Expression data of tonsills of chronic tonsillitis, and peri-tumoral tonsillar tissues and lymph nodes in oropharyngeal cancer

Secondary lymphoid organs (SLOs) serve as an interface between tumor cells and immune system as an initial site of antigen presentation which is critical for the development of an effective anti-tumor immune response. We used microarray to analyze the gene expression profile of tonsills from chronic tonsillitis, and peri-tumoral tonsillar tissues and lymph nodes of oropharyngeal cancer. We analyzed and compared the profiles of these organs.
