15 صفحه اولHarnessing Dendritic Cells for Tumor Antigen Presentation
Dendritic cells (DC) are professional antigen presenting cells that are crucial for the induction of anti-tumor T cell responses. As a consequence, research has focused on the harnessing of DCs for therapeutic interventions. Although current strategies employing ex vivo-generated and tumor-antigen loaded DCs have been proven feasible, there are still many obstacles to overcome in order to impro...
متن کاملComplementary Role of CD4+ T Cells and Secondary Lymphoid Tissues for Cross-presentation of Tumor Antigen to CD8+ T Cells
MHC class I-restricted tumor antigens can be presented to CD8+ T cells by two distinct pathways: via direct and indirect presentation. The relative contribution of these two pathways toward the initial activation of tumor antigen-specific CD8+ T cells and their subsequent tumor rejection is still vigorously debated. Using a tumor model able to dissect the relative contributions of direct and in...
متن کاملA novel role for granzymes in anti-tumor immunity
The cytotoxic properties of granzymes are well established, though recent publications suggest additional roles for granzymes in immunity. We demonstrated that granzymes can act as regulators of cross-presentation by dendritic cells by inducing critical "eat-me" signals on the dying tumor cell, resulting in efficient phagocytosis of cell-associated tumor antigen.
متن کاملCorrection: Critical role for Sec22b-dependent antigen cross-presentation in antitumor immunity
The authors regret that in the original version of their paper, they mistakenly used the phrase OVA-expressing cells instead of OVA-secreting cells in parts of the text and cited reference Boissonnas et al. (2007. http://dx.doi.org/10.1084/jem.20061890) instead of Zeelenberg et al. (2008. http://dx.doi.org/10.1158/0008-5472.CAN-07-3163) and Sedlik et al. (2014. http://dx.doi.org/10.3402/jev.v3....
