LAG3 and nasopharyngeal carcinoma: Single-cell transcriptome analysis revealed three NK cell subsets, among which the tissue resident NK cell subset showed increased expressions of inhibitory receptors, including TIGIT, LAG3 and TIM-3 (HAVCR2) [14, 15], and we proved our conclusion in another single-cell dataset (GSE150825) including NK-NPC and NLH.
