چکیده انگلیسی
Most immuno-therapeutic approaches are based on tumor-associated antigens and many newly identified proteins have led to trials exploiting their possible therapeutic applicability. So far only limited information on the antigenic profile of head and neck squamous cell carcinomas (HNSCC) exists. Serological analysis of tumor antigens by recombinant cDNA expression cloning (SEREX) was used to identify the immunogenic patterns in our HNSCC patient collective. A cDNA expression library derived from a pharynx HNSCC case was screened with autologous and heterologous sera. Thirty-seven positive clones coding for 17 immunoreactive gene products, which elicited an in vivo tumor response, were found. Results were confirmed and extended by expression analysis using RT-PCR and in situ-hybridisation. The protein-sequence of five clones exists so far only hypothetically. Of all identified proteins only KIAA0530 has previously been associated with a HNSCC related immune response. All other proteins have not yet been described in a context with HNSCC antigenic patterns. Antibodies against a heat shock transcription factor 2 (HSF2) were found in 2 out of 10 sera from HNSCC patients. In summary, using the SEREX technique, we isolated 17 immunogenic antigens in HNSCC's and confirmed the clinical relevance of KIAA0530. Further analysis concerning their feasibility as target structures for an immunotherapy approach is currently conducted.
