Abstract Background The palatine tonsils have a pivotal role in immunological detection of airborne and ingested antigens like bacteria and viruses. They have recently been demonstrated to express Tolllike receptors TLRs known to recognize molecular structures on such microbes and activate innate immune responses. Their activation might also provide a link between innate and adaptive immunity. In the present study the expression profile of TLR1-TLR10 was characterized in human tonsil T cells focusing on differences between subsets of CD4 T helper Th cells and CD8 cytotoxic T lymphocytes CTL . The study was also designed to compare the TLR expression in T cells from patients with recurrent tonsillitis and tonsillar hyperplasia. Methods Tonsils were obtained from children undergoing tonsillectomy and classified according to the clinical diagnoses and the outcome of tonsillar core culture tests. Two groups were defined recurrently .
