IL-4-STAT6-induced high Siglec-G/10 expression aggravates the severe immune suppressive tumor microenvironment and impedes the efficacy of immunotherapy in head and neck squamous cell carcinoma
Background
Immune checkpoint blockade therapy has shown limited efficacy in head and neck squamous cell carcinoma (HNSCC). Sialic acid binding immunoglobulin-like lectin (Siglec)-15 has been identified as a novel immune evasion biomarker, while the ro…
