Abstract

We present and analyze a model for the interaction of naive T cells with antigen presenting cells (APCs) that results in T-cell activation. We use this model to examine delayed type hypersensitivity (DTH) reactions. We show that responses can be of two types; either the antigen is completely eliminated or the immune system fails to eliminate the antigen and chronic infection results. Both outcomes are characteristic of diseases in which delayed type hypersensitivity is the primary defense mechanism. We compare the effectiveness of two types of APCs macrophages and dendritic cells, in the generation of DTH responses. We conclude that dendritic cells are more suited to the task of stimulating naive T cells than are macrophages, as has recently been argued by Steinman and coworkers.

Death ligand TRAIL induces no apoptosis but inhibits activation of human (auto)antigen-specific T cells.

TNF-related apoptosis-inducing ligand (TRAIL), a member of the TNF superfamily, induces apoptosis in susceptible cells, which can be both malignant and nontransformed. Despite homologies among the death ligands, there are great differences between the TRAIL system on the one hand and the TNF and CD95 systems on the other hand. In particular, TRAIL-induced apoptosis differs between rodents and man. Studies on animal models of autoimmune diseases suggested an influence of TRAIL on T cell growth and effector functions. Because we previously demonstrated that TRAIL does not induce apoptosis in human (auto)antigen-specific T cells, we now asked whether TRAIL exhibits other immunoregulatory properties in these cells. Active TRAIL inhibited calcium influx through store-operated calcium release-activated calcium channels, IFN-gamma/IL-4 production, and proliferation. These effects were independent of APC, Ag specificity, and Th differentiation, and no differences were detected between healthy donors and multiple sclerosis patients. TRAIL affected neither the expression of the cell cycling inhibitor p27(Kip1) nor the capacity of T cells to produce IL-2 upon Ag rechallenge, indicating that signaling via TRAIL receptor does not induce T cell anergy. Instead, the TRAIL-induced hypoproliferation could be attributed to the down-regulation of the cyclin-dependent kinase 4, indicating a G(1) arrest of the cell cycle. Thus, although it does not contribute to mechanisms of peripheral T cell tolerance such as clonal anergy or deletion by apoptosis, TRAIL can directly inhibit activation of human T cells via blockade of calcium influx.

Dendritic cells cross-presenting viral antigens derived from autologous cells as a sensitive tool for visualization of human cytomegalovirus-reactive CD8+ T cells.

BACKGROUND: CD8+ T lymphocytes are essential to contain viral infections, such as human cytomegalovirus (HCMV). To visualize these clinically important effector cells, we used dendritic cells (DC), which efficiently present exogenous antigens by MHC class I molecules (cross-presentation). METHODS AND RESULTS: Immature DC were fed with apoptotic debris derived from autologous HCMV-infected macrophages. After maturation, the antigen-loaded DC were used to stimulate lymphocytes from the same donor. We could detect high numbers of interferon-gamma producing CD8+ T cells in HCMV-seropositive but not in HCMV-seronegative healthy individuals and in only one of five HCMV-seropositive immunosuppressed patients. In contrast, autologous DC infected with live HCMV virions stimulated antiviral CD8+ T lymphocytes to a lesser extent. CONCLUSION: We suggest that DC cross-presenting HCMV antigens derived from autologous macrophages could serve as a valuable tool to monitor and possibly enhance the antiviral T-cell response in patients after transplantation.

Focal localization of placental protein 14 toward sites of TCR engagement.

TCR signal transduction is amplified by the dynamic accumulation of accessory molecules at APC-T cell contact sites, along with the simultaneous exclusion from these sites of negative regulators, such as certain tyrosine phosphatases and large glycosylated proteins. However, given the general nature of the cytoskeleton-driven clustering mechanism underlying molecular segregation events at the APC-T cell interaction site, the possibility exists that negative regulators might similarly be segregated at these sites. Using fluorescence microscopy, we have demonstrated that placental protein 14 (PP14), a direct T cell inhibitor, focuses toward APC-T cell contact sites in conjunction with conjugate formation. We have further established that the function of PP14 is dependent upon its localization to the sites of TCR triggering, where it negatively regulates T cell activation. Thus, PP14 provides an example of a soluble negative T cell regulator whose inhibitory activity is linked to modulation of the APC-T cell contact site, thereby hindering early events triggered by the TCR.
