title: Lymphokine (interleukin 2) secretion as a measure of T cell recognition of parasite antigens.
abstract: The secretion of the lymphokine, Interleukin 2 (IL2), from cells obtained from the lymph nodes of mice infected by the murine nematode, Nematospiroides dubius, is used an indication of T cell recognition of parasite antigens. It is demonstrated that IL2 secretion is T cell-dependent and occurs only when the lymph node cells are cultivated in the presence of at least 5 micrograms/ml of a parasite antigen preparation. The presence of adherent peritoneal exudate cells from uninfected mice in the cultures is an essential requirement for lymphokine release. This system can be used to quantitate T cell recognition of parasite antigens and to study T cell/antigen-presenting-cell interactions involved in the immune response to parasite infection.
