Article Abstract
Head and neck squamous carcinoma (HNSC) poses a major threat to human life. The role of human papillomavirus (HPV) infection in the initiation and progression of HNSC is becoming more widely accepted. HPV-positive (HPV+) HNSC has shown unique responses to cancer therapies, which may be due to differences in immune cell infiltration. It is critical to determine how the immune responses to HPV in HNSC are regulated. Transcriptome data of HNSC from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) database were analyzed. Then, the CIBERSORT algorithm was used to calculate immune cell infiltration in HNSC. FDCSP expression level was detected by qPCR in the HNSC tissues collected from the Nanfang Hospital. Follicular dendritic cell secreted protein (FDCSP) was highly expressed in HPV+ HNSC, and higher expression of FDSCP was associated with a favorable prognosis. In HPV+ HNSC samples, FDCSP significantly increased the proportion of T follicular helper cells (TFHs). FDCSP expression was also found to be associated with TP53 mutation status in HPV+ HNSC. The function of FDCSP was intimately connected to chemokine pathways, particularly with the C-X-C motif chemokine ligand 13 (CXCL13). We verified that the high expression of FDCSP in HPV+ HNSC and higher FDCSP is closely related to prognosis in HNSC samples we collected by qPCR. Collectively, these findings may provide fresh evidence that FDCSP is a potential chemokine-associated prognostic biomarker in HPV+ HNSC.

Background: The role of alternative splicing events (ASEs) in immune evasion and prognosis in head and neck squamous cell carcinoma (HNSC) is not well characterized.
Methods: Using The Cancer Genome Atlas data, we identified ASEs (using our novel algorithm OutSplice) and characterized associations between splice burden, immune infiltration (quantified by xCell) and prognosis with multivariable logistic regression and survival models.
Results: HSNC tumors with low splice burden and high immune infiltration had significantly better prognosis than tumors with high splice burden and low immune infiltration when controlling for age, pathologic stage, HPV status, and tumor mutational burden (hazard ratio = 0.
Mature tertiary lymphoid structures linked to HPV status and anti-PD-1 based chemoimmunotherapy response in head and neck squamous cell carcinoma.

Mature tertiary lymphoid structures (TLSs) are immune aggregates associated with immune checkpoint blockade (ICB) responses in various cancers, yet their role in chemoimmunotherapy response in head and neck squamous cell carcinoma (HNSCC) remains unclear. By analyzing TCGA-HNSC transcriptomic data and pathology slides, we identified an immune subtype enriched in TLSs, predominantly in HPV-positive tumors, which correlated with favorable immunotherapy response. Single-cell and spatial transcriptomics further revealed distinct TLS compositions, with mature TLSs enriched in germinal center B cells, follicular helper T cells, and resident memory CD8 T cells, while immature TLSs contained FCRL4+ B cells and peripheral helper T cells.

The metastasis of human papilloma virus (HPV)-negative head and neck squamous cell carcinoma (HNSC) is associated with poor prognosis, yet the regulatory mechanisms remain unclear. In this study, we developed a metastasis prediction model using the transcriptomes of 333 HPV-negative HNSC tumor samples, representing one of the largest HPV-negative HNSC sample sets to date. Our model, which leverages miRNA-centered regulatory networks extended by regulome data, showed superior predictive performance with an AUC of 0.

Background: Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous malignancy with poor prognosis. Dysregulation of E2F transcription factors (E2Fs), which control cell proliferation and apoptosis, is implicated in HNSCC pathogenesis. This study explores HNSCC molecular heterogeneity via E2Fs expression, identifies distinct subtypes, and develops a prognostic model that integrates gene expression, immune infiltration, and drug sensitivity.
