Interestingly, plasma levels of pro-inflammatory cytokines IL-1β (Fig. 5a), TNF-α (Fig. 5b), and IL-2 (Fig. 5c) were significantly and negatively correlated with the numbers of CD4+NKG2D+ T cells in cervical cancer samples (IL-1β: Spearman ρ = -0.408; p = 0.023; TNF-α: Spearman ρ = -0.394; p = 0.028; IL-2: Spearman ρ = -0.522; p = 0.003). This evidence concerns the gene TNF and cervical cancer.
