Background: TIGIT
TIGIT is commonly used as a marker for T cell exhaustion and its expression correlates with disease progression. Furthermore, in viral infections including HIV and SIV, TIGIT serves as a target for immune restoration (6). In cancer detection, TIGIT is upregulated and coexpressed with programmed cell death protein 1 (PD-1) on the majority of circulating tumor antigen (TA)-specific CD8+ T cells (7). In addition to this, TIGIT can inhibit immune cells at multiple steps within the cancer immunity cycle. These include inhibiting NK cell effector function, suppressing dendritic cell costimulatory abilities, suppressing CD8+ T cell effector function by Tregs or polio virus receptor (PVR)-stimulated myeloid cells, and by directly inhibiting CD8+ T cells and preventing elimination of cancer cells (7).
