Abstract
The role of thymic stromal lymphopoietin (TSLP) in chronic infection is not well understood. We report an increased number of cluster of differentiation 8 (CD8+ T) cells and higher expression of TSLP in the tonsil tissues of patients with recurrent tonsillitis as compared to that in the tonsil tissues of patients with tonsillar hypertrophy. Stimulation of tonsil CD8+ T cells with TSLP in the recurrent tonsillitis group resulted in higher production of interferon gamma (IFN-γ) and increased cell proliferation when compared to that in the tonsillar hypertrophy group. These results suggest the possibility that recurrent infection of tonsils may enhance local CD8+ T cell proliferation and IFN-γ and TSLP production. Anti-TSLP antibodies, which are potential therapeutic agents in allergic diseases, could have beneficial effects in patients with recurrent tonsillitis.
