Next, using the ImmLnc web tool, we analyzed the correlation between these 99 lncRNAs and immune cell infiltration (mainly CD8+ T cells, dendritic cells, neutrophils, CD4+ T cells, B cells, and macrophages) in the ESCC TME (Additional file 1: P10–11), and 11 lncRNAs associated with TAM infiltration were identified (Additional file 1: P12). This evidence concerns the gene CD4 and esophageal squamous cell carcinoma.
