Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is a critically important therapy for hematological malignancies, inborn errors of metabolism, and immunodeficiency disorders, yet complications such as graft-vs.-host disease (GvHD) limit survival. Development of anti-GvHD therapies that do not adversely affect susceptibility to infection or graft-vs.-tumor immunity are hampered by the lack of a physiologically relevant, preclinical model of allogeneic HSCT. Here we show a spectrum of diverse clinical HSCT outcomes including primary and secondary graft failure, lethal GvHD, and stable, disease-free full donor engraftment using reduced intensity conditioning and mobilized peripheral blood HSCT in unrelated, fully MHC-matched Mauritian-origin cynomolgus macaques. Anti-GvHD prophylaxis of tacrolimus, post-transplant cyclophosphamide, and CD28 blockade induces multi-lineage, full donor chimerism and recipient-specific tolerance while maintaining pathogen-specific immunity. These results establish a new preclinical allogeneic HSCT model for evaluation of GvHD prophylaxis and next-generation HSCT-mediated therapies for solid organ tolerance, cure of non-malignant hematological disease, and HIV reservoir clearance. Rhesus macaques are not ideal for studying response to allogeneic hematopoietic stem cell transplant (allo-HSCT) owing to complex MHC genetics that prevent full MHC-matching. Here the authors show that inbred Mauritian-origin cynomolgus macaques are a superior preclinical model of allogeneic stem cell transplantation that mimics diverse clinical outcomes of human allo-HSCT.

Abstract
Rationale Effective immunomodulatory therapies for children with life-threatening “cytokine storm” triggered by acute influenza infection are lacking. Understanding the immune profiles of children progressing to severe lung injury and/or septic shock could provide insight into pathogenesis. Objectives To compare the endotracheal and serum cytokine profiles of children with influenza-related critical illness and to identify their associations with severe influenza-associated complications. Methods Children with influenza-related critical illness were enrolled across 32 hospitals in development (N = 171) and validation (N = 73) cohorts (December 2008 through May 2016). Concentrations of 42 cytokines were measured in serum and endotracheal samples and clustered into modules of covarying cytokines. Relative concentrations of cytokines and cytokine modules were tested for associations with acute lung injury (ALI), shock requiring vasopressors, and death/ECMO. Measurements and main results Modules of covarying cytokines were more significantly associated with disease severity than individual cytokines. In the development cohort, increased levels of a serum module containing IL6, IL8, IL10, IP10, GCSF, MCP1, and MIP1α [shock odds ratio (OR) = 3.37, family-wise error rate (FWER) p < 10−4], and decreased levels of a module containing EGF, FGF2, SCD40L, and PAI-1 (shock OR = 0.43, FWER p = 0.002), were both associated with ALI, shock, and death-ECMO independent of age and bacterial coinfection. Both of these associations were confirmed in the validation cohort. Endotracheal and serum cytokine associations differed markedly and were differentially associated with clinical outcomes. Conclusion We identified strong positive and negative associations of cytokine modules with the most severe influenza-related complications in children, providing new insights into the pathogenesis of influenza-related critical illness in children. Effective therapies may need to target mediators of both inflammation and repair.

Abstract
Follistatin is an angiogenic factor elevated in the circulation after
allogeneic hematopoietic cell transplantation (HCT). Elevations in follistatin
plasma concentrations are associated with the onset of and poor survival after
acute graft versus host disease (aGVHD). Using data from the Blood and Marrow
Transplant Clinical Trials Network 0402 study (n=247), we sought to
further quantify the longitudinal associations between plasma follistatin levels
in transplant recipients, as well as baseline HCT donor follistatin levels, and
allogeneic HCT outcomes. Higher recipient baseline follistatin levels were
predictive of development of aGVHD (P=0.04). High donor
follistatin levels were also associated with the incidence of aGVHD
(P<0.01). Elevated follistatin levels on day 28 were
associated with the onset of grade II–IV aGVHD prior to day 28, higher
one-year non-relapse mortality, (NRM), and lower overall survival (OS). In
multivariate analyses, individuals with follistatin levels >1088 pg/mL at day
28 had a four-fold increased risk for NRM (RR=4.3, 95% CI
1.9–9.9, P<0.01) and a nearly three-fold increased
overall risk for mortality (RR=2.8, 95% CI 1.5–5.2,
P<0.01). Given the multiple roles of follistatin in
tissue inflammation and repair, and the confirmation that this biomarker is
predictive of important HCT outcomes, the pathobiology of these relationships
need further study.

Abstract
KEY POINTS Hydrocortisone (HC) is required for activation of large-conductance Ca2+ -activated K+ current (BK) by purinergic receptor agonists. HC reduces insertion of the stress-regulated exon (STREX) in the KCNMA1 gene, permitting protein kinase C (PKC)-dependent channel activation. Overlapping and unique purinergic signalling regions exist at the apical border of differentiated surface cells. BK channels localize in the cilia of surface cells. ABSTRACT In the present study we investigated the role of hydrocortisone (HC) on uridine-5'-triphosphate (UTP)-stimulated ion transport in differentiated, pseudostratified epithelia derived from normal human bronchial basal cells. The presence of a UTP-stimulated, paxilline-sensitive large-conductance Ca2+ -activated K+ (BK) current was demonstrated in control epithelia but was not stimulated in epithelia differentiated in the absence of HC (HC0). Addition of the BK channel opener NS11021 directly activated channels in control epithelia; however, under HC0 conditions, activation only occurred when UTP was added after NS11021. The PKC inhibitors GF109203x and Gö6983 blocked BK activation by UTP in control epithelia, suggesting that PKC-mediated phosphorylation plays a permissive role in purinoceptor-stimulated BK activation. Moreover, HC0 epithelia expressed significantly more KCNMA1 containing the stress-regulated exon (STREX), a splice-variant of the α-subunit that displays altered channel regulation by phosphorylation, compared to control epithelia. Furthermore, BK channels as well as purinergic receptors were shown to localize in unique and overlapping domains at the apical membrane of ciliated surface cells. These results establish a previously unrecognized role for glucocorticoids in regulation of BK channels in airway epithelial cells.

Abstract
Pancreatic cancer is diagnosed at a late stage and has one of the highest cancer mortality rates in the United States, creating an urgent need for novel early detection tools. A candidate biomarker for use in early detection is the soluble MHC class I-related chain A (s-MICA) ligand, which pancreatic tumors shed to escape immune detection. The objective of this study was to define the association between s-MICA levels and pancreatic cancer, in a population-based case-control study. S-MICA was measured in 143 pancreatic cancer cases and 459 controls. Unconditional logistic regression was used to calculate odds ratio (OR) for pancreatic cancer and 95% confidence intervals (CI). There was a positive association between increasing s-MICA levels and pancreatic cancer: compared to the lowest tertile, the ORs for pancreatic cancer were 1.25 (95%CI: 0.75-2.07) and 2.10 (95%CI: 1.29-3.42) in the second and highest tertiles, respectively (P-trend = 0.02). Our study supports previous work demonstrating a positive association between plasma s-MICA levels and pancreatic cancer.

Abstract
10521 Background: Little is known about neurotoxic mechanisms associated with chemotherapy in children with ALL. Cerebrospinal fluid (CSF) biomarkers of brain injury may provide insight into this process. Methods: 235 patients (51% male; mean [SD] age diagnosed 6.8 [4.7] years) treated on a chemotherapy only protocol provided CSF samples following diagnosis and through consolidation. CSF was assayed for biomarkers of myelin degradation (myelin basic protein [MBP]), neuronal damage (nerve growth factor [NGF], total-Tau [T-Tau]) and astrogliosis (glial fibrillary acidic protein [GFAP]). Leukoencephalopathy was evaluated by brain MRI’s during therapy. At ≥5 years post-diagnosis, 138 (70%) of the 198 still eligible survivors (without relapse and unrelated neurologic injury) completed neurocognitive testing and brain diffusion tensor imaging of white matter integrity at age 13.6 [4.6] years. Log-binomial and general linear models were used to examine whether biomarker changes from baseline through consolidation were related to serum methotrexate exposure, acute leukoencephalopathy, and long-term brain outcomes. Results: NGF and T-Tau increased from baseline to consolidation ( P's < 0.001), while MBP and GFAP were elevated at baseline and remained so through consolidation. The number of intrathecal injections (methotrexate, hydrocortisone, cytarabine) was positively correlated with NGF increase at consolidation ( P= 0.005). Increases in GFAP (RR 1.2; 95% CI [1.0 – 1.4]), MBP (RR 1.1 [1.0 – 1.1]) and T-Tau (RR 1.8 [1.1 – 2.8]) were related to higher risk for acute leukoencephalopathy, and higher diffusivity in frontal lobe white matter at ≥5 years post-diagnosis ( P’s < 0.05). Increase in T-Tau at consolidation was associated with worse long-term sustained attention ( P= 0.03), and visual- ( P= 0.04) and visual-motor ( P= 0.02) processing speed. Conclusions: Glial injury, which is evident at diagnosis, may be related to leukemia and methotrexate exposure. Neuronal injury is associated with intrathecal chemotherapy and long-term neurocognitive and brain imaging outcomes. Monitoring CSF biomarkers may be useful in identifying individuals at risk for poor neurological outcomes.

Abstract
Lung transplantation, a cure for a number of end-stage lung diseases, continues to have the worst long-term outcomes when compared with other solid organ transplants. Preclinical modeling of the most common and serious lung transplantation complications are essential to better understand and mitigate the pathophysiological processes that lead to these complications. Various animal and in vitro models of lung transplant complications now exist and each of these models has unique strengths. However, significant issues, such as the required technical expertise as well as the robustness and clinical usefulness of these models, remain to be overcome or clarified. The National Heart, Lung, and Blood Institute (NHLBI) convened a workshop in March 2016 to review the state of preclinical science addressing the three most important complications of lung transplantation: primary graft dysfunction (PGD), acute rejection (AR), and chronic lung allograft dysfunction (CLAD). In addition, the participants of the workshop were tasked to make consensus recommendations on the best use of these complimentary models to close our knowledge gaps in PGD, AR, and CLAD. Their reviews and recommendations are summarized in this report. Furthermore, the participants outlined opportunities to collaborate and directions to accelerate research using these preclinical models.

Abstract
BACKGROUND Long-term survivors of childhood acute lymphoblastic leukemia (ALL) are at risk for neurocognitive impairment, which may be associated with fatigue, sleep problems, systemic inflammation, and oxidative stress. We examined these associations among survivors of childhood ALL treated with chemotherapy only. METHODS Survivors of childhood ALL (male, n = 35 and female, n = 35; mean age, 14.3 years [standard deviation, 4.7 years] and mean years from diagnosis, 7.4 years [standard deviation, 1.9 years]) completed neurocognitive testing, behavioral ratings, and reported sleep quality and fatigue symptoms 5 years after diagnosis. Serum was collected concurrently and assayed for interleukin (IL)-1β and IL-6, tumor necrosis factor α (TNF-α), high-sensitivity C-reactive protein (hsCRP), malondialdehyde, myeloperoxidase, and oxidized low-density lipoprotein. General linear modeling was used to assess associations among biomarkers and functional outcomes, adjusting for age and stratified by sex. RESULTS Survivors performed worse than population norms on executive function and processing speed and reported more behavioral problems (P < .05 adjusted for multiple comparison). In female survivors, fatigue was associated with poor executive function (r = 0.41; P = .02), processing speed (r = 0.56; P < .001), and attention (r = 0.36-0.55; P < .05). Female survivors with frequent nighttime awakening displayed more inattention (P = .01), hyperactivity (P = .03), and aggression (P = .01). Worse executive function, processing speed, and behavioral symptoms were observed in female survivors with higher levels of IL-6, IL-1β, and hsCRP (P < .05). Male survivors with high levels of TNF-α demonstrated worse organization (P = .03), but no significant associations between neurocognitive outcomes and sleep/fatigue measures were observed. CONCLUSION Neurocognitive function in female survivors of childhood ALL appears more susceptible to the effects of sleep disturbance and fatigue. Systemic inflammation may play a role in neurocognitive impairment and behavioral symptoms. Cancer 2017;123:3410-9. © 2017 American Cancer Society.

Abstract
Idiopathic pneumonia syndrome (IPS) is a noninfectious inflammatory disorder of the lungs that occurs most often after fully myeloablative allogeneic hematopoietic stem cell transplantation (HSCT). IPS can be severe and is associated with high 1-year mortality rates despite existing therapies. The canonical nuclear factor-(NF) κB signaling pathway has previously been linked to several inflammatory disorders of the lung, including asthma and lung allograft rejection. It has never been specifically targeted as a novel IPS treatment approach, however. Here, we report that the IκB kinase 2 (IKK2) antagonist BAY 65-5811 or "compound A," a highly potent and specific inhibitor of the NF-κB pathway, was able to improve median survival times and recipient oxygenation in a well-described mouse model of IPS. Compound A impaired the production of the proinflammatory chemokines CCL2 and CCL5 within the host lung after transplantation. This resulted in significantly lower numbers of donor lung infiltrating CD4+ and CD8+ T cells and reduced pulmonary inflammatory cytokine production after allograft. Compound A's beneficial effects appeared to be specific for limiting pulmonary injury, as the drug was unable to improve outcomes in a B6 into B6D2 haplotype-matched murine HSCT model in which recipient mice succumb to lethal acute graft-versus-host disease of the gastrointestinal tract. Collectively, our data suggest that the targeting of the canonical NF-κB pathway with a small molecule IKK2 antagonist may represent an effective and novel therapy for the specific management of acute lung injury that can occur after allogeneic HSCT.

Abstract
Decellularization allows the production of extracellular matrix (ECM) scaffolds. Here we describe the use of combined positive pressure and negative pressure to drive decellularization reagents into the vasculature and airways, respectively, of structurally intact lungs in order to remove cells and cellular material leaving an intact ECM scaffold.

Abstract
Hypertension often occurs in concurrence with obesity and diabetes mellitus, commonly referred to as metabolic syndrome. Renal denervation (RDNx) lowers arterial pressure (AP) and improves glucose metabolism in drug-resistant hypertensive patients with high body mass index. In addition, RDNx has been shown to reduce renal inflammation in the mouse model of angiotensin II hypertension. The present study tested the hypothesis that RDNx reduces AP and renal inflammation and improves glucose metabolism in obesity-induced hypertension. Eight-week-old C57BL/6J mice were fed either a low-fat diet (10 kcal%) or a high-fat diet (45 kcal%) for 10 weeks. Body weight, food intake, fasting blood glucose, and glucose metabolism (glucose tolerance test) were measured. In a parallel study, radiotelemeters were implanted in mice for AP measurement. High fat-fed C57BL/6J mice exhibited an inflammatory and metabolic syndrome phenotype, including increased fat mass, increased AP, and hyperglycemia compared with low-fat diet mice. RDNx, but not Sham surgery, normalized AP in high-fat diet mice (115.8±1.5 mm Hg in sham versus 96.6±6.7 mm Hg in RDNx). RDNx had no significant effect on AP in low-fat diet mice. Also, RDNx had no significant effect on glucose metabolism or renal inflammation as measured by the number of CD8, CD4, and T helper cells or levels of inflammatory cytokines in the kidneys. These results indicate that although renal nerves play a role in obesity-induced hypertension, they do not contribute to impaired glucose metabolism or renal inflammation in this model.

Abstract
Glucocorticoids strongly influence the mucosal-defense functions performed by the bronchial epithelium, and inhaled corticosteroids are critical in the treatment of patients with inflammatory airway diseases such as asthma, chronic obstructive pulmonary disease, and cystic fibrosis. A common pathology associated with these diseases is reduced mucociliary clearance, a defense mechanism involving the coordinated transport of salt, water, and mucus by the bronchial epithelium, ultimately leading to retention of pathogens and particles in the airways and to further disease progression. In the present study we investigated the role of hydrocortisone (HC) in differentiation and development of the ion transport phenotype of normal human bronchial epithelial cells under air-liquid interface conditions. Normal human bronchial epithelial cells differentiated in the absence of HC (HC0) showed significantly less benzamil-sensitive short-circuit current than controls, as well as a reduced response after stimulation with the selective β2-adrenergic receptor agonist salbutamol. Apical membrane localization of epithelial Na(+) channel α-subunits was similarly reduced in HC0 cells compared with controls, supporting a role of HC in the trafficking and density of Na(+) channels in the plasma membrane. Additionally, glucocorticoid exposure during differentiation regulated the transcription of cystic fibrosis transmembrane conductance regulator and β2-adrenergic receptor mRNAs and appeared to be necessary for the expression of cystic fibrosis transmembrane conductance regulator-dependent anion secretion in response to β2-agonists. HC had no significant effect on surface cell differentiation but did modulate the expression of mucin mRNAs. These findings indicate that glucocorticoids support mucosal defense by regulating critical transport pathways essential for effective mucociliary clearance.

Abstract
Programmed death ligand-1 (PD-L1) interaction with PD-1 induces T cell exhaustion and is a therapeutic target to enhance immune responses against cancer and chronic infections. In murine bone marrow transplant models, PD-L1 expression on host target tissues reduces the incidence of graft-versus-host disease (GVHD). PD-L1 is also expressed on T cells; however, it is unclear whether PD-L1 on this population influences immune function. Here, we examined the effects of PD-L1 modulation of T cell function in GVHD. In patients with severe GVHD, PD-L1 expression was increased on donor T cells. Compared with mice that received WT T cells, GVHD was reduced in animals that received T cells from Pdl1-/- donors. PD-L1-deficient T cells had reduced expression of gut homing receptors, diminished production of inflammatory cytokines, and enhanced rates of apoptosis. Moreover, multiple bioenergetic pathways, including aerobic glycolysis, oxidative phosphorylation, and fatty acid metabolism, were also reduced in T cells lacking PD-L1. Finally, the reduction of acute GVHD lethality in mice that received Pdl1-/- donor cells did not affect graft-versus-leukemia responses. These data demonstrate that PD-L1 selectively enhances T cell-mediated immune responses, suggesting a context-dependent function of the PD-1/PD-L1 axis, and suggest selective inhibition of PD-L1 on donor T cells as a potential strategy to prevent or ameliorate GVHD.

Abstract
Pulmonary complications due to infection and idiopathic pneumonia syndrome (IPS), a noninfectious lung injury in hematopoietic stem cell transplant (HSCT) recipients, are frequent causes of transplantation-related mortality and morbidity. Our objective was to characterize the global bronchoalveolar lavage fluid (BALF) protein expression of IPS to identify proteins and pathways that differentiate IPS from infectious lung injury after HSCT. We studied 30 BALF samples from patients who developed lung injury within 180 days of HSCT or cellular therapy transfusion (natural killer cell transfusion). Adult subjects were classified as having IPS or infectious lung injury by the criteria outlined in the 2011 American Thoracic Society statement. BALF was depleted of hemoglobin and 14 high-abundance proteins, treated with trypsin, and labeled with isobaric tagging for relative and absolute quantification (iTRAQ) 8-plex reagent for two-dimensional capillary liquid chromatography (LC) and data dependent peptide tandem mass spectrometry (MS) on an Orbitrap Velos system in higher-energy collision-induced dissociation activation mode. Protein identification employed a target-decoy strategy using ProteinPilot within Galaxy P. The relative protein abundance was determined with reference to a global internal standard consisting of pooled BALF from patients with respiratory failure and no history of HSCT. A variance weighted t-test controlling for a false discovery rate of ≤5% was used to identify proteins that showed differential expression between IPS and infectious lung injury. The biological relevance of these proteins was determined by using gene ontology enrichment analysis and Ingenuity Pathway Analysis. We characterized 12 IPS and 18 infectious lung injury BALF samples. In the 5 iTRAQ LC-MS/MS experiments 845, 735, 532, 615, and 594 proteins were identified for a total of 1125 unique proteins and 368 common proteins across all 5 LC-MS/MS experiments. When comparing IPS to infectious lung injury, 96 proteins were differentially expressed. Gene ontology enrichment analysis showed that these proteins participate in biological processes involved in the development of lung injury after HSCT. These include acute phase response signaling, complement system, coagulation system, liver X receptor (LXR)/retinoid X receptor (RXR), and farsenoid X receptor (FXR)/RXR modulation. We identified 2 canonical pathways modulated by TNF-α, FXR/RXR activation, and IL2 signaling in macrophages. The proteins also mapped to blood coagulation, fibrinolysis, and wound healing-processes that participate in organ repair. Cell movement was identified as significantly over-represented by proteins with differential expression between IPS and infection. In conclusion, the BALF protein expression in IPS differed significantly from infectious lung injury in HSCT recipients. These differences provide insights into mechanisms that are activated in lung injury in HSCT recipients and suggest potential therapeutic targets to augment lung repair.

Abstract
Abstract
T memory stem cells (Tscm) are a subset of antigen-experienced, long-lived, self-renewing and multipotent T cells, which reconstitute immunity following hematopoietic cell transplantation (HCT). Here we investigated the biological role of Tscm in acute Graft-versus-Host Disease (GVHD) using a translational non-human primate model.
Tscm cells were tracked longitudinally following autologous or allogeneic HCT under different immunoprophylaxis regimens, resulting either in fulminant Th1-dependent ‘Primary GVHD’, late-onset Th17-driven ‘Breakthrough GVHD’, or GVHD-free immune tolerance.
Following HCT, Tscm acquired an activated phenotype (Ki67+, CD69+, PD-1+ and CCR5+), but produced low amounts of IFNγ, IL-2, IL-17A, TNFα and Granzyme B. Tscm were a minor population in donor grafts but expanded in peripheral blood (with a reciprocal decline of naïve T cells) early after HCT and then contracted (with a concomitant increase of effector T cells) when recipients developed clinical GVHD. The kinetics of Tscm expansion/contraction correlated closely with clinical disease: Tscm expanded slower and contracted later in animals progressing to Breakthrough compared to Primary GVHD, and Tscm numbers remained stable under tolerizing conditions. At necropsy, animals with GVHD had increased numbers of Tscm in both lymphoid organs (blood, lymph nodes, spleen) and non-lymphoid GVHD-target organs (colon, lungs, liver) compared to GVHD-free animals.
Our data demonstrates that Tscm dynamics correlate with GVHD-free survival and suggest that pathogenic T cells infiltrating both lymphoid and non-lymphoid organs transition from the naïve into the effector state via Tscm. Thus Tscm may play a key role as a cellular reservoir for GVHD.

Abstract
Abstract
Paradoxically, influenza infection can trigger pro- and anti-inflammatory responses, both of which can lead to significant morbidity and mortality. Inflammation can lead to septic shock and acute lung injury (ALI), while suppression can slow viral clearance and increase susceptibility to bacterial coinfection (BCo). We collected and analyzed lung and peripheral blood samples from a multi-center cohort of critically ill children with influenza infection (N = 171) to better understand innate signatures of disease. Samples were collected at admission to the PICU and assayed for levels of 42 cytokines and chemokines. We found intra-compartment analyte correlations were high, while those between compartments were comparatively weak. To increase statistical power and identify groups of co-signaling cytokines, we pre-specified an unsupervised hierarchical clustering analysis to form influenza-specific modules. Some modules were consistent with the literature; e.g. IL4, IL5, IL9 and IL13 (Th2-like) clustered within both compartments. We hypothesized that modules would associate with shock, ALI and death or near death (ECMO). A pro-inflammatory PB module including IL6, IL8, IL10, IP10, GCSF and MCP1 was associated with shock (FWER p<1e-4; OR 3.4) and ALI (FWER p=0.003; OR 2.2), validating previous studies. Inverse associations were also identified with lung and serum modules, only after adjusting for patients’ mean analyte levels, suggesting that relative levels are important. An integrative analysis of lung and PB analytes showed that BCo has a distinct signature from shock that can be used as a biomarker to distinguish the two. Significant modules also generated hypotheses about analytes that could be targeted by novel therapies.

Abstract
Abstract
Cytokines and chemokines are key signaling molecules of the immune system. Recent technological advances enable measurement of multiplexed cytokine profiles in blood as well as sites of infection such as the nasal and alveolar mucosa. These profiles can then be used to identify potential biomarkers of clinical outcomes following influenza infection, by comparing groups of individuals with different outcomes. Recently, several associations between single cytokines and mortality have been reported. However, single analyte association testing ignores context-dependent covariation in cytokine secretion and decreases statistical power due to multiple testing. We have developed a novel data-driven approach to analyze cytokine and chemokine profiles that uses unsupervised clustering to form functional modules. We applied this method to three cohorts of severely ill children infected with influenza. Innate profiles were assayed using a 42-plex Luminex panel at enrollment. Clinical outcomes were collected including hospitalization, septic shock, ALI/ARDS and death. Though many modules were consistent with the immunological literature, some of the modules included cytokines that have not previously been associated, generating novel hypotheses. Modules generated from blood were different than those generated at the site of infection. Furthermore, we found that the modules were significantly associated with clinical outcomes in all three cohorts, while individual cytokines were not statistically significant. Overall, our approach provides a novel method to characterize cytokine and chemokine profiles that both increases statistical power and provides novel hypotheses about context-specific innate signaling.

Abstract
The lung changes functionally and structurally with aging. However, age-related effects on the extracellular matrix (ECM) and corresponding effects on lung cell behavior are not well understood. We hypothesized that ECM from aged animals would induce aging-related phenotypic changes in healthy inoculated cells. Decellularized whole organ scaffolds provide a powerful model for examining how ECM cues affect cell phenotype. The effects of age on ECM composition in both native and decellularized mouse lungs were assessed as was the effect of young vs old acellular ECM on human bronchial epithelial cells (hBECs) and lung fibroblasts (hLFs). Native aged (1 year) lungs demonstrated decreased expression of laminins α3 and α4, elastin and fibronectin, and elevated collagen, compared to young (3 week) lungs. Proteomic analyses of decellularized ECM demonstrated similar findings, and decellularized aged lung ECM contained less diversity in structural proteins compared to young ECM. When seeded in old ECM, hBECs and hLFs demonstrated lower gene expression of laminins α3 and α4, respectively, as compared to young ECM, paralleling the laminin deficiency of aged ECM. ECM changes appear to be important factors in potentiating aging-related phenotypes and may provide clues to mechanisms that allow for aging-related lung diseases.

Abstract
PURPOSE The effectiveness of NK cell infusions to induce leukemic remission is limited by lack of both antigen specificity and in vivo expansion. To address the first issue, we previously generated a bispecific killer engager (BiKE) containing single-chain scFv against CD16 and CD33 to create an immunologic synapse between NK cells and CD33(+) myeloid targets. We have now incorporated a novel modified human IL15 crosslinker, producing a 161533 trispecific killer engager (TriKE) to induce expansion, priming, and survival, which we hypothesize will enhance clinical efficacy. EXPERIMENTAL DESIGN Reagents were tested in proliferation and functional assays and in an in vivo xenograft model of AML. RESULTS When compared with the 1633 BiKE, the 161533 TriKE induced superior NK cell cytotoxicity, degranulation, and cytokine production against CD33(+) HL-60 targets and increased NK survival and proliferation. Specificity was shown by the ability of a 1615EpCAM TriKE to kill CD33-EpCAM(+) targets. Using NK cells from patients after allogeneic stem cell transplantation when NK cell function is defective, the 161533 TriKE restored potent NK function against primary AML targets and induced specific NK cell proliferation. These results were confirmed in an immunodeficient mouse HL-60-Luc tumor model where the 161533 TriKE exhibited superior antitumor activity and induced in vivo persistence and survival of human NK cells for at least 3 weeks. CONCLUSIONS Off-the-shelf 161533 TriKE imparts antigen specificity and promotes in vivo persistence, activation, and survival of NK cells. These qualities are ideal for NK cell therapy of myeloid malignancies or targeting antigens of solid tumors. Clin Cancer Res; 22(14); 3440-50. ©2016 AACRSee related commentary by Talmadge, p. 3419.

Abstract
Interferons (IFNs) have been shown to inhibit influenza A virus (IAV) replication and play an essential role in controlling viral infection. Here we studied the kinetics and magnitude of induction of type I and type III IFN transcripts by primary porcine airway epithelial cells (pAECs) in response to swine and human origin IAV. We observed that swine influenza viruses (SIV) replicate more efficiently than the human pandemic influenza A/California/2009 (pH1N1 CA/09) in pAECs. Interestingly, we also found significant difference in kinetics of IFN-β, IFN-λ1 and IFN-λ3 gene expression by these viruses. While there was delay of up to 12 hours post infection (h p.i.) in induction of IFN genes in pAECs infected with swine IAV A/Sw/Illinois/2008 (H1N1 IL/08), human pH1N1 CA/09 rapidly induced IFN-β, IFN-λ1 and IFN-λ3 gene expression as early as 4 h p.i. However, the magnitude of IFN-β and IFN-λ3 induction at 24 h p.i. was not significantly different between the viral strains tested. Additionally, we found that swine H1N1 IL/08 was less sensitive to dsRNA induced antiviral response compared to human pH1N1 CA/09. Our data suggest that the human and swine IAVs differ in their ability to induce and respond to type I and type III interferons in swine cells. Swine origin IAV may have adapted to the pig host by subverting innate antiviral responses to viral infection.

Abstract
We developed an automated system that can be used to decellularize whole human-sized organs and have shown lung as an example. Lungs from 20 to 30 kg pigs were excised en bloc with the trachea and decellularized with our established protocol of deionized water, detergents, sodium chloride, and porcine pancreatic DNase. A software program was written to control a valve manifold assembly that we built for selection and timing of decellularization fluid perfusion through the airway and the vasculature. This system was interfaced with a prototypic bioreactor chamber that was connected to another program, from a commercial source, which controlled the volume and flow pressure of fluids. Lung matrix that was decellularized by the automated method was compared to a manual method previously used by us and others. Automation resulted in more consistent acellular matrix preparations as demonstrated by measuring levels of DNA, hydroxyproline (collagen), elastin, laminin, and glycosaminoglycans. It also proved highly beneficial in saving time as the decellularization procedure was reduced from days down to just 24 h. Developing a rapid, controllable, automated system for production of reproducible matrices in a closed system is a major step forward in whole-organ tissue engineering.

Abstract
Abstract
Rho-associated kinase 2 (ROCK2) was recently shown to be implicated in regulation of IL-21 and IL-17 secretion in mice and humans. Here, we report that the potent and highly selective ROCK2 inhibitor KD025 effectively reverses an established chronic graft-versus-host (cGVHD) murine model driven by IL-21 and characterized by an aggressive multiorgan system fibrotic disease. KD025 treatment leads to a dose dependent decrease in the development of pathogenic pulmonary function which correlates with a marked reduction of antibody and collagen deposition in the lungs of treated mice to levels comparable to non-cGVHD controls. The spleens of mice treated with KD025 had a decrease in the frequency of germinal centers associated with a reduction in STAT3 and concurrent increase in STAT5 phosphorylation, supporting the molecular mechanism of targeted ROCK2 inhibition in humans. The critical role of STAT3 activation in this cGVHD model was further confirmed by data showing that mice transplanted with inducible STAT3 deficient T cells or BM cells had pulmonary function comparable to the healthy negative controls. Finally, KD025 effectively blocked the progression of sclerodermatous cGVHD model characterized by improvements in weight loss, posture and skin integrity of treated animals. Together, these data demonstrate the importance of ROCK2 signaling in STAT3-dependent regulation of cytokine secretion and highlight the potential of targeted ROCK2 inhibition for cGVHD therapy.

Abstract
Circulating angiogenic factors (AF) reflect tissue healing capacity, although some AF can also contribute to inflammation and are indicative of endothelial dysfunction. The AF milieu in acute graft-versus-host disease (aGVHD) has not been broadly characterized. We hypothesized that patients with abundant AF involved in repair/regeneration versus those mediating damage/inflammation would have improved outcomes. Circulating AF known predominantly for repair/regeneration (epidermal growth factor [EGF], fibroblast growth factor-1 and -2, heparin binding-EGF-like growth factor, and vascular endothelial growth factor-A [VEGF-A], -C, and -D) and for damage/inflammation (angiopoietin-2, endothelin-1, soluble endoglin [sEng], follistatin [FS], leptin, and placental growth factor [PlGF]) were measured in a discovery set of hematopoietic cell recipients with grade III and IV aGVHD and compared with controls, then validated in 2 aGVHD cohorts enrolled in Blood and Marrow Transplant Clinical Trials Network (BMT CTN) trials 0302 (n = 105, serum) and 0802 (n = 158, plasma) versus controls without aGVHD (n = 53, serum). Levels of EGF and VEGF-A were lower than in controls at the onset of aGVHD in both trials and higher with complete response to first-line aGVHD therapy in CTN 0802. FS and PlGF were elevated in aGVHD measured in either serum or plasma. At day 28 after initial aGVHD therapy, elevated FS was an independent negative prognostic factor for survival in both cohorts (hazard ratio, 9.3 in CTN 0302; 2.8 in CTN 0802). These data suggest that circulating AF are associated with clinical outcomes after aGVHD and, thus, may contribute to both pathogenesis and recovery.

Abstract
RATIONALE Much recent interest in lung bioengineering by pulmonary investigators, industry and the organ transplant field has seen a rapid growth of bioreactor development ranging from the microfluidic scale to the human-sized whole lung systems. A comprehension of the findings from these models is needed to provide the basis for further bioreactor development. OBJECTIVE The goal was to comprehensively review the current state of bioreactor development for the lung. METHODS A search using PubMed was done for published, peer-reviewed papers using the keywords "lung" AND "bioreactor" or "bioengineering" or "tissue engineering" or "ex vivo perfusion". MAIN RESULTS Many new bioreactors ranging from the microfluidic scale to the human-sized whole lung systems have been developed by both academic and commercial entities. Microfluidic, lung-mimic and lung slice cultures have the advantages of cost-efficiency and high throughput analyses ideal for pharmaceutical and toxicity studies. Perfused/ventilated rodent whole lung systems can be adapted for mid-throughput studies of lung stem/progenitor cell development, cell behavior, understanding and treating lung injury and for preliminary work that can be translated to human lung bioengineering. Human-sized ex vivo whole lung bioreactors incorporating perfusion and ventilation are amenable to automation and have been used for whole lung decellularization and recellularization. Clinical scale ex vivo lung perfusion systems have been developed for lung preservation and reconditioning and are currently being evaluated in clinical trials. CONCLUSIONS Significant advances in bioreactors for lung engineering have been made at both the microfluidic and the macro scale. The most advanced are closed systems that incorporate pressure-controlled perfusion and ventilation and are amenable to automation. Ex vivo lung perfusion systems have advanced to clinical trials for lung preservation and reconditioning. The biggest challenges that lie ahead for lung bioengineering can only be overcome by future advances in technology that solve the problems of cell production and tissue incorporation.

Abstract
Abstract
Chronic graft versus host disease (cGVHD) is a life threatening impediment to the otherwise curative potential of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Intensive study has unveiled the lymphoid subsets that drive multifaceted autoimmune and fibrotic cascades which disrupt healthy tissues. Clinical and in-vivo data implicate B-cells and certain subsets of CD4 helper T-cells in the development and progression of cGVHD. These specific immune subsets are unique in their singular dependence upon the TEC-family kinases BTK or ITK for receptor driven activation. Ibrutinib is an irreversible inhibitor of BTK and ITK that has produced durable remissions in B-cell malignancies with minimal toxicity. We sought to examine ibrutinib's potential to attenuate B-cell and CD4 T-cell driven anti-host immunity in the setting of cGVHD. We utilized two complementary murine models independently focused on interrogating sclerodermatous T-cell driven cGVHD (LPJ→C57BL/6) or alloantibody driven bronchiolar obliterans (BO) and multi-organ system disease without skin involvement (C57BL/6→B10.BR). We examined therapeutic administration of 25mg/kg/day ibrutinib initiated when mice first develop signs of cGVHD (25-28 days after allo-HSCT). In the minor-MHC mismatch LPJ→C57BL/6 model, ibrutinib significantly extended median time to cGVHD progression by 14 days and 33% (6 of 18) of ibrutinib treated mice remained progression free as compared to 12% (2 of 18) of mice receiving vehicle and 10% (1 of 11) of mice receiving cyclosporine 10mg/kg/day (p<0.02). Overall survival was also highest in the ibrutinib treatment cohort. Mice receiving ibrutinib showed restoration of external cGVHD criterion including body weight, posture, skin lesions, hair loss, and mobility. There was significant ablation of lymphohistiocytic T- and B-cell pulmonary and renal infiltration in ibrutinib treated animals. Data from the C57BL/6→B10.BR model confirmed the efficacy of ibrutinib in significantly restoring pulmonary compliance, elastance, and resistance to levels indistinguishable from that of a healthy animal and significantly better than cGVHD vehicle treated controls (n=12/group)(p<0.01). These results were associated with significantly decreased alloantibody deposition and decreased fibrosis in the lungs of ibrutinib treated mice. Germinal center (GC) reactions, required for multi-organ system pathology in this model, were also significantly reduced within the spleens of mice receiving therapeutic ibrutinib (p<0.05). Using in-vivo genetic ablation models, we demonstrate the critical nature of BTK and ITK respectively in the development of cGVHD pathognomonic BO. Our data support ibrutinib as a promising therapeutic direction for the treatment of cGVHD by virtue of its ability to suppress BTK and ITK signaling.

Abstract
Chronic graft-versus-host disease (cGVHD) is a life-threatening impediment to allogeneic hematopoietic stem cell transplantation, and current therapies do not completely prevent and/or treat cGVHD. CD4+ T cells and B cells mediate cGVHD; therefore, targeting these populations may inhibit cGVHD pathogenesis. Ibrutinib is an FDA-approved irreversible inhibitor of Bruton's tyrosine kinase (BTK) and IL-2 inducible T cell kinase (ITK) that targets Th2 cells and B cells and produces durable remissions in B cell malignancies with minimal toxicity. Here, we evaluated whether ibrutinib could reverse established cGVHD in 2 complementary murine models, a model interrogating T cell-driven sclerodermatous cGVHD and an alloantibody-driven multiorgan system cGVHD model that induces bronchiolar obliterans (BO). In the T cell-mediated sclerodermatous cGVHD model, ibrutinib treatment delayed progression, improved survival, and ameliorated clinical and pathological manifestations. In the alloantibody-driven cGVHD model, ibrutinib treatment restored pulmonary function and reduced germinal center reactions and tissue immunoglobulin deposition. Animals lacking BTK and ITK did not develop cGVHD, indicating that these molecules are critical to cGVHD development. Furthermore, ibrutinib treatment reduced activation of T and B cells from patients with active cGVHD. Our data demonstrate that B cells and T cells drive cGVHD and suggest that ibrutinib has potential as a therapeutic agent, warranting consideration for cGVHD clinical trials.

Abstract
RATIONALE Obliterative bronchiolitis (OB) is a significant cause of morbidity and mortality after lung transplant and hematopoietic cell transplant. Mesenchymal stromal cells (MSCs) have been shown to possess immunomodulatory properties in chronic inflammatory disease. OBJECTIVE Administration of MSCs was evaluated for the ability to ameliorate OB in mice using our established allogeneic bone marrow transplant (BMT) model. METHODS Mice were lethally conditioned and received allogeneic bone marrow without (BM) or with spleen cells (BMS), as a source of OB-causing T-cells. Cell therapy was started at 2 weeks post-transplant, or delayed to 4 weeks when mice developed airway injury, defined as increased airway resistance measured by pulmonary function test (PFT). BM-derived MSC or control cells [mouse pulmonary vein endothelial cells (PVECs) or lung fibroblasts (LFs)] were administered. Route of administration [intratracheally (IT) and IV] and frequency (every 1, 2 or 3 weeks) were compared. Mice were evaluated at 3 months post-BMT. MEASUREMENTS AND MAIN RESULTS No ectopic tissue formation was identified in any mice. When compared to BMS mice receiving control cells or no cells, those receiving MSCs showed improved resistance, compliance and inspiratory capacity. Interim PFT analysis showed no difference in route of administration. Improvements in PFTs were found regardless of dose frequency; but once per week worked best even when administration began late. Mice given MSC also had decreased peribronchiolar inflammation, lower levels of hydroxyproline (collagen) and higher frequencies of macrophages staining for the alternatively activated macrophage (AAM) marker CD206. CONCLUSIONS These results warrant study of MSCs as a potential management option for OB in lung transplant and BMT recipients.

Abstract
OBJECTIVE Assessing and treating pain in nonverbal children with developmental disabilities are a clinical challenge. Current assessment approaches rely on clinical impression and behavioral rating scales completed by proxy report. Given the growing health relevance of the salivary metabolome, we undertook a translational-oriented feasibility study using proton nuclear magnetic resonance (NMR) spectroscopy and neuropeptide/cytokine/hormone detection to compare a set of salivary biomarkers relevant to nociception. DESIGN Within-group observational design. SETTING Tertiary pediatric rehabilitation hospital. SUBJECTS Ten nonverbal pediatric patients with cerebral palsy with and without pain. METHODS Unstimulated (passively collected) saliva was collected using oral swabs followed by perchloric acid extraction and analyzed on a Bruker Avance 700 MHz NMR spectrometer. We also measured salivary levels of several cytokines, chemokines, hormones, and neuropeptides. RESULTS Partial least squares discriminant analysis showed separation of those children with/without pain for a number of different biomarkers. The majority of the salivary metabolite, neuropeptide, cytokine, and hormone levels were higher in children with pain vs no pain. CONCLUSIONS The ease of collection and noninvasive manner in which the samples were collected and analyzed support the possibility of the regular predictive use of this novel biomarker-monitoring method in clinical practice.

Abstract
Acute graft-versus-host disease (aGvHD) is a major limitation to the use of allogeneic stem cell transplantation for the treatment of patients with relapsed malignant disease. Previous work using animals lacking secondary lymphoid tissue (SLT) suggested that activation of donor T cells in SLT is critically important for the pathogenesis of aGvHD. However, these studies did not determine if impaired migration into, and more importantly, out of SLT, would ameliorate aGvHD. Here, we show that T cells from mice lacking Coronin 1A (Coro 1A(-/-)), an actin-associated protein shown to be important for thymocyte egress, do not mediate acute GvHD. The attenuation of aGvHD was associated with decreased expression of the critical trafficking proteins C-C chemokines receptor type 7 (CCR7) and sphingosine 1 phosphate receptor on donor T cells. This was mediated in part by impaired activation of the canonical NF-κB pathway in the absence of Coro 1A. As a result of these alterations, donor T cells from Coro 1A(-/-) mice were not able to initially traffic to SLT or exit SLT after BM transplantation. However, this alteration did not abrogate the graft-versus-leukemia response. Our data suggest that blocking T-cell migration into and out of SLT is a valid approach to prevent aGvHD.

Abstract
Chronic GVHD (cGVHD) is dependent on the ability of donor bone marrow (BM) B cells to produce pathogenic antibody (Ab) deposited in target organs, which is associated with increased germinal centers (GCs). BTK is necessary for B cells to enter GCs and ITK is necessary for T cell activation. We hypothesized that alloreactive GC B cells and T follicular helper cells require BTK or ITK and inhibition by ibrutinib (Ib) would prevent cGVHD. We evaluated the therapeutic effect of Ib in two models of cGVHD: a MHC-disparate (B6→B10.BR) multi-organ model complicated by bronchiolitis obliterans (BO) and a sclerodermatous (SCL) minor-mismatch (LP/J→B6) model. Mice treated with Ib had a decrease in pathogenic Ab, collagen deposition and GC B cells in target organs similar to healthy control mice. In contrast to cGVHD mice, pulmonary function in Ib treated mice was similar to control mice. To confirm that BTK and ITK are required for cGVHD we used donor mice with an ablation of BTK or ITK. Absence of BTK in B cells impeded GCs, Ab deposition and BO. Mice transplanted with T cells lacking ITK and WT BM did not develop BO. In the SCL model, mice treated with Ib did not develop clinical signs of cGVHD including less alopecia and SCL lesions. Furthermore, there was a decrease in lymphocyte infiltration surrounding the bronchioles and nephrons in treated mice. The inhibition of TEC-family kinases with Ib is a novel therapeutic for multi-organ system cGVHD with BO or SCL manifestations.

Abstract
Club cell secretory protein (CCSP) is an indirect phospholipase A2 inhibitor with some immunosuppressive and antiproliferative properties that is expressed in bronchiolar Club cells. In our murine bone marrow transplant (BMT) model of obliterative bronchiolitis (OB), CCSP is diminished; however, its role is unknown. To determine the role of CCSP, B6 wild-type (WT) or CCSP-deficient (CCSP(-/-)) mice were lethally conditioned and given allogeneic bone marrow with a sublethal dose of allogeneic splenic T cells to induce OB. We found that CCSP(-/-) mice demonstrated a higher mortality following BMT-induced OB compared with WT mice. Mice were analyzed 60 days post-BMT for protein expression, pulmonary function, and histology. CCSP levels were reduced in WT mice with BMT-induced OB, and lower levels correlated to decreased lung compliance. CCSP(-/-) had a higher degree of injury and fibrosis as measured by hydroxy proline, along with an increased lung resistance and the inflammatory markers, leukotriene B4 and CXCL1. Replacement with recombinant intravenous CCSP partially reversed the weight loss and improved survival in the CCSP(-/-) mice. In addition, CCSP replacement improved histology and decreased inflammatory cells and markers. These findings indicate that CCSP has a regulatory role in OB and may have potential as a preventive therapy.

Abstract
This study evaluates the mechanism by which bispecific and trispecific killer cell engagers (BiKEs and TriKEs) act to trigger human natural killer (NK) cell effector function and investigates their ability to induce NK cell cytokine and chemokine production against human B-cell leukemia. We examined the ability of BiKEs and TriKEs to trigger NK cell activation through direct CD16 signaling, measuring intracellular Ca²⁺ mobilization, secretion of lytic granules, induction of target cell apoptosis, and production of cytokine and chemokines in response to the Raji cell line and primary leukemia targets. Resting NK cells triggered by the recombinant reagents led to intracellular Ca²⁺ mobilization through direct CD16 signaling. Coculture of reagent-treated resting NK cells with Raji targets resulted in significant increases in NK cell degranulation and target cell death. BiKEs and TriKEs effectively mediated NK cytotoxicity of Raji targets at high and low effector-to-target ratios and maintained functional stability after 24 and 48 hours of culture in human serum. NK cell production of IFN-γ, TNF-α, granulocyte macrophage colony-stimulating factor (GM-CSF), interleukin (IL)-8, macrophage inflammatory protein (MIP)-1α, and regulated and normal T cell expressed and secreted (RANTES) was differentially induced in the presence of recombinant reagents and Raji targets. Moreover, significant increases in NK cell degranulation and enhancement of IFN-γ production against primary acute lymphoblastic leukemia and chronic lymphocytic leukemia targets were induced with reagent treatment of resting NK cells. In conclusion, BiKEs and TriKEs directly trigger NK cell activation through CD16, significantly increasing NK cell cytolytic activity and cytokine production against tumor targets, showing their therapeutic potential for enhancing NK cell immunotherapies for leukemias and lymphomas.

Abstract
The toll-like receptor (TLR) 7 agonist 852A, a small-molecule imidazoquinoline, stimulates plasmacytoid dendritic cells to produce multiple cytokines. We conducted a Phase II study of 852A in patients with recurrent hematologic malignancies. The primary objective was assessing the activity of 852A administered subcutaneously twice weekly for 12 weeks. Secondary objectives were assessing the safety of 852A and its ability to activate the immune system with prolonged dosing. Patients with relapsed hematologic malignancies of any age with adequate organ function were eligible. Patients initiated dosing at 0.6 mg/m(2) twice weekly and escalated by 0.2 mg/m(2) after every two doses as tolerated to a target dose of 1.2 mg/m(2) . Patients with responses or stable disease were eligible for additional cycles. Seventeen patients (15 males) entered the study: 6 with AML, 5 ALL, 4 NHL, 1 Hodgkin's lymphoma, and 1 multiple myeloma. The mean age was 41 years (12-71 years). The median number of prior chemotherapy regimens was 5 (range = 1-14). Thirteen patients completed all 24 injections. Grade 3-4 toxicities included nausea, dyspnea, fever, myalgia, malaise, and cough. Responses included one complete response (ALL), one partial response (AML), two stable disease (AML and NHL), and 9 progressive disease. This is the first in-human hematologic malignancy trial of a subcutaneously (SC) delivered TLR7 agonist using a prolonged dosing schedule. 852A was safely administered up to 1.2 mg/m(2) twice weekly with evidence of sustained tolerability and clinical activity in hematologic malignancies. Systemic TLR agonists for the treatment of hematologic malignancies warrant further study.

Abstract
Graft-versus-host disease (GVHD) remains the most significant complication after allogeneic stem cell transplantation. Previously, acute GVHD had been considered to be mediated predominantly by Th1-polarized T cells. Recently, investigators have identified a second proinflammatory lineage of T cells termed Th17 that is critically dependent on the transcription factor retinoic acid-related orphan receptor (ROR)γt. In this study, we have evaluated the role of Th17 cells in murine acute GVHD by infusing donor T cells lacking RORC and as a consequence the isoform RORγt. Recipients given donor CD4(+) and CD8(+) T cells lacking RORC had significantly attenuated acute GVHD and markedly decreased tissue pathology in the colon, liver, and lung. Using a clinically relevant haploidentical murine transplantation model, we showed that RORC(-/-) CD4(+) T cells alone diminished the severity and lethality of acute GVHD. This was not found when CD4(+) T cells from RORC(-/-) mice were given to completely mismatched BALB/c mice, and it was correlated with absolute differences in the generation of TNF in the colon after transplant. Thus, CD4(+) T cell expression of RORC is important in the pathogenesis of acute GVHD.

Abstract
UNLABELLED ABSTRACT Background: Obliterative bronchiolitis (OB) is a major obstacle to the success of lung transplantation and is also a serious complication of hematopoietic stem cell transplant. It has few therapeutic options and respiratory delivery of potential therapeutic drugs is hindered by the narrowed and occluded airways. METHODS OB was induced in mice using an established protocol and lung function was assessed by plethysmograph. Mice were exposed to four different aerosols of aluminum phthalocyanine tetrasulfonic acid (AlPCS) that ranged in concentration and median particle size distribution (0.2-4.0 μm). The fluorescent intensity and number of pixels were measured for the trachea and lobes at two different compressional thicknesses. With analysis of the fluorescent intensity, the concentration and attenuation coefficient were estimated for each lobe and the trachea as well as individual pixels. The latter allowed generation of images reflective of the concentration. RESULTS Lungs/trachea from OB mice had lower deposition, which correlated with lung function measurements, and apparent greater variability in the intensity compared to controls. The estimated lung volumes measured by plethysmograph were not different between the OB group and controls; however, total inflational lung capacity was reduced in OB mice. CONCLUSIONS Despite the variability in disease induction, there is a clear link between aerosol deposition and lung function, which was revealed by fluorescent imaging. The modulation of aerosol deposition in lungs with restrictive airway disease underscores the importance of tailoring aerosolization to optimize drug delivery.

Abstract
Bacterial lipoproteins (BLP) induce innate immune responses in mammals by activating heterodimeric receptor complexes containing Toll-like receptor 2 (TLR2). TLR2 signaling results in nuclear factor-kappaB (NF-κB)-dependent upregulation of anti-apoptotic factors, anti-oxidants and cytokines, all of which have been implicated in radiation protection. Here we demonstrate that synthetic lipopeptides (sLP) that mimic the structure of naturally occurring mycoplasmal BLP significantly increase mouse survival following lethal total body irradiation (TBI) when administered between 48 hours before and 24 hours after irradiation. The TBI dose ranges against which sLP are effective indicate that sLP primarily impact the hematopoietic (HP) component of acute radiation syndrome. Indeed, sLP treatment accelerated recovery of bone marrow (BM) and spleen cellularity and ameliorated thrombocytopenia of irradiated mice. sLP did not improve survival of irradiated TLR2-knockout mice, confirming that sLP-mediated radioprotection requires TLR2. However, sLP was radioprotective in chimeric mice containing TLR2-null BM on a wild type background, indicating that radioprotection of the HP system by sLP is, at least in part, indirect and initiated in non-BM cells. sLP injection resulted in strong transient induction of multiple cytokines with known roles in hematopoiesis, including granulocyte colony-stimulating factor (G-CSF), keratinocyte chemoattractant (KC) and interleukin-6 (IL-6). sLP-induced cytokines, particularly G-CSF, are likely mediators of the radioprotective/mitigative activity of sLP. This study illustrates the strong potential of LP-based TLR2 agonists for anti-radiation prophylaxis and therapy in defense and medical scenarios.

Abstract
Better methods are needed to quantify the distribution of drug among the airways of the lungs of small animals to facilitate the development of agents that can target specific airways. Mice were exposed to aerosols of aluminum phthalocyanine tetrasulfonic acid (AlPCS) that ranged in concentration and size (0.2-2.8 μm). The trachea and lobes were removed and placed between glass slides, and fluorescent images were obtained at two different compression thicknesses. The intensity, normalized by the area, exposure time, and thickness, was then plotted as a function of compression thickness, from which the concentration and attenuation coefficient were estimated for each lobe and then for each pixel of the image. The latter was then used to generate an image reflective of the concentration. The lobe volume, concentration, and tissue attenuation of AlPCS was consistent among the lobes. The deposition fraction increased with decreasing particle size. The network of lines in the concentration image indicated that connective tissue has a lower concentration. The central airways were clearly evident in the images of mice exposed to the very small and large aerosols. This approach provides a rapid, economical means to obtain high resolution images of mouse lungs from which detailed analysis of the distribution of deposited aerosol particles can be obtained.

Abstract
Idiopathic pneumonia syndrome (IPS) is a significant cause of morbidity and mortality post-bone marrow transplantation (BMT) in humans. In our established murine IPS model in which lethally conditioned recipients are given allogeneic bone marrow and splenocytes, recruitment of host monocytes occurs early post-BMT, followed by donor T cells concomitant with development of severe lung dysfunction. Because matrix metalloproteinase 12 (MMP12) is important for macrophage infiltration and injury in other mouse models of lung disease such as emphysema, lethally conditioned MMP12(-/-) mice were used as allogeneic recipients to determine whether MMP12 plays a similar role in potentiating lung injury in IPS. Surprisingly, MMP12(-/-) mice developed IPS and exhibited an accelerated allogeneic T cell-dependent decrease in compliance compared with wild-type (WT) recipients. MMP12(-/-), but not WT, mice also had allogeneic T cell-dependent elevated lung resistance post-BMT. Recruitment of monocytes and T cells into the lungs was not altered on day 7 post-BMT, but the lungs of MMP12(-/-) recipients had increased collagen deposition, a feature normally not seen in our IPS model. MMP12(-/-) mice had a compensatory increase in MMP2 in the lungs post-BMT, as well as increased β6-integrin compared with WT recipients, and only in the presence of allogeneic T cells. Levels of total transforming growth factor (TGF)-β1 protein in the lungs were elevated compared with WT recipients, consistent with the profibrotic function of β6-integrin as an activator of TGF-β. These data indicate that host-derived MMP12 may be important in limiting development of IPS by allowing proper remodeling of extracellular matrix and effective repair of BMT-related injury.

Abstract
RATIONALE Acute lung dysfunction of noninfectious etiology, known as idiopathic pneumonia syndrome (IPS), is a severe complication following hematopoietic stem cell transplantation (HSCT). Several mouse models have been recently developed to determine the underlying causes of IPS. A cohesive interpretation of experimental data and their relationship to the findings of clinical research studies in humans is needed to better understand the basis for current and future clinical trials for the prevention/treatment of IPS. OBJECTIVES Our goal was to perform a comprehensive review of the preclinical (i.e., murine models) and clinical research on IPS. METHODS An ATS committee performed PubMed and OVID searches for published, peer-reviewed articles using the keywords "idiopathic pneumonia syndrome" or "lung injury" or "pulmonary complications" AND "bone marrow transplant" or "hematopoietic stem cell transplant." No specific inclusion or exclusion criteria were determined a priori for this review. MEASUREMENTS AND MAIN RESULTS Experimental models that reproduce the various patterns of lung injury observed after HSCT have identified that both soluble and cellular inflammatory mediators contribute to the inflammation engendered during the development of IPS. To date, 10 preclinical murine models of the IPS spectrum have been established using various donor and host strain combinations used to study graft-versus-host disease (GVHD). This, as well as the demonstrated T cell dependency of IPS development in these models, supports the concept that the lung is a target of immune-mediated attack after HSCT. The most developed therapeutic strategy for IPS involves blocking TNF signaling with etanercept, which is currently being evaluated in clinical trials. CONCLUSIONS IPS remains a frequently fatal complication that limits the broader use of allogeneic HSCT as a successful treatment modality. Faced with the clinical syndrome of IPS, one can categorize the disease entity with the appropriate tools, although cases of unclassifiable IPS will remain. Significant research efforts have resulted in a paradigm shift away from identifying noninfectious lung injury after HSCT solely as an idiopathic clinical syndrome and toward understanding IPS as a process involving aspects of both the adaptive and the innate immune response. Importantly, new laboratory insights are currently being translated to the clinic and will likely prove important to the development of future strategies to prevent or treat this serious disorder.
