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.

ABSTRACT:

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 role of Siglec-10 in the specific immune suppressive tumor microenvironment remains largely unknown.

Methods

Immunohistochemical assays were employed to investigate the correlation of the expressions of Siglec-10 and Siglec-15 with the clinicopathological features as well as the prognosis of immunotherapy in patients with HNSCC. The Gene Expression Omnibus datasets were used to identify the upstream transcriptional regulators of SIGLEC10 in tumor-associated macrophages (TAMs) and the downstream biological functions it media
