a) Representative flow cytometric diagram showing the increased expression of MHC class II on CD8+ T cells (activated) at 72 h HCC co-culture, b) CD8+ T cells exhibited higher activation at all time points compared to control PBMCs culture with a peak at 72 h. Also, the activation of CD8+ T cells in both HCC and non-HCC cocultures was higher compared to CD8+ T cells activation after isolation (0h).
