Role of cellular immunity in protection against Trypanosoma cruzi in mice
The importance of antibodies in the maintenance of immunity against Trypanosoma cruzi in mice is emphasized by the failure of either immunization or transfer of immune T cells to afford B cell suppressed mice complete protection against a lethal infection. Both procedures did, however, significantly prolong survival indicating a contributory role for T cells other than simply as helper cells in antibody production. The complete protection afforded intact mice following transfer of immune T cells can be attributed to a significant T cell-mediated augmentation of IgG antibody production.
