TIGIT expression was shown to be higher in CLL patients compared to Ps patients (409.6 vs. 109.9 p < 0.0001), as well as in CLL patients compared to HVs (409.6 vs. 19.41, p < 0.0001), and in Ps patients compared to HVs (109.9 vs. 19.41, p < 0.0001) (Figure 1f). This evidence concerns the gene TIGIT and B-cell chronic lymphocytic leukemia.
