CD8A and neoplasm: Moreover, inhibition of neutrophil ferroptosis increased the proportions of effector CD8+ T cells, natural killer cells, and resident memory cells in TME, and synergy between Liproxstatin‐1 treatment and blocking PD‐1 was also observed.[21] LLI (+) combined with anti‐PD‐1 antibody treatment was found to be most effective in inhibiting tumor growth, which clearly demonstrated that Icy7 and Liproxstatin‐1 acted synergistically to contribute to anti‐PD‐1 antibody therapy.
