Splet05. maj 2024 · These results suggest a defect at the level of effector T cell trafficking into non-T cell-inflamed tumors. Together, these data indicate that, whereas β-catenin-negative tumors allow effector T cell entry and dynamic cell contact with antigen-expressing tumor cells ultimately leading to tumor cell killing, β-catenin-positive tumors fail to ... SpletThe process of T-cell trafficking is highly dynamic, involving a series of distinct processes, which include rolling, adhesion, extravasation, and chemotaxis. Traf ficking of T cells to …

SpletThe accumulation of T cells is associated with a better prognosis in pancreatic cancer. However, the immunosuppressive tumor microenvironment, largely composed by cancer-associated fibroblasts (CAFs), can prevent T cells from reaching the tumor nests. We examined how human CAFs modulated chemokine receptors known to be associated … SpletTo directly investigate the in vivo trafficking of T cells into and out of tumors, here we have exploited photoactivatable Kaede transgenic mice to enable specific labeling of tumor … Splet16. feb. 2012 · Methodology/Principal Findings. High and low avidity CD8 + T cell receptor (TCR) transgenic mice specific for the breast cancer antigen HER-2/neu (neu) were developed to provide a purified source of naïve, tumor-specific T cells that can be used to study tolerance mechanisms.
