Résumé :

One of the challenges for immunomonitoring in clinical trials is to detect an antigen specific T cell-mediated immune response. In an attempt to define the most suitable assay, tetanus toxoid was used to compare the capacity of 4 different methods to detect cytokine responses, before and after recall vaccination, in peripheral blood mononuclear cells (PBMC) of 14 healthy volunteers. ELISA, ELISPOT, intracytoplasmic detection and real-time RT-PCR were chosen to measure IFN-gamma production before and after vaccination. As far as the detection of memory T cell status (before vaccination) was concerned, we found that ELISPOT was the most sensitive method to discriminate TT-induced from spontaneous responses. On the other hand, intracytoplasmic cytokine detection was the most efficient method to detect the restimulating effect of TT vaccination.
