TREM1 and lung adenocarcinoma: The heat maps illustrated that TREM1 expression was strongly associated with immunosuppressive genes (Figure 8A), chemokines (Figure 8B), chemokine receptors (Figure 8C) and MHC genes (Figure 8D) across most tumor types, except lung adenocarcinoma (LUAD), acute myeloid leukemia (LAML), head and neck squamous cell carcinoma (HNSC), cervical squamous cell carcinoma as well as endocervical adenocarcinoma (CESC).
