Here, we demonstrate nanoparticle (NP)-mediated knockdown of TGF-\u03b2 receptor 2 (TGFBR2) to improve NK cell function. Cationic manganese dioxide NPs (pMnO2-NP) that are 15nm complexed and protected siRNA from degradation. The pMnO2-NP-mediated siRNA delivery to NK cells resulted in 90% knockdown of the TGFBR2 receptor without cytotoxicity. Significantly, TGFBR2 receptor knockdown restored NK cell infiltration and killing of lung cancer cells even in the presence of TGF-\u03b21. Results from this study show the feasibility of increasing the resilience of NK cells to the immunosuppressive environments in solid tumors.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/bme.ufl.edu\/labs\/sharma\/files\/2019\/05\/BiomaterialsDay1-1024x1024.jpg\" alt=\"\" class=\"wp-image-1349\" srcset=\"https:\/\/faculty.eng.ufl.edu\/sharma\/wp-content\/uploads\/sites\/505\/2019\/05\/BiomaterialsDay1-1024x1024.jpg 1024w, https:\/\/faculty.eng.ufl.edu\/sharma\/wp-content\/uploads\/sites\/505\/2019\/05\/BiomaterialsDay1-300x300.jpg 300w, https:\/\/faculty.eng.ufl.edu\/sharma\/wp-content\/uploads\/sites\/505\/2019\/05\/BiomaterialsDay1-150x150.jpg 150w, https:\/\/faculty.eng.ufl.edu\/sharma\/wp-content\/uploads\/sites\/505\/2019\/05\/BiomaterialsDay1-768x768.jpg 768w, https:\/\/faculty.eng.ufl.edu\/sharma\/wp-content\/uploads\/sites\/505\/2019\/05\/BiomaterialsDay1-1536x1536.jpg 1536w, https:\/\/faculty.eng.ufl.edu\/sharma\/wp-content\/uploads\/sites\/505\/2019\/05\/BiomaterialsDay1.jpg 2001w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Isaac Adjei, a post-doctoral fellow in the Sharma Lab, presented his work at the 8th Annual UF Biomaterials Day Research Symposium on March 18th, 2019.
