CD8A and non-small cell lung carcinoma: Interestingly, Djenidi et al. have shown that ILC1 had an integrin profile (expression of CD103, integrin alpha E) and a memory-activated phenotype similar to that observed in tumor-infiltrating CD8+ T cells, which are tumor-tissue specific and whose presence correlates with improved early stage survival in patients with non-small-cell lung cancer (NSCLC) [49].
