AbstractThe application of allogeneic stem cell transplantation (alloSCT) is limited by graft-versus-host disease (GVHD). GVHD can be divided into acute and chronic forms that likely have different requirements for initiation and pathogenesis mechanisms. In prior studies we demonstrated that residual host antigen-presenting cells (APCs) were required to initiate acute GVHD (aGVHD) mediated by CD8 T cells. In contrast, here we demonstrate that either donor or host APCs can initiate CD4-mediated GVHD in a model that has features of chronic GVHD (cGVHD). Both donor and host APCs must provide CD80/86-dependent costimulation to elicit maximal cGVHD, and there is no GVHD when both donor and host lack CD80/86. Finally, we were surprised to find that, although either donor or host APCs are sufficient to stimulate skin cGVHD, donor APCs play a dominant role in intestinal cGVHD. Both CD40 and CD80/86 are critical for donor APC function in intestinal cGVHD, but only CD80/86 is required for skin cGVHD. Thus, there are target-tissue–specific differences in APC requirements. These results identify differences in APC requirements between CD8-mediated aGVHD and CD4-mediated cGVHD. They further highlight donor APCs as additional targets for GVHD therapy.

Antigen Presenting

After allogeneic blood or bone marrow transplantation, donor T cells interact with a distorted antigen-presenting cell (APC) environment in which some, but not all, host APCs are replaced by APCs from the donor. Significantly, host APCs are required for the priming of acute graft-versus-host disease (GVHD). Donor APCs play a lesser role in the induction of acute GVHD despite their predicted capacity to cross-present host antigens. In contrast, donor APCs may play a role in perpetuating the tissue injury observed in chronic GVHD. Host APCs are also required for maximal graft-versus-leukemia responses. Recent studies have suggested potential strategies by which the continued presence of host APCs can be exploited to prime strong donor immunity to tumors without the induction of GVHD.

Antigen Presenting

Chronic graft-versus-host disease (cGVHD) is one of the most common reasons of late non-relapse morbidity and mortality of patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT). While acute GVHD is considered driven by a pathogenic T cell dominant mechanism, the pathogenesis of cGVHD is much complicated and involves participation of a variety of immune cells other than pathogenic T cells. Existing studies have revealed that antigen presenting cells (APCs) play crucial roles in the pathophysiology of cGVHD. APCs could not only present auto- and alloantigens to prime and activate pathogenic T cells, but also directly mediate the pathogenesis of cGVHD via multiple mechanisms including infiltration into tissues/organs, production of inflammatory cytokines as well as auto- and alloantibodies. The studies of this field have led to several therapies targeting different APCs with promising results. This review will focus on the important roles of APCs and their contributions in the pathophysiology of cGVHD after allo-HSCT.

Graft versus host disease is one of the main complications of Hematopoietic stem cell, in­volving about 50% to 80% of the patients. Acute GVHD clinical manifestations and therapy is discussed, as well as new NIH criteria for the diagnosis and classification of chronic GVHD. Therapy for both refractory chronic and acute GVHD is an important field of discussion once there is no superiority for the majority of the agents after primary therapy has failed. Hence, this review is meant to be a useful tool of consultation for clinicians who are dealing with this complex complication.

Graft Versus Host

Graft versus host disease (GVHD) pathophysiology is a complex interplay between cells that comprise the adaptive and innate arms of the immune system. Effective prophylactic strategies are therefore contingent upon approaches that address contributions from both immune cell compartments. In the current study, we examined the role of the type 2 cannabinoid receptor (CB2R) which is expressed on nearly all immune cells and demonstrated that absence of the CB2R on donor CD4+ or CD8+ T cells, or administration of a selective CB2R pharmacological antagonist, exacerbated acute GVHD lethality. This was accompanied primarily by the expansion of proinflammatory CD8+ T cells indicating that constitutive CB2R expression on T cells preferentially regulated CD8+ T cell alloreactivity. Using a novel CB2R-EGFP reporter mouse, we observed significant loss of CB2R expression on T cells, but not macrophages, during acute GVHD, indicative of differential alterations in receptor expression under inflammatory conditions. Therapeutic targeting of the CB2R with the agonists, tetrahydrocannabinol (THC) and JWH-133, revealed that only THC mitigated lethal T cell-mediated acute GVHD. Conversely, only JWH-133 was effective in a sclerodermatous chronic GVHD model where macrophages contribute to disease biology. In vitro, both THC and JWH-133 induced arrestin recruitment and ERK phosphorylation via CB2R, but THC had no effect on CB2R-mediated inhibition of adenylyl cyclase. These studies demonstrate that the CB2R plays a critical role in the regulation of GVHD and suggest that effective therapeutic targeting is dependent upon agonist signaling characteristics and receptor selectivity in conjunction with the composition of pathogenic immune effector cells.

Abstract To assess the influence of graft-versus-host disease (GVHD) on recurrent leukemia and survival after allogeneic marrow transplantation, we studied 1,202 patients with acute nonlymphocytic leukemia (ANL), acute lymphocytic leukemia (ALL), and chronic myelogenous leukemia (CML) given unmodified marrow grafts from HLA- identical siblings. Proportional hazards regression models using acute GVHD and chronic GVHD as time-dependent covariates demonstrated a significant association of GVHD with a decreased relative risk (RR, 0.33 to 0.42) of relapse in patients with ANL, ALL, and CML transplanted in advanced disease. Among patients developing either acute or chronic GVHD, treatment failure (that is, mortality or relapse) was decreased in patients with ALL transplanted in relapse (RR = 0.70, P less than .033) and CML in blast crisis (RR = 0.37, P less than .009). This effect was independent of age, sex, preparative regimen, GVHD prophylaxis, or length of follow-up. Five-year actuarial estimates were derived for the subset of 657 patients who survived in remission 150 days after transplant and were at risk for development of chronic GVHD. Among patients with ANL in first remission or CML in chronic phase, GVHD had an adverse effect on survival and no apparent influence on relapse. Among patients with ANL and ALL transplanted in relapse, the probability of relapse after day 150 was 74% without [corrected] GVHD, 45% with acute and chronic GVHD, 35% with [corrected] only acute GVHD, and 34% with only chronic GVHD (P less than .001). Actuarial survival in these four GVHD groups was 25%, 34%, 59%, and 62%, respectively (P less than .009). Among patients with CML in acceleration or blast crisis, the probability of relapse after day 150 was 65% without GVHD and 36% with acute and/or chronic GVHD (P less than .017). We conclude that acute and chronic GVHD were associated with a durable antileukemic effect and improved survival in patients transplanted in advanced stages of ALL and CML.

Abstract Introduction: The use of a calcineurin-inhibitor in combination with methotrexate is the current standard in the prophylaxis of graft versus host disease (GVHD). Everolimus is a newly developed m-TOR inhibitor, which, besides a potent immunosuppressive action including the stimulation of regulatory CD4+foxp3+ T-cells (Tregs), seems to mediate anti-neoplastic effects in MDS and AML. Methods: We report results of a prospective study investigating for the first time a combination of everolimus (days 0–56) with tacrolimus (starting day 0) in 16 patients with MDS (RCMD n=3, RAEB-1 n=3, RAEB-2 n=3, CMMOL-1 n=1, CMMOL-2 n=1, MDS/AML n=1) or de novo AML (n=4) undergoing allogeneic myeloablative conditioning (busulfan 16 mg/kg over 4 days, fludarabine 120 mg/m² over 4 days) followed by a median of 7.0 x 106/kg CD34+ peripheral blood stem cells (PBSC) from related (n=2) or unrelated donors (n=14). It is of note that 5 unrelated donor/recipient pairs displayed one allel-mismatch whereas all others were matched in 10 out 10 HLA characters. The median age of the patients was 61 years (range 47–69) and the majority (n=7) of MDS patients were classified INT-2 or HIGH according to IPSS. Results: All patients engrafted a median of 14 days (platelets) and 17 days (neutrophils) after transplant. On day 21 and 56 after PBSCT the median number of CD4+foxp3+ cells in the blood was not significantly different from normal donors (patients, n=5: 3.2 and 2.3 x 104/ul, controls n=4: 3.7 x 104/ul) Nevertheless, the rate of acute GVHD was moderate with five patients (31 %) developing acute GVHD grade II and only one patient experiencing grade IV GVHD after cessation of immunosuppression due to thrombotic-thrombocytopenic purpura (TTP). Decrease of thrombocytes together clinical signs of TTP were seen in two additional patients while four patients developed VOD of the liver, which was fatal in one case. Extensive chronic GVHD was seen in 50 % of evaluable patients. Mucositis CTC grade III was observed in 5 patients only. The total day 100 mortality rate was 19 % and currently eleven out of sixteen patients (69%) are alive and in remission. Conclusion: Everolimus and tacrolimus are highly efficient in preventing GVHD after unrelated PBSCT in older patients with MDS and AML, which seems not to be mediated by an increase in Tregs. Nevertheless, side effects associated with thrombotic microangiopathy might be more prevalent compared to other regimens.

Abstract We have previously described serious graft-versus-host disease (GVHD) as a highly undesirable outcome after allogeneic hematopoietic cell transplantation (HCT). Serious GVHD encompasses death, lengthy hospitalization, major disability, or recurrent major infections related to either acute or chronic GVHD. In a previous study, we found a 25% incidence of serious GVHD among 171 consecutive patients who had HCT after non-myeloablative (NMA) conditioning between January 1998 and May 2002. To put this observation into perspective, we applied the same criteria for serious GVHD in a cohort of 264 consecutive patients who had HCT after myeloablative (MA) conditioning during the same period of time and compared results with those of the previous study. The overall incidence of serious GVHD was 17% (44/264) in the MA group, compared to 25% (43/171) in the NMA group. There were no statistically significant differences in the incidence of grades III–IV GVHD, extensive chronic GVHD or nonrelapse mortality between the two groups (Table). Patients in the NMA group were older and had higher comorbidity scores than those in the MA group. In the univariate analysis, the hazard ratio (HR) of serious GVHD for the NMA group compared to the MA group was 1.71 (95% C.I., 1.1–2.6) (p = 0.01). After adjusting for patient age, patient and donor gender, donor type, HLA-mismatch, aggressive versus indolent malignancy at HCT, remission versus relapse at HCT, myeloid versus non–myeloid malignancy, HCT co–morbidity index, and prior donor lymphocyte infusion, the HR of serious GVHD was 1.50 (95% C.I., 0.8–2.7) (p = 0.17). After censoring for recurrent or progressive malignancy after HCT, the cumulative incidence of serious GVHD at 3 years was 21% for the NMA group and 14% for the MA group, and the HR was 1.33 (95% C.I., 0.7–2.6) (p = 0.40). Reasons for categorization of GVHD as serious (i.e., death, lengthy hospitalization, major disability, or recurrent major infections) were similar between the MA and NMA cohorts. Among the 44 patients with serious GVHD in the MA group, 19 (43%) had serious acute GVHD, and 25 (57%) had serious chronic GVHD. Among the 43 patients with serious GVHD in the NMA group, 20 (46%) had serious acute GVHD, and 30 (70%) had serious chronic GVHD. Among the 264 MA patients, 28 (11%) had grade III–IV acute GVHD and 147 (56%) had extensive chronic GVHD that did not meet the criteria for serious GVHD, compared to 7 (4%) and 84 (49%) of the 171 NMA patients, respectively. We conclude that the type of pretransplant conditioning regimen does not have a large effect on the incidence of serious GVHD after HCT. Assessment of serious GVHD provides additional useful information to acute GVHD grades and the classification of limited and extensive chronic GVHD in describing overall GVHD-related outcomes after HCT. MA NMA Outcome, n (%) n = 264 n = 171 Serious GVHD 44 (17) 43 (25) Grades III–IV acute GVHD 54 (20) 27 (16) Extensive chronic GVHD 174 (66) 114 (68) 2-year nonrelapse mortality 66 (25) 43 (25)

Abstract Mesenchymal stem cells (MSC) from adult bone marrow have the capacity to differentiate into several mesenchymal tissues and inhibit T-cell alloreactivity in vitro. Within the EBMT MSC expansion consortium we have used MSC to treat grades III–IV acute graft-versus-host disease (GvHD) in 40 patients. The MSC dose was median 1.0 (range 0.4–9) 10^6 cells/kg body weight of the recipient. No side-effects were seen after MSC infusions. Nineteen patients received one dose, 19 patients received two doses, two patients received three and five doses respectively. MSC donors were in five cases HLA-identical sibling donors, 19 haploidentical donors and 41 third-party HLA-mismatched donors. Among the 40 patients treated for severe acute GvHD, 19 had complete responses, nine showed improvement, seven patients did not respond, four had stable disease and one patient was not evaluated due to short follow-up. Twenty-one patients are alive between six weeks up to 3.5 years after transplantation. Nine of these patients have extensive chronic GvHD. One patient with ALL has recurrent leukaemia and one patient has denovo AML of recipient origin. We conclude that MSC have immunomodulatory and tissue repairing effects and should be further explored as treatment of severe acute GvHD in prospective randomized trials.

Abstract Lethal graft-versus-host disease (GVHD) can be induced between MHC-matched murine strains expressing multiple minor histocompatibility antigen (miHA) differences. In the C57BL6 (B6)->BALB.B strain combination, both CD4+ and CD8+ donor T cells can mediate severe lethal GVHD, whereas in the B6->CXB-2 model, in which the CXB-2 strain expresses a subset of the BALB.B miHA, only the CD8+ T cells directly potentiate lethality. We have previously used TCR Vβ CDR3-size spectratype analysis to examine the alloreactive B6 CD4+ and CD8+ T cells, isolated from the lymphohematopoietic compartment after transplantation into both BALB.B and CXB-2 recipients. However, since tissue-specific expression of miHA can potentially elicit differential T cell responses, we have extended our T cell repertoire analysis to examine the responses involved in target tissue damage. Infiltrating host-presensitized B6 CD4+ and CD8+ T cells were isolated post-transplant from the intestines, livers and spleens of lethally irradiated (9 Gy; split-dose) BALB.B and CXB-2 recipients. The results indicated some overlapping Vβ CDR3-size skewing in both the CD4+ and CD8+ T cell repertoires between the BALB.B and CXB-2 recipients within the tissues of each recipient strain. Most notably, spectratype analysis demonstrated tissue specific responses unique to each of the BALB.B and CXB-2 infiltrates. In situ observations of the tissue infiltrating alloreactive T cells were performed by fluorescent microscopy of transplanted B6 T cells constitutively expressing eGFP into BALB.B and CXB-2 recipients, in conjunction with immunohistochemical staining of skewed Vβ families. TUNEL staining was also performed to confirm apoptosis of tissue epithelium. These analyses confirmed the increased infiltration of skewed CD4+ and CD8+ Vβ families within the target tissues.
