Interestingly, a similar pattern as for the E7-dextramer staining was observed for IFN-γ secretion, i.e. the numbers of spot forming units (SFUs) were higher for cells isolated from the tumour tissue than from the spleen (more than 16-fold higher in the subcutaneous tumours, 13-fold higher in genital tract and almost 3-fold higher in lung lesions). Here, IFNG is linked to neoplasm.
