Bystander t cell activation
WebApr 7, 1997 · Bystander activation, i.e., activation of T cells specific for an antigen X during an immune response against antigen Y may occur during viral infections. However, the low frequency of bystander-activated T cells has rendered it difficult to define the mechanisms and possible in vivo relevance of this nonspecific activation. WebApr 12, 2024 · SKCM-CD8 + T cells showed higher activation than GBM-CD8 + T cells , irrespective of anatomical location (fig. S11, A to C). Proximity of CD4 + and CD8 + T cells to each (with <20-μm relative distance representing cell-to-cell contact range) increased markers of activation in SKCM-CD8 + T cells but not GBM-CD8 + T cells (Fig. 5H and
