Abstract
Allogeneic haematopoietic stem cell transplantation (HSCT) after a reduced-intensity conditioning (RIC) regimen with fludarabine, melphalan and alemtuzmab is an effective therapy for haematological malignancies. Alemtuzumab, a monoclonal antibody against CD52, a glycosylphosphatidylinositol-anchor-bound surface protein on lymphocytes, depletes T cells to prevent graft-versus-host disease (GVHD). Despite this, acute and chronic GVHD (a/cGVHD) remain life-threatening complications after HSCT. The aim of the present study was to identify parameters to predict GVHD. In 69 patients after HSCT, T-cell subsets were functionally analysed. Reconstitution of CD52neg T cells and CD52neg regulatory T cells (Tregs) correlated with onset, severity and clinical course of aGVHD. Patients with aGVHD showed significantly lower levels of CD52pos T cells compared to patients with cGVHD or without GVHD (P < 0·001). Analysis of T-cell reconstitution revealed a percentage of <40% of CD52pos CD4pos T cells or CD52pos Tregs at day +50 as a risk factor for the development of aGVHD. In contrast, CD52neg Tregs showed significant decreased levels of glycoprotein A repetitions predominant (GARP; P < 0·001), glucocorticoid-induced TNFR-related protein (GITR; P < 0·001), chemokine receptor (CXCR3; P = 0·023), C-C chemokine receptor type 5 (CCR5; P = 0·004), but increased levels of immunoglobulin-like transcript 3 (ILT3; P = 0·001), as well as a reduced suppressive capacity. We conclude that reconstitution of CD52neg T cells and CD52neg Tregs is a risk factor for development of aGVHD.

Abstract
Regulatory T cells (Treg cells) represent a CD4+ T-cell lineage that plays a critical role in restraining immune responses to self and foreign antigens and associated inflammation. Due to the suppressive function of Treg cells, inhibition or ablation of these cells can be used to boost the immunity against malignant cells. On the other hand, augmenting the activity of Treg cells can be employed for the treatment of inflammatory or autoimmune diseases and allogeneic conflicts associated with transplantation. Graft-versus-host disease (GvHD) is a leading cause of morbidity and mortality after haematopoietic stem cell transplantation (HSCT). In this review, we describe basic biological properties of Treg cells and their role in GvHD. We focus on the application of adoptive transfer of Treg cells and the therapeutic modulation of their activity for the prevention and treatment of GvHD in pre-clinical models and in clinical settings. We also discuss the main obstacles to applying Treg cell-based therapies for GvHD in clinical practice.

Abstract
Lung transplantation has evolved into a life-saving therapy for select patients with end-stage lung diseases. However, long-term survival remains limited because of bronchiolitis obliterans syndrome (BOS). Soluble HLA-G, a mediator of adaptive immunity that modulates regulatory T cells and certain classes of effector T cells, may be a useful marker of survival free of BOS. We conducted a retrospective, single-center, pilot review of 38 lung transplant recipients who underwent collection of serum and bronchoalveolar lavage fluid 3, 6 and 12 months after transplantation, and compared soluble HLA-G concentrations in each to the presence of type A rejection and lymphocytic bronchiolitis in the first 12 months and to the presence of BOS at 24 months after transplantation. Lung soluble HLA-G concentrations were directly related to the presence of type A rejection but not to lymphocytic bronchiolitis. Our data demonstrate that soluble HLA-G concentrations in bronchoalveolar lavage but not in serum correlates with the number of acute rejection episodes in the first 12 months after lung transplantation, and thus may be a reactive marker of rejection.

Abstract
Graft versus host disease (GVHD) is the major complication of allogeneic hematopoietic stem cell transplantation. GVHD is characterized by an imbalance between the effector and regulatory arms of the immune system which results in the over production of inflammatory cytokines. Moreover, there is a persistent reduction in the number of regulatory T (Treg) cells which limits the ability of the immune system to re-calibrate this proinflammatory environment. Treg cells are comprised of both natural and induced populations which have unique ontological and developmental characteristics that impact how they function within the context of immune regulation. In this review, we summarize pre-clinical data derived from experimental murine models that have examined the role of both natural and induced Treg cells in the biology of GVHD. We also review the clinical studies which have begun to employ Treg cells as a form of adoptive cellular therapy for the prevention of GVHD in human transplant recipients.

Abstract
PURPOSE OF REVIEW Successful immune reconstitution is important for decreasing posthematopoietic cell transplant (post-HCT) infections, relapse, and secondary malignancy, without increasing graft-versus-host disease (GVHD). Here we review how different parts of the immune system recover, and the relationship between recovery and clinical outcomes. RECENT FINDINGS Innate immunity (e.g., neutrophils, natural killer cells) recovers within weeks, whereas adaptive immunity (B and T cells) recovers within months to years. This has been known for years; however, more recently, the pattern of recovery of additional immune cell subsets has been described. The role of these subsets in transplant complications like infections, GVHD and relapse is becoming increasingly recognized, as gleaned from studies of the association between subset counts or function and complications/outcomes, and from studies depleting or adoptively transferring various subsets. SUMMARY Lessons learned from observational studies on immune reconstitution are leading to new strategies to prevent or treat posttransplant infections. Additional knowledge is needed to develop effective strategies to prevent or treat relapse, second malignancies and GVHD.

Abstract
Regulatory T cells (Tregs) maintain transplantation tolerance and suppress graft-versus-host disease (GvHD) in humans. We monitored 17 subjects with acute GvHD to determine whether Treg frequency correlates with acute GvHD. We found the percent of CD4(+) CD25(-) CD69(+) Tregs decreases when acute GvHD develops and increases after acute GvHD is controlled. We next sequentially studied 50 subjects receiving conventional allotransplants. We show a high frequency and increased numbers of CD4(+) CD25(-) CD69(+) Tregs are associated with a reduced risk of acute GvHD. We also show that CD4(+) CD25(-) CD69(+) Treg numbers increase substantially early after allografts and that a low percent of CD4(+) CD25(-) CD69(+) Tregs is associated with an increased risk of acute GvHD. Reconstitution of Tregs early post-transplant is associated with less acute GvHD. These data imply that CD4(+) CD25(-) CD69(+) Tregs are a novel subset of regulatory T cells that may protect against acute GvHD after allotransplants.

Abstract
Regulatory T cells (T(regs) ) play a key role in the prevention of acute graft-versus-host disease (aGVHD). To investigate the association between T(reg) subsets and aGVHD, we prospectively analysed T cell subsets in the allografts of 35 patients undergoing myeloablative unmanipulated haematopoietic stem cell transplantation. Multivariate analysis found that patients infused with less than 0·29 × 10(6) /kg of CD4(+) CD25(high) CD45RA(+) CD62L(+) T cells during transplantation exhibited an increased incidence of II-IV aGVHD [hazard ratio (HR) = 0·000, 95% CI = 0·000-0·106, P = 0·013]. Next, we compared the reconstitution characteristics of T cell subsets between haploidentical haematopoietic stem cell transplantation (HSCT) and sibling HSCT by collecting peripheral blood samples at regular intervals (days 30, 60 and 90) after transplantation. No significant differences were observed in the reconstitution of conventional T cells between haploidentical HSCT and sibling identical HSCT. However, total counts of recovered naiveT(regs) and CD62L(+) naive T(regs) from haploidentical HSCT were significantly lower compared to sibling identical HSCT; P-values were 0·045 and 0·021, respectively. Although total counts of conventional T cells in aGVHD patients reached similar levels compared to non-aGVHD patients before day 60 post-HSCT, total counts of naive T(regs) and CD62L(+) naive T(regs) in aGVHD patients did not reach similar levels to non-aGVHD patients until 90 days post-HSCT. Taken together, our findings demonstrate that a large population of CD62L(+) naive T(regs) in allografts reduces the incidence of aGVHD. Further, development of aGVHD is related closely to the delayed reconstitution of the naive T(reg) population.

Abstract
Previous studies suggest regulatory T cells (Tregs) inhibit graft-versus-host disease (GVHD) in mouse and human hematopoietic cell transplant (HCT) recipients. As the gastrointestinal tract represents one of the most common and severe sites of GVHD-related tissue damage, we sought to determine whether a deficit in circulating or gastric mucosal Treg numbers correlates with the clinical onset of gastric GVHD. We used the marker FOXP3 to quantify Tregs in blood and in gastric antral biopsies in a cohort of 60 allogeneic HCT recipients undergoing endoscopy at a single center to evaluate symptoms suspicious for gastrointestinal GVHD. We show for the first time in the gastric mucosa and, contrary to existing reports, in the blood, that the percent of T cells expressing FOXP3 is at least as high in the presence as in the absence of GVHD involving the upper gut. There was no correlation of Treg frequency with the histologic or clinical severity of gastrointestinal GVHD. We conclude that Treg depletion is not a central feature in the pathogenesis of gastric GVHD in humans.

Abstract
The relationship between regulatory T cells (Tregs) and acute graft-versus-host disease (aGVHD) in clinical allogeneic bone marrow transplantation (BMT) recipients is not well established. We conducted a prospective analysis of peripheral blood Tregs as determined by the frequency of CD4(+)CD25(hi)FOXP3(+) lymphocytes in 215 BMT patients. Autologous BMT patients (N = 90) and allogeneic BMT patients without GVHD (N = 65) had similar Treg frequencies, whereas allogeneic patients with GVHD (N = 60) had Treg frequencies that were 40% less than those without GVHD. Treg frequencies decreased linearly with increasing grades of GVHD at onset, and correlated with eventual maximum grade of GVHD (P < .001). In addition, frequency of Tregs at onset of GVHD predicted the response to GVHD treatment (P = .003). Patients with Treg frequencies less than the median had higher nonrelapse mortality (NRM) than patients with Tregs greater than the median, but experienced equivalent relapse mortality, resulting in an inferior survival at 2 years (38% versus 63%, P = .03). Treg frequency may therefore have important prognostic value as a biomarker of aGVHD.
