RESUMO

Most techniques that identify antigen-specific T cells are dependent on the response of these cells to the relevant antigen in culture. Soluble multimers of MHC molecules, when occupied with the same peptide, will bind selectively to T cells specific for that MHC/peptide complex. Techniques to produce fluorescent MHC class II/peptide multimers have recently been developed. These reagents provide a method to facilitate detection and isolation of antigen-specific CD4+ T cells and they represent a new research tool to study these cells in patients with immune-mediated diseases.
