CD40 and neoplasm: In the lung cells of tumour-bearing mice injected with E-cadherin + DCs, we showed that the percentage of CD8+ T cells expressing CD103 was approximately 15.2%, whereas those of mice injected with E-cadherin- DCs or PBS were approximately 3.7% and 0.51%, respectively (Figure 4C), suggesting that CD40-mediated inflammatory E-cadherin + DCs enhance CEA-specific, CD8+ T cell responses and the expression of CD103 by CD8+ T cells in the lung tumour immune microenvironment.
