“… 218 Likewise, expression of CEP55 has been positively correlated with the expression of more than 30 immune checkpoint genes in a wide range of solid tumors, as well as enhanced infiltration of immunosuppressive myeloid-derived suppressor cells and Th2 cells, expression of immunomodulators and response to immune checkpoint blockade. 219 , 220 , 221 Furthermore, high expression of PBK has been associated with immune escape due to upregulation of PD-L1 expression, dysregulation of antigen presentation and immune cell infiltration. 181 , 222 , 223 , 224 , 225 , 226 Of note, a subcluster of MAGE-A antigens has been reported to predict treatment response of melanoma tumors to immune checkpoint blockade.…”
