NFKB1 and nasopharyngeal carcinoma: Additionally, both EDAR knockdown and NFκB inhibitor pretreatment weakened T cell cytotoxicity against NPC cells (Figure 5H; Figure S5G, Supporting Information), reduced the number of T cells recruited by tumor cell supernatants (Figure 5I; Figure S5H, Supporting Information), and decreased the proportion of GZMB+CD8+ T cells in the supernatant‐treated T cell population (Figure 5J; Figure S5I, Supporting Information).
