To see if the observed differences in tumour size and infiltration grade could be attributable to differences in the activation state of the transferred cells, we analysed the expression of different activation markers of this CD8+ Vα2/Vβ5+ T cell infiltrate and its potential response to the soluble OVA257–264 peptide in the tumour, analysing its ability to produce IFN-γ (Fig. 9). Here, CD8A is linked to neoplasm.
