FIGURE 2.

The expression of TIGIT, PD-1, and CD226 on T and NK and correlation in MDS and HD. Flow cytometry and statistical analysis of TIGIT, PD-1, and CD226 on T and NK in MDS and HDs by flow cytometry (A) and PCR (C). Correlation between TIGIT, CD226, and PD-1 expression level in MDS (B). Data are pooled from two independently acquired sets of samples. MDS, myelodysplastic syndromes; HDs, healthy donors; PB, peripheral blood; *P < 0.05, **P < 0.01, ***P < 0.005, ****P < 0.0001, NS, denotes not significant; data are presented as mean ± SD, Statistical differences between HD (N = 20) and MDS (N = 30) were determined by an unpaired t-test. Correlation coefficients (r) and p are indicated in the figure.
