In situ visualization of antigen-specific T cells in cryopreserved human tissues.
Tetrameric MHC/peptide complexes are important tools for analyzing antigen-specific T cells. The in situ use of tetrameric MHC/peptide complexes in viable tissue sections has several shortcomings: it does not allow the execution of multiple analyses on one single biopsy, the storage of the biopsies, and the co-staining of the tetramer-positive cells for various intracellular molecules. We have developed a novel approach using overnight pre-labeling of viable human tissues with MHC/peptide tetramers, followed by cryopreservation and labeling of the cryosections. The visualization of antigen-specific T cells, combined with detection of other membrane, cytoplasmic, or nuclear markers is now feasible.
