Knockout of the inhibitory receptor TIGIT enhances the antitumor response of ex vivo expanded NK cells and prevents fratricide with therapeutic Fc-active TIGIT antibodies by Dean A Lee, Jeremiah L Oyer, Md Faqrul Hasan, Tayler J Croom-Perez, Liza D Robles-Carrillo, Sanjana Kumar, Brendan W Andersen, Brian P Tullius, Alicja J Copik, Amanda R Campbell, Thomas A Dieffenthaller, Catherine A Cash, Jonathan E Eloriaga, Meisam Naeimi Kararoudi

“…Importantly, TIGIT KO prevented NK-cell fratricide when combined with Fc-active anti-TIGIT.Conclusions TIGIT KO in ex vivo expanded NK cells increased their cytotoxicity and metabolic fitness and prevented NK-cell fratricide when combined with Fc-active anti-TIGIT antibodies. These fratricide-resistant TIGIT KO NK cells have therapeutic potential alone or in combination with Fc-active anti-TIGIT antibodies to enhance their efficacy.…”
