In addition, coculture of ovalbumin (OVA)‐expressing mouse lung cancer cells with mouse CD8+ T cells expressing a transgenic T cell receptor (TCR) specific for an ovalbumin peptide showed that the acetate‐treated tumor cells inhibited the expression of interleukin‐2 and interferon‐γ in CD8+ T cells. Here, CD8A is linked to neoplasm.
