As shown in Supplementary Tables S2 and S3, OX40+ on TCs was related to moderately/well-differentiated differentiation and more frequently observed in tumors with negative lymph node, OX40L positivity on TCs was associated with advanced tumor stage, and positive OX40L expression on both TCs and macrophages was more often observed in tumors located in the body or neck of the pancreas. The gene discussed is TNFRSF4; the disease is neoplasm.
