Immunohistochemistry for ICOS, TIGIT, TNFRSF8, and CD8A. Ovarian cancer samples (). Weak immunostaining scores for ICOS (a), TIGIT (c), TNFRSF8 (e), and CD8A (g) and strong immunostaining scores for ICOS (b), TIGIT (d), TNFRSF8 (f), and CD8A (h). The relative expression of the ICOS, TIGIT, TNFRSF8, and CD8A genes is depicted (i, j, k) (200).
