Intratumoral TIGIT blockade augments antitumor responses and bypasses increased functionality of peripheral TIGIT+ NK cells in mouse and human models of bone and soft tissue sarcoma
Background
TIGIT (T cell immunoreceptor with Ig and ITIM domains) has emerged as a key exhaustion marker of intratumoral natural killer (NK) cells, but results from clinical trials with TIGIT blockade have been largely negative. Recent data have sugge…
