GW4869-treated Thy-1.1+ DUC18 CD8+ T cells exhibited lower EV production (Fig. 6b), whereas the degree of infiltration into subcutaneous CMS5a tumours was comparable to the untreated control (DMSO-treated) on the day after intravenous transfer (Fig. 6c, left large photo), indicating that tumour infiltration of CD8+ T cells was not altered by GW4869 treatment. Here, CD8A is linked to neoplasm.
