Furthermore, we performed flow cytometric analysis of intracellular TNFα, IFNγ, and IL-2 on tumor-associated CD8+ cells after ex vivo stimulation with phorbol myristate acetate (PMA) and ionomycin, and we found that mifepristone treatment significantly increased expression levels of these three cytokines (Fig. 4o). Here, IFNG is linked to neoplasm.
