CD8A and cancer: Researchers analysed the CSCC tissue microarrays of 116 patients using ISH and found that the expression of miR-142-5p was positively correlated with the number of indoleamine 2,3-dioxygenase (IDO)-positive lymphatic vessels (LVs) and total LVs around cancer and negatively correlated with the number of infiltrating CD8+ T cells.
