Abstract
Priming of recipients by DST induces long-term survival of mismatched allografts in adult rats. Despite these recipients developing inducible T regulatory cells able to transfer long-term graft survival to a secondary host, a state of chronic rejection is also observed. We revisited the molecular donor MHC targets of the cellular response in acute rejection and analyzed the cellular and humoral responses in recipients with long-term graft survival following transplantation. We found three immunodominant peptides, all derived from LEW.1W RT1.D(u) molecules to be involved in acute rejection of grafts from unmodified LEW.1A recipients. Although the direct pathway of allorecognition was reduced in DST-treated recipients, the early CD4+ indirect pathway response to dominant peptides was almost unimpaired. We also detected early and sustained antidonor class I and II antibody subtypes with diffuse C4d deposits on graft vessels. Finally, long-term accepted grafts displayed leukocyte infiltration, endarteritis and fibrosis, which evolved toward vascular narrowing at day 100. Altogether, these data suggest that the chronic graft lesions developed in long-term graft recipients are the result of progressive humoral injury associated with a persisting indirect T helper response. These features may represent a useful model for understanding and manipulating chronic active antibody-mediated rejection in human.

Abstract
Long-term survival is achieved in rat recipients by pre-graft donor-specific blood transfusion. We characterized the immune compartments in long-term survivors and analyzed them for capacity to transfer tolerance and protect against chronic rejection. Splenocytes and spleen T cells from treated recipients transferred long-term graft survival to 100% of secondary recipients. In contrast, blood transferred graft survival to only 50% of recipients whereas blood T cells had no effect. An unaltered TCR repertoire, an increase in suppressive CD4+CD25+ T cells, a decrease in antidonor T-cell proliferative response and normal perforin-granzyme levels were the hallmarks of the spleen T cells. Blood T cells were characterized by a strongly altered CD8+ repertoire, normal CD4+CD25+ T cell number with unchanged antidonor T-cell proliferative response, an activated T-cell phenotype and an increase in perforin-granzyme levels. However, following the transfer of blood or spleen cells into secondary recipients, all grafts displayed chronic rejection. These findings provide evidence that distinct compartments play critical roles in DST recipients. Regulatory cells do not accumulate in blood, which appears to be a reservoir for cytotoxic T cells. Spleen T cells, which display a regulatory-like profile and transfer graft survival, are not able to prevent chronic rejection.

Abstract
The structure and the dynamic organization of a mixed Langmuir film of glucose oxidase and stearylamine at the air-water interface have been studied. The film has been first characterized at the air-water interface by surface pressure/area isotherms. The dynamics of the mixed film was studied by following the evolution of the film area at a constant pressure and the evolution of the pressure at a constant area. After transfer of the films on solid substrates, the chemical composition of the mixed film has been quantified by UV-vis and IR spectroscopies. These characterizations were carried out in order to study the incorporation of glucose oxidase into the stearylamine film, and its influence on the structural evolution of the film. From these results, the dynamic organization of this mixed film may be described. For short times, glucose oxidase molecules interact with stearylamine molecules in solution or at the interface; these interactions would lead to the formation of a complex between stearylamine and glucose oxidase molecules. For long times (at least 3 h), a homogeneous mixed film constituted essentially of this complex is obtained at the air-water interface. A detailed analysis by atomic force microscopy allowed us to support this model and the existence of the glucose oxidase/stearylamine complex.

Abstract
The kinetics of the primary and secondary humoral responses to either encapsulated or surface-linked bovine serum albumin have been compared by measuring the production of specific total immunoglobulin, IgG and IgM at various times postimmunization. From our data it can be concluded that surface linkage is the best way to induce a rapid, intense and prolonged response which, in contrast to that induced by encapsulated BSA, is characterized by a low IgG/IgM ratio. The results are discussed in relation to the possible routes followed by the antigen depending on its mode of association with liposomes in the initiation of the humoral response. Our results suggest that liposomal vaccine may be designed to activate specific pathways of the immune network preferentially.
