From: HHLA2 predicts better survival and exhibits inhibited proliferation in epithelial ovarian cancer
Association of HHLA2 expression in ovarian cancer cells and CD8+ TIL status. The HHLA2 positive cells and CD8 positive cells were stained by IHC. a HHLA2 positive and c HHLA2 negative staining on ovarian cancer cells. b, d CD8 staining on ovarian cancer tissue slides. The red arrowhead indicated CD8+T cells. Magnification: × 200. A, B and C, D were from the same tumour tissue respectively. e The average CD8+ TIL number was compared between patients with negative HHLA2 expression and positive HHLA2 expression
