Additionally, another study reported an elevated presence of CD8+ T cells with PD‐1, T‐cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine‐based inhibitory motif domains (TIGHIT) and T cell immunoglobulin domain and mucin domain‐3 (Tim‐3) expression in BALF from NSCLC and other cancer patients with PD‐1/PD‐L1 inhibitor‐related interstitial lung disease (ILD), as opposed to other ILD types.101. This evidence concerns the gene CD8A and cancer.
