dc.description.abstract | Treatment of head and neck squamous cell carcinoma (HNSCC) remains a challenge despite advanced therapies. Epidermal growth factor receptor (EGFR) and transforming growth factor β (TGFβ) negatively impact immune responses in HNSCC. This study explores the impact of EGFR inhibitors (lapatinib, erlotinib) on immune-related molecules and HNSCC immunogenicity. Inhibitors increased HLA-ABC expression and reduced programmed cell death ligand-1 (PD-L1) in HNSCC cell lines. EGFR phosphorylation and downstream proteins AKT and ERK were reduced in certain cell lines. EGFR inhibitor treatment elevated TGFβ-related mRNA levels, potentially explaining AKT and ERK activation. Tyrosine kinase inhibitor (TKI) treatment modulated chemokines and immune cell infiltration in HNSCC patient tissue samples. Altered HLA-ABC and PD-L1 expression suggest combining TKIs with immunotherapy may enhance outcomes for HNSCC patients. | eng |
dc.description.abstract | Die Behandlung von Kopf-Hals-Plattenepithelkarzinomen (HNSCC) bleibt trotz fortschrittlicher Therapieansätze eine Herausforderung. EGFR- und TGFβ-Signalwege beeinträchtigen negativ die Immunantworten bei HNSCC. Diese Studie untersucht die Auswirkungen von EGFR-Inhibitoren (Lapatinib, Erlotinib) auf immunrelevante Moleküle und die Immunogenität von HNSCC. Inhibitoren erhöhten HLA-ABC-Expression und reduzierten PD-L1 in HNSCC-Zelllinien. EGFR-Phosphorylierung und Proteine AKT und ERK wurden in bestimmten Zelllinien vermindert. EGFR-Inhibitorbehandlung erhöhte TGFβ-mRNA-Levels, was möglicherweise AKT- und ERK-Aktivierung erklärt. Tyrosinkinase-Inhibitorbehandlung modulierte Chemokine und Immunzellen-Infiltration in HNSCC-Patientengewebe. Veränderte HLA-ABC- und PD-L1-Expression deutet darauf hin, dass TKIs in Kombination mit Immuntherapie die Ergebnisse für HNSCC-Patienten verbessern könnten. | ger |
