Abstract
The frequency of gamma-interferon (IFN-γ) secreting cells was examined in tonsillar cell suspensions. Comparisons were made between tonsils from orally and/or parenterally immunized individuals and non-immunized controls, and between infected and clinically healthy tonsils. Our results show that the tonsils are the site of pronounced T-lymphocyte (and possibly natural killer cell) activation, irrespective of intentional immunization or clinical status. In addition, this study suggests that interleukin-1 is required not only as an inducer of IFN-γ synthesis, but also as a promoter of its secretion.
