The Schlößer group at the Center for Molecular Medicine investigates translationally relevant mechanisms of immune evasion in solid cancers. Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous group of cancers arising from the mucosal epithelium of the oral cavity, pharynx, and larynx driven by the accumulation of somatic mutations or human papillomavirus (HPV) infection. The specific research project focuses on the role of impaired antigen presentation in primary resistance to immunotherapy in HNSCC.
