背景介绍
TIGIT (T-cell immunoreceptor with Ig and ITIM domains), also known as VSIG9 or VSTM3, is an immune receptor expressed on T cells, including Treg and memory subsets, as well as on NK cells (PMID: 19011627). It contains an immunoglobulin variable domain, a transmembrane domain and an immunoreceptor tyrosine-based inhibitory motif (ITIM). TIGIT binds to poliovirus receptor (PVR, also called CD155) with high affinity, and also to PVRL2 (CD112) with lower affinity. The interaction of TIGIT with PVR on dendritic cells increases the secretion of IL-10 and decreases the secretion of proinflammatory cytokine and suppresses T-cell activation by promoting the generation of mature immunoregulatory dendritic cells. TIGIT can inhibit NK cytotoxicity directly through its ITIM (PMID: 19815499).

。例如，Demaria等人在外周血和支气管肺泡灌洗液中检测到较高水平的NK-19相关NK细胞中的NKG2A、PD-1和CD39。阻断NKG2A与其配体与抗NKG2A单克隆抗体的相互作用增强了COVID-19患者NK细胞的细胞毒性活性。另一方面，Krämer等人在一些COVID-19患者中检测到NK细胞上的TIGIT表达增加。TIGIT NK细胞比COVID-19患者的TIGIT NK细胞产生更多的IFN-γ。这些研究表明，COVID-19患者中NK细胞的活性受到抑制性检查点受体的抑制。 2. 使用离体扩增NK
