CTLA-4 and PD-1 Ligand Gene Expression in Epithelial Thyroid Cancers

Figure 1

Relative expression levels of PD-L1, PD-L2, CD80, and CD86 mRNAs in PTC tissues. The fold changes were calculated considering the mRNA values of normal matched thyroid tissues equal to one. Referring to mRNA fold change, three groups are showed (i.e., reduced, unchanged, and increased). For each group, “n” indicates the number of cases. The small bars in the graph indicate the median values.
