CD80 and esophageal adenocarcinoma: In the LPS-stimulated setting, TCM from 2Gy irradiated oesophageal adenocarcinoma biopsies inhibited levels of CD54, compared to 0Gy patient-matched biopsies (p = 0.024), whereas, the levels of CD80, HLA-DR, CD86 and PD-L1 were not differentially altered (Fig. 3a).
