solution.
