Murine in vivo CD8+ T Cell Killing Assay.
Antigen-specific killing ability of effector CD8+ T cells is critical for protective immunity against infection. Here, we describe in vivo cytotoxic T cell assay to examine effector function of antigen-specific CD8+ T cells. Mice infected with Listeria monocytogenes (L. monocytogenes) expressing chicken ovalbumin as a model antigen mount ovalbumin-specific CD8+ T cell responses. Effector CD8+ T...
متن کاملEstimating in vivo death rates of targets due to CD8 T-cell-mediated killing.
Despite recent advances in immunology, several key parameters determining virus dynamics in infected hosts remain largely unknown. For example, the rate at which specific effector and memory CD8 T cells clear virus-infected cells in vivo is hardly known for any viral infection. We propose a framework to quantify T-cell-mediated killing of infected or peptide-pulsed target cells using the widely...
متن کاملCD8+ T-cell-mediated killing of donor dendritic cells prevents alloreactive T helper type-2 responses in vivo.
Accumulating evidence indicates that, in absence of CD8+ T-cell activation, CD4+ T-cell-mediated allograft rejection is associated with a dominant Th2-cell response and eosinophil infiltrates. In this study, we analyzed the mechanisms by which CD8+ T cells regulate alloreactive CD4+ T-cell priming and differentiation into interleukin 4 (IL-4)-producing cells. We showed that interferon gamma (IF...
متن کاملMurine plasmacytoid dendritic cells induce effector/memory CD8+ T-cell responses in vivo after viral stimulation.
Like their human counterparts, mouse plasmacytoid dendritic cells (pDCs) play a central role in innate immunity against viral infections, but their capacity to prime T cells in vivo remains unknown. We show here that virus-activated pDCs differentiate into antigen-presenting cells able to induce effector/memory CD8(+) T-cell responses in vivo against both epitopic peptides and endogenous antige...
متن کاملHyperglycaemia does not affect antigen-specific activation and cytolytic killing by CD8+ T cells in vivo
Metabolism is of central importance for T cell survival and differentiation. It is well known that T cells cannot function in the absence of glucose, but it is less clear how they respond to excessive levels of glucose. In the present study, we investigated how increasing levels of glucose affect T-cell-mediated immune responses. We examined the effects of increased levels of glucose on CD8+ T-...
