WebIn these data from the 1994 immunology class, spleen cells were stained for MHC class II (green) and CD4 (red). No cell should express both markers, but the dots in region 3 (R3) appear to be double-stainers. These "impossible" cells were an artifact due to clumping (red cells stuck to green cells, appearing as 'double-stained cells'). WebDec 9, 2024 · T cells use their T-cell receptors (TCRs) to discriminate between lower-affinity self and higher-affinity foreign peptide major-histocompatibility-complexes (pMHCs) based on the TCR/pMHC off-rate. It is now appreciated that T cells generate mechanical forces during this process but how force impacts the TCR/pMHC off-rate remains debated.
