In order to assess the effect of SB on the expression of IFN-γ-R1, a receptor involved in apoptosis and also in immune defense of CD8+ T cells, which produce IFN-γ to fight against cancer cells (15), we performed a staining for CD119 (IFN-γ-R1) on A549 cells treated with SB for 72h. Here, CD8A is linked to cancer.
