Spleens from Lewis X BN F1 hybrid rats were directly anastamosed to the circulation of parental strain Lewis rats by a microvascular technique; no immunosuppressive drugs were given. Donor spleens enlarged massively during the first month after implantation, then grew gradually smaller over succeeding months without compromising their blood supply. Renal allografts were placed into bilaterally nephrectomised recipients that had already borne a splenic allograft for three months. The grafts functioned perfectly and showed no signs of rejection five months later. Donor LBN skin allografts transplanted to these animals showed markedly prolonged survival while third-party BUF rat skin allografts were rejected in first-set fashion. High titres of anti-LBN haemagglutinating antibody could be detected in the circulation of spleen-grafted animals during the first month; the titres fell to zero by the fourth month. Cellular reactivity of recipient cells against LBN antigens measured by the popliteal node GVH assay fell to minimal levels by the third month. These data indicate that the immune response to allografted tissues may be specifically and markedly suppressed in adult animals by continued presence of a donor-strain spleen.

In spite of intensive endeavours, attempts to identify nephritogenic antigens in cases of immune complex glomerulonephritis have not yielded convincing results. Cationic antigens can have high affinity for the glomerular basement membrane and are prime candidates as nephritogens. They can be expected to play a role in post-infectious and in autoimmune glomerular disease. Histones show great promise in the latter case: we are able to demonstrate (1) a high affinity for the glomerular basement membrane and (2) their ability to promote glomerular deposition of anionic antigens as an additional target. Histones were detectable in glomerular deposits in two murine models of glomerulonephritis: the spontaneous lupus-like disease of NZB/W F1 mice and in graft-versus-host disease. We propose that histones may be responsible for the induction of glomerulonephritis in lupus-like syndromes, as well as other types of autoimmune renal disease. As an analogue, histone-like proteins from micro-organisms may also be responsible for glomerular disease in post-infectious nephritis.

More than 30 years have passed since the first clinical application of allogeneic bone marrow transplantation to treat hematological diseases. In recent years, the availability of peripheral blood and cord blood as additional sources of stem cells other than bone marrow has expanded the applicability of hematopoietic stem cell transplantation. In addition to differences in stem cell content, immune cells in the grafts from the three sources are different in quality and quantity. As a consequence, transplants from different sources have different kinetics of hematological recovery. Stem cell sources also influence risks for developing graft-versus-host disease. In this paper, we review recently reported results of thus diversified allogeneic hematopoietic, stem cell transplantation.

Molecular remissions were observed in some relapsed post allogeneic transplant chronic myeloid leukemia (CML) patients who received donor peripheral blood lymphocyte infusions (DLI). This was indirect evidence of immune-mediated tumor cell killing, and the process was termed graft-versus-leukemia (GVL). Mechanisms were hypothesized to be direct T cell mediated cell lysis or augmented programmed cell death. These observations formed the basis for exploring the role of DLI first in relapsed allogeneic transplant patients with other hematologic malignancies, then as prophylaxis for patients at high risk for relapse and then as adjunctive therapy for transplant strategies utilizing non-myeloablative conditioning regimens. Multiple clinical trials are underway to define dose, schedule, clinical and molecular response and laboratory assays to distinguish lymphocyte subsets mediating GVL and those responsible for graft-versus-host disease (GVHD) toxicity. This review outlines some of the donor/patient and therapy variables involved and some principles of mononuclear cell collection for cellular immunotherapy.

Reduced-intensity hematopoietic stem cell transplantation (RIST) is a new approach of stem cell transplantation, which has shown promising features as reported in multiple phase I and II studies. Elderly patients, who are not eligible for conventional myeloablative hematopoietic stem cell transplantation (HSCT), are now treatable with RIST. It has also reduced regimen-related toxicity and provided better prognosis in short-term follow-up than that of conventional HSCT. Favorable results have been reported particularly in hematological malignancies, such as chronic myelocytic leukemia and malignant lymphoma. Among solid tumors, metastatic renal cell carcinoma was found to respond well to RIST. Clinical studies are currently being conducted to evaluate the efficacy of RIST in other types of solid tumors. However, the mechanism of graft-versus-host disease and graft-versus-tumor remains unclear. More knowledge on the mechanism is crucial to enhance antitumor effect and to further improve the prognosis.

Extracorporeal photochemotherapy (ECP) has been progressively introduced into the treatment of both acute and chronic graft-versus-host disease (cGvHD) over the last decade. Nevertheless, its mechanisms of action, as well as the optimal treatment schedule, have not yet been defined. We retrospectively analyzed 25 patients with cGvHD unresponsive to conventional treatments who underwent ECP from 1997 until 2005. The impact of various factors (such as treated and infused nucleated cells, time from transplantation and cGvHD onset, and time from cGvHD and ECP treatment) on the probability of no response to ECP was therefore investigated. A positive response to ECP was achieved in 80% of the patients, after a median of 19 ECP treatments (with a range of 8-38). Eighteen out of the 20 patients responsive to the treatment maintained their response for a median of 30 months. We mainly focused on clinical response and yield composition. The analysis on mononuclear cell (MNC) dose suggested that an increase of MNC dose/kg b.w. (body weight) induced a decrease in the odds of treatment failure, and that, if the MNC dose infused was at least 100 x 10(6)/kg b.w. per ECP treatment, a more positive and longer-lasting response was achieved. Moreover, the mean dose of treated and infused monocytes x 10(6)/kg b.w./ECP did not account for a clear dose-related effect. These findings may eventually result in a more patient-tailored approach to ECP. Prospective multicenter trials should be designed to investigate the real impact of MNC dose on ECP responsiveness.

Disturbed kidney function is a common occurrence after bone-marrow transplantation. Sepsis, nephrotoxic medications, thrombotic microangiopathy and injury related to haemodynamic alterations are frequently accountable. Recently, attention has been given to immune-mediated glomerular damage, related to graft-versus-host disease. Herein we describe the fatal course of a nephrotic syndrome complicating allogeneic stem cell transplantation in a young woman with long-standing paroxysmal nocturnal haemoglobinuria. A post-mortem kidney biopsy revealed amyloidosis of the AA type. Physicians should be aware of the possibility that infections and inflammation accompanying the post-transplantation period may rarely promote the development of systemic amyloidosis or exacerbate silent pre-existing disease.

We report the development of IgA nephropathy (IgAN) following full myeloablative allogeneic hematopoietic cell transplantation in two patients with human leukocyte antigen (HLA) matched sibling donors, unrelated to active or chronic graft-versus-host disease. Both recipients had elevated urinary levels of galactose-deficient IgA1, and one donor-recipient pair had elevated serum levels of galactose-deficient IgA1. We propose that IgAN developed after bone marrow transplantation due to a non-graft-versus-host-disease-related multi-hit process associated with glomerular deposition of galactose-deficient IgA1. These two cases provide unique insight into the kinetics of overproduction of galactose-deficient IgA1 and its glomerular deposition and consequential renal injury in IgAN.

From the 1980s, extracorporeal photochemotherapy (ECP) has been shown to be effective in a variety of pathological conditions such as erythrodermic cutaneous T-cell lymphoma, autoimmune diseases, solid organ allograft rejection and graft versus host disease. To date, ECP represents a non-aggressive immune modulatory therapy with a low spectrum of toxicity. ECP reduces the alloreactivity promoting the immune tolerance to self. At the same time, it allows the maintenance of immune response integrity of both naive and memory T-cells. However, the molecular mechanisms of action by which ECP exerts its therapeutic activity are still under investigation. Here, we review molecular mechanisms and clinical applications involved in ECP. The outcome of ECP is difficult due to the lack of reliable predictor factors for the selection of patients and their adequate follow-up. Since the study of such predictors is important, we also describe some biological markers that enable us to investigate the clinical management of the patients considered for the use of ECP.
