Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) shows promising therapeutic potential in cancer treatment as it is able to trigger extrinsic apoptotic pathways by binding to the cognate death receptor, causing broad-spectrum apoptosis in cancer cells with negligible toxicity to normal cells. However, the majority of cancers display resistance to TRAIL, limiting its clinical utility. Overcoming resistance to TRAIL therapies remains a challenge in the development of effective anti-cancer strategies. To address the limitations of TRAIL therapy, a viable alternative approach involves combining TRAIL with more potent drugs compared to monotherapy. This combination strategy aims to induce synergistic effects or sensitize drug-resistant cancer cells. This review provides an overview of relevant modalities of TRAIL combination therapy, highlighting different drug classes. The findings demonstrate that combining TRAIL with other agents can effectively counteract resistance observed with TRAIL therapies in cancer. These findings lay a foundation for future advancements in TRAIL-based therapies for treating various cancers.

Exp Dermatol 2024; 33:e14881.

Abstract
Abnormal death of neutrophils and the subsequent ineffective clearance of cell fragments result in production of autoantigens that can lead to systemic lupus erythematosus (SLE). Excessive formation of neutrophil extracellular traps (NETs) can trigger the synthesis of pro-inflammatory cytokines such as type I interferons, leading to tissue damage and immune dysfunction in SLE patients. In this study, we found that a decrease in neutrophil counts in the peripheral blood was correlated with clinical parameters in SLE patients. Patients with low neutrophil counts had high renal activity index and chronicity index scores. NET formation and neutrophil autophagy in SLE patients were increased. The autophagy inhibitor hydroxychloroquine was shown to restrict NET formation. Using comprehensive bioinformatics analysis, we found that the expression of the autophagy-related gene, hypoxia-inducible factor 1A (HIF1A), was enhanced in peripheral neutrophils and in the renal glomeruli in SLE patients. Targeting HIF1A could be a potential therapeutic approach for SLE.

Abstract
Autoimmune heart disease is a non-random condition characterised by immune system-mediated aggression against cardiac tissue. Cardiac changes often exhibit nonspecific features and, if unrecognised, can result in fatal outcomes even among seemingly healthy young individuals. In the absence of reliable medical history, the primary challenge lies in differentiating between the various cardiopathies. Numerous immunohistochemical and genetic studies have endeavoured to characterise distinct types of cardiopathies, facilitating their differentiation during autopsy examinations. However, the presence of a standardised protocol that forensic pathologists can employ to guide their investigations would be beneficial. Hence, this summary aims to present the spectrum of autoimmune cardiopathies, including emerging insights such as SARS-CoV-2-induced cardiopathies, and proposes the utilisation of practical tools, such as blood markers, to aid forensic pathologists in their routine practice.

Abstract
Tumour necrosis factor–related apoptosis‐inducing ligand (TRAIL) is a member of the tumour necrosis factor (TNF) superfamily which mainly induces apoptosis of tumour cells and transformed cell lines with no systemic toxicity, whereas they share high sequence homology with TNF and CD95L. These unique effects of TRAIL have made it an important molecule in oncology research. However, the research on TRAIL‐related antineoplastic agents has lagged behind and has been limited by the extensive drug resistance in cancer cells. Given the several findings showing that TRAIL is involved in immune regulation and other pleiotropic biological effects in non‐malignant cells, TRAIL and its receptors have attracted widespread attention from researchers. In the central nervous system (CNS), TRAIL is highly correlated with malignant tumours such as glioma and other non‐neoplastic disorders such as acute brain injury, CNS infection and neurodegenerative disease. Many clinical and animal studies have revealed the dual roles of TRAIL in which it causes damage by inducing cell apoptosis, and confers protection by enhancing both pro‐ and non‐apoptosis effects in different neurological disorders and at different sites or stages. Its pro‐apoptotic effect produces a pro‐survival effect that cannot be underestimated. This review extensively covers in vitro and in vivo experiments and clinical studies investigating TRAIL. It also provides a summary of the current knowledge on the TRAIL signalling pathway and its involvement in pathogenesis, diagnosis and therapeutics of CNS disorders as a basis for future research.

Abstract
Granulocyte-macrophage colony-stimulating factor (GM-CSF) was first described as a growth factor that induces the differentiation and proliferation of myeloid progenitors in the bone marrow. GM-CSF also has an important cytokine effect in chronic inflammatory diseases by stimulating the activation and migration of myeloid cells to inflammation sites, promoting survival of target cells and stimulating the renewal of effector granulocytes and macrophages. Because of these pro-cellular effects, an imbalance in GM-CSF production/signaling may lead to harmful inflammatory conditions. In this context, GM-CSF has a pathogenic role in autoimmune diseases that are dependent on cellular immune responses such as multiple sclerosis (MS) and rheumatoid arthritis (RA). Conversely, a protective role has also been described in other autoimmune diseases where humoral responses are detrimental such as myasthenia gravis (MG), Hashimoto's thyroiditis (HT), inflammatory bowel disease (IBD), and systemic lupus erythematosus (SLE). In this review, we aimed for a comprehensive analysis of literature data on the multiple roles of GM-CSF in autoimmue diseases and possible therapeutic strategies that target GM-CSF production.

Abstract
AIM The purpose of this study was to evaluate the relationship between monocyte to high-density lipoprotein cholesterol ratio (MHR) and carotid atherosclerostic plaque in patients with systemic lupus erythematosus (SLE). METHODS A total of 214 SLE patients were divided into two groups according to the results of ultrasonic examination: carotid arterial atherosclerotic plaque groups and noncarotid arterial atherosclerosis groups. RESULTS The values of monocyte to high-density lipoprotein-cholesterol ratio (MHR) increase in carotid arterial atherosclerotic plaque groups compared with noncarotid arterial atherosclerosis groups (0.32 ± 0.18 vs 0.26 ± 0.15; p = 0.015). There was a significant correlation between MHR and carotid artery intima-media thickness (r = 0.228; p = 0.001) in patients with SLE. CONCLUSION Our study suggests that the values of MHR could be a marker to assess carotid artery intima-media thickness in patients with SLE.

Abstract
Background. Systemic lupus erythematosus (SLE) is a chronic, inflammatory, connective tissue disease that commonly affects the joints and a variety of organs due to an overactivation of the body's immune system. There is wide heterogeneity in presentation of SLE patients, including lung, central nervous system, skin, kidney, and hematologic manifestations. Case Presentation. We report a case of atypical manifestation of SLE in a 53-year-old man who presented with neutropenic fever. Physical findings of interest included oral ulcers on the lower lip, a malar-like rash across the bridge of the nose, and a discoid-like rash on extensor surfaces of the elbows and knees. Labs include ANC <100, weakly positive anti-dsDNA, negative ANA, ferritin 1237 ng/mL, low C3/C4, and positive direct Coombs' test. A thorough workup for infection and hematologic malignancy was negative. Two days after initiation of therapy with 25 mg IV solumedrol twice a day, the patient's daily fevers resolved. ANC drastically improved to 2000 after two weeks of steroid treatment. He was later found to have a high titer of anti-neutrophil antibodies. Discussion. Autoimmune leukopenia is a common presentation in SLE, occurring in 50-60% of patients. Severe autoimmune neutropenia is uncommon and may correlate with high anti-neutrophil antibody activity despite a negative ANA. As neutropenia is usually mild, there are currently no guidelines for therapy. For our patient, we started him on low dose IV solumedrol and found that he responded drastically to treatment. Given strongly positive nonspecific anti-neutrophil antibodies in the setting of a negative ANA noted in our patient, it is likely that there are other currently unknown antibodies associated with SLE which may correlate strongly with autoimmune neutropenia.

Abstract
The objective of this study was to determine potential relationship between the levels of serum TNF-related apoptosis inducing ligand (TRAIL) and osteoprotegerin (OPG) and clinical markers in systemic lupus erythematosus (SLE) patients. Forty SLE patients with inactive disease were enrolled in this study. For comparison, 20 Sjögren's syndrome (SS) patients and 30 normal controls were also analysed. Serum levels of TRAIL and OPG were determined by ELISA. Serum TRAIL and OPG concentrations in SLE patients were significantly ( P < 0.05) higher than those in healthy volunteers. Of note, serum TRAIL but not OPG was significantly ( P < 0.05) higher in the SLE patient subset characterized by the presence of anti-SSA/SSB antibodies. The relationship between high levels of TRAIL and SSA/SSB antibodies was further supported by the analysis of SS patients characterized by SSA/SSB antibodies positivity, in which TRAIL levels resulted comparable to the subgroup of anti-SSA/SSB positive SLE patients. The presence of SSA/SSB antibodies, targeting a specific subset of SLE and SS patients, is related to increased serum levels of TRAIL but not of OPG. Lupus (2007) 16, 479—482.

Abstract
Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely. Glucocorticoids are used as first-line therapy in patients with SLE with AIHA, but there is no conclusive evidence to guide second-line therapy. Rituximab is promising in refractory and non-responding AIHA. TTP is not recognised as a criteria for classification of SLE, but there is a considerable overlap between the presenting features of TTP and SLE, and a few patients with SLE have concurrent TTP. Myelofibrosis is an uncommon yet well-documented manifestation of SLE. We have compiled the cases that were reported in MEDLINE sources.

Abstract
UNLABELLED This article is a review of different management strategies for the hematological manifestations of systemic lupus erythematosus (SLE), the strategies include immunosuppressive drugs, some noval therapies and B-cell depletion for refractory thrombocytopenia in patients with SLE and in antiphospholipid antibody syndrome associated with SLE. The researcher questions the validity of the current classic treatment modes and the article explores the relationships between SLE hematological manifestations and the level of morbidity and mortality burden and focuses on the pathophysiology, diagnostic approaches and management strategies of these manifestations. The researcher focuses on hematological abnormalities because they are the commonest among most manifestations in SLE seen in Anemia, leucopenias and thrombocytopenia. They commonly result from an immune mediated bone marrow failure, excessive peripheral cells destruction or certain drugs and infections. There is also an association between anti-phospholipid antibody syndrome (APS) and SLE referred to as secondary APS or SLE-APS. Furthermore, it was recently found that mycophenolatemofetil acts as corticosteroids and as cyclophosphamide sparing agent. Although there is no specific therapy for cytopenias in SLE, corticosteroids remain the mainstay in the treatment of these patients along with less used other conventional treatment options such as azathioprine, cyclophosphamide and human normal immunoglobulin. There are other novel therapies such as thrombopoietin receptor agonists in thrombocytopenia and the use of autologous hematopoitic stem cells transplantation in refractory SLE-APS that are under review. Some of these therapies include thrombopoietin receptor agonists in thrombocytopenia and the use of autologous hematopoitic stem cells transplantation in refractory SLE-APS. The study concludes that treatment of hematological abnormalities is challenging because the treatment itself can cause undue complications sometimes such as granulocytosis due to infection or the use of high doses of steroids and may occur during acute exacerbations of SLE. It is important to take these factors into consideration for disease therapy and management.

Abstract
Although acquired bone marrow failure (BMF) is considered a T cell-mediated autoimmune disease, possible innate immune defects as a cause for systemic immune deviations in response to otherwise innocuous infections have not been extensively explored. In this regard, we recently demonstrated an important role of type I IFNs in protecting hematopoiesis during systemic stress responses to the opportunistic fungal pathogen Pneumocystis in lymphocyte-deficient mice. Mice deficient in both lymphocytes and type I IFN receptor (IFrag(-/-) mice) develop rapidly progressing BMF due to accelerated bone marrow (BM) cell apoptosis associated with innate immune deviations in the BM in response to Pneumocystis lung infection. However, the communication pathway between lung and BM eliciting the induction of BMF in response to this strictly pulmonary infection has been unclear. In this study, we report that absence of an intact type I IFN system during Pneumocystis lung infection not only causes BMF in lymphocyte-deficient mice but also transient BM stress in lymphocyte-competent mice. This is associated with an exuberant systemic IFN-γ response. IFN-γ neutralization prevented Pneumocystis lung infection-induced BM depression in type I IFN receptor-deficient mice and prolonged neutrophil survival time in BM from IFrag(-/-) mice. IL-1β and upstream regulators of IFN-γ, IL-12, and IL-18 were also upregulated in lung and serum of IFrag(-/-) mice. In conjunction, there was exuberant inflammasome-mediated caspase-1 activation in pulmonary innate immune cells required for processing of IL-18 and IL-1β. Thus, absence of type I IFN signaling during Pneumocystis lung infection may result in deregulation of inflammasome-mediated pulmonary immune activation, causing systemic immune deviations triggering BMF in this model.

Abstract
OBJECTIVES Toll-like receptors (TLRs) essential in the functioning of the immune system have been implicated in the development of autoimmunity. TLR3, 7, 8 and 9 are capable of recognizing nucleic autoantigens typical of SLE. Their expression correlates positively with disease activity in adult-onset SLE. This study aimed to determine the role of TLRs in JSLE and whether apoptotic neutrophils are a source of nuclear autoantigen being detected through TLR3, 7, 8 and 9, leading to an inflammatory response. METHODS TLR3, 7, 8 and 9 mRNA and protein expression were measured in peripheral blood mononuclear cells (PBMCs) in JSLE patients compared with JIA and non-inflammatory controls. Activation of the TLRs by JSLE serum-induced apoptotic neutrophils was detected by measuring IFN-α mRNA and protein expression, and confirmed using myeloid differentiation factor 88 (MyD88) and TIR domain-containing adapter-inducing IFN-β (TRIF) inhibitors. RESULTS JSLE patients have increased TLR3, 8 and 9 mRNA and protein expression compared with controls (P < 0.05). Incubation of PBMCs with apoptotic neutrophils demonstrated a dose-response relationship for IFN-α mRNA expression. Inhibition of TLR signalling by blocking MyD88 and TRIF signalling decreased IFN-α mRNA expression in PBMCs incubated with apoptotic neutrophils (P < 0.05). CONCLUSIONS This study demonstrated significantly increased TLR expression in JSLE compared with controls. Our data indicate that apoptotic neutrophils trigger TLR activation through their presentation of autoantigens. The role of TLRs in this inflammatory response was demonstrated by a dose-response relationship to apoptotic neutrophil concentration and confirmed by a decrease in IFN-α production after inhibition of TLR signalling.

Abstract
Death Receptor 5 (DR5) induces apoptosis in various types of cells and is a potential therapeutic target. We have investigated whether targeting DR5 could be used to eliminate pathogenic B lymphocytes from systemic lupus erythematosus (SLE) patients. We examined DR5 expression and function on B lymphocytes from healthy controls subjects, SLE patients, and human tonsil. DR5 was expressed similarly on all B cell subpopulations, including resting and activated B cells. Expression of DR5 was equivalent on B cells from SLE patients and healthy subjects. Additionally, DR5 expression was unchanged after B lymphocyte stimulation. However, B cells were resistant to DR5-induced apoptosis, including after in vitro activation. No changes in subsets of B cells were observed in subjects of a trial of CS-1008, an agonist anti-DR5. While DR5 shows promise as a way to selectively eliminate tumor cells and activated synoviocytes, these data suggest DR5 alone cannot be used as a target to remove pathogenic SLE B cells.

Abstract
Autoimmune neutropenia, caused by neutrophil-specific autoantibodies is a common phenomenon in autoimmune disorders such as Felty's syndrome and systemic lupus erythematosus. Felty's syndrome is associated with neutropenia and splenomegaly in seropositive rheumatoid arthritis which can be severe and with recurrent bacterial infections. Neutropenia is also common in systemic lupus erythematosus and it is included in the current systemic lupus classification criteria. The pathobiology of the autoimmune neutropenia in Felty's syndrome and systemic lupus erythematosus is complex, and it could be a major cause of morbidity and mortality due to increased risk of sepsis. Treatment should be individualized on the basis of patient's clinical situation, and prevention or treatment of the infection. Recombinant human granulocyte colony-stimulating factor is a safe and effective therapeutic modality in management of autoimmune neutropenia associated with Felty's syndrome and systemic lupus erythematosus, which stimulates neutrophil production. There is a slight increased risk of exacerbation of the underlying autoimmune disorder, and recombinant human granulocyte colony-stimulating factor dose and frequency should be adjusted at the lowest effective dose.

Abstract
Recent in vitro studies provide evidence for autoantibody-induced suppression of megakaryocytopoiesis and show a reduction in megakaryocyte production and maturation in the presence of immune thrombocytopenia (ITP) plasma. Here, we present CD34(+) cells from healthy umbilical cord blood mononuclear cells cultured in medium containing thrombopoietin, stem cell factor, interleukin-3, and 10% plasma from either ITP patients or healthy subjects. The quantity, quality, and apoptosis of megakaryocytes were measured. We observed that most ITP plasma boosted megakaryocyte quantity but impaired quality, resulting in significantly less polyploidy cells (N ≥ 4) and platelet release. In these megakaryocytes, we found a lower percentage of cell apoptosis, a lower expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), and a higher expression of Bcl-xL. Furthermore, there was a decrease of sTRAIL in ITP plasma and in cell culture supernatants of this group compared with the control group. Our findings suggest that decreased apoptosis of megakaryocytes also contributes to in vitro dysmegakaryocytopoiesis and reduced platelet production. The abnormal expression of sTRAIL in plasma and TRAIL and Bcl-xL in megakaryocytes may play a role in the pathogenesis of impaired megakaryocyte apoptosis in ITP.

Abstract
We have previously reported that TRAIL is upregulated on T cells from patients with lupus and that T cell associated TRAIL enhances autoimmune parameters in a murine model of lupus. Whether TRAIL/TRAIL-R interaction plays a role in organ involvement such as lupus nephritis has not yet been assessed. We demonstrate here that TRAIL, DR4 and DR5 are upregulated in proximal and distal tubules of patients with proliferative lupus nephritis. In vitro, expression of TRAIL, DR4 and DR5 on primary proximal tubular epithelial cells (PTEC) was induced by TNFalpha and IFNgamma. Functionally, TRAIL did not induce apoptosis but rather enhanced the proliferation of PTEC through activation of PI3 kinase/AKT and ERK1/2, increased IL-8 production and upregulated ICAM-1 expression. These data demonstrate that cytokine induced upregulation of TRAIL, DR4 and DR5 in tubules from patients with proliferative lupus nephritis may play a protective role by enhancing PTEC survival while also exerting a proinflammatory effect that may contribute to local inflammation and injury.

Abstract
Neutrophil constitutive death is a critical cellular process for modulating neutrophil number and function, and it plays an essential role in neutrophil homeostasis and the resolution of inflammation. Neutrophils die due to programmed cell death or apoptosis. In this article, we review recent studies on the mechanism of neutrophil apoptosis. The involvement of caspase, calpain, reactive oxygen species, cellular survival/death signaling pathways, mitochondria, and BCL-2 family member proteins are discussed. The fate of neutrophils can be influenced within the inflammatory microenvironment. We summarize the current understanding regarding the modulation of neutrophil apoptotic death by various extracellular stimuli such as proinflammatory cytokines, cell adhesion, phagocytosis, red blood cells, and platelets. The involvement of neutrophil apoptosis in infectious and inflammatory diseases is also addressed.

Abstract
15-Deoxy-Delta(12,14)-prostaglandin J(2) (15d-PGJ(2)) is a cyclopentenonic prostaglandin endowed with powerful anti-inflammatory activities, as shown in animal models of inflammatory/autoimmune diseases, where pharmacological administration of this prostanoid can ameliorate inflammation and local tissue damage via activation of the nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) and/or covalent modifications of cellular proteins. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF superfamily expressed in most of the cells, including those of immune system such as T lymphocytes, in which it is up-regulated upon antigen-specific stimulation. This cytokine plays an important role in regulating various physiological and immunopathological processes, such as immunosurveillance of tumors and tissue destruction associated with different inflammatory and autoimmune diseases. Here, we demonstrate that 15d-PGJ(2) inhibits trail mRNA and protein expression by down-regulating the activity of its promoter in human T lymphocytes. Our data indicate that both the chemically reactive cyclopentenone moiety of 15d-PGJ(2) and the activation of PPARgamma may be involved in this repressive mechanism. We identified nuclear factor kappaB (NF-kappaB) as a direct target of the prostanoid. 15d-PGJ(2) significantly decreases the expression and/or DNA binding of c-rel, RelA, and p50 transcription factors to the NF-kappaB1 site of trail promoter. Moreover, 15d-PGJ(2)-mediated activation of the transcription factor heat shock factor-1 may contribute to inhibit trail promoter activity in transfected Jurkat T cells. These results suggest that modulation of TRAIL gene expression by 15d-PGJ(2) in T cells may provide a novel pharmacological tool to modify the onset and the progression of specific autoimmune and inflammatory disorders.

Abstract
It is recently suggested that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is involved in the pathogenesis of systemic lupus erythematosus (SLE). In this study, we examined whether expression levels of TRAIL depend on SLE activity. To estimate TRAIL mRNA expression levels in peripheral blood mononuclear cells (PBMC), we performed quantitative real-time reverse transcription-polymerase chain reaction analyses of PBMC from 18 SLE patients and 20 healthy subjects. Serum soluble TRAIL (sTRAIL) concentrations were measured by an enzyme-linked immunosorbent assay. The mean TRAIL mRNA expression level and serum sTRAIL concentration in SLE patients were significantly higher than those in healthy controls. Expression levels of TRAIL mRNA correlated with the SLE disease activity index and circulating immune complexes levels, while serum sTRAIL concentrations did not. These results indicate that increased expression of TRAIL mRNA in PBMC closely correlates with SLE activity and suggest an important role for TRAIL in the pathogenesis of SLE.

Abstract
Churg-Strauss syndrome (CSS) is a rare form of systemic vasculitis occurring in patients with asthma and hypereosinophilia; however, its mechanisms involved in the severe tissue inflammation with vasculitis are poorly understood. High mobility group box 1 (HMGB1) protein, originally identified as a DNA binding protein, also has potent pro-inflammatory and proangiogenic properties. In this study, we hypothesized that HMGB1 might be associated with CSS, and examined serum HMGB1 levels and compared those of asthma patients and healthy volunteers. We also investigated HMGB1 expression in the lesion, and eosinophil HMGB1 amount in CSS patients. We found that the serum HMGB1 levels in CSS patients were significantly higher than those of asthma patients and healthy volunteers. Eosinophils in the CSS lesion expressed HMGB1 and HMGB1 level in eosinophils from CSS patients was significantly higher than that of asthma patients, while there was no significant difference in HMGB1 levels in peripheral mononuclear cells. The serum HMGB1 level in CSS patients decreased after the steroid therapy, and showed significant positive correlations with several molecules, including soluble interleukin-2 receptor, soluble thrombomodulin, and eosinophil cationic protein in sera. We propose that HMGB1 might contribute to the pathogenesis of CSS.

Abstract
OBJECTIVE To evaluate the incidence of electrocardiographic and laboratory abnormalities in neonates born from mothers with connective tissue disease and positive for anti-SSA/Ro antibodies. STUDY DESIGN Electrocardiogram, blood cell counts, liver and renal function tests prospectively obtained from 51 infants born from anti-SSA/Ro-positive mothers with connective tissue disease were compared with those obtained from 50 control infants born from mothers with anti-extractable nuclear antigen (ENA)-negative connective tissue disease. One infant with congenital complete heart block was excluded from analysis. RESULTS No infant showed sinus bradycardia. A first-degree atrioventricular block at birth was observed in five study group and no control group infants, P=0.023. Atrioventricular blocks spontaneously reverted or remained stable during the first year of life. Mean corrected QT value of infants born from anti-SSA/Ro-positive mothers was slightly prolonged as compared with the control group (0.404+/-0.03 s vs 0.395+/-0.02 s; P=0.060). CONCLUSIONS Infants exposed to anti-SSA/Ro antibodies had a significantly higher prevalence of first-degree atrioventricular block. At variance with previous studies, we observed a low frequency of hematologic abnormalities and no cases of hepatobiliary disease.

Abstract
OBJECTIVE Prolonged survival of eosinophils plays an important role in the pathogenesis of Churg-Strauss syndrome (CSS); however, its detailed molecular mechanism is still unclear. TRAIL and its receptors are expressed on a variety of cells, including eosinophils. In this study, we examined the expression of TRAIL receptors on eosinophils from patients with CSS. METHODS TRAIL receptor expression was assessed on eosinophils from healthy volunteers, patients with CSS, patients with asthma, and patients with hypereosinophilia due to parasitic infection. TRAIL-induced apoptosis of eosinophils was compared between the patients with CSS and patients with asthma. RNA interference was used to assess the effects of suppression of TRAIL receptor 3. RESULTS Expression of TRAIL receptor 3, a decoy receptor that acts as an antiapoptotic receptor, on eosinophils from patients with CSS was significantly higher than that in the other subjects. Moreover, in CSS, serum TRAIL receptor 3 levels showed a significant positive correlation with peripheral eosinophil counts, tissue-infiltrating eosinophils stained positive for this receptor, and peripheral T cells expressed TRAIL on their surface. Compared with asthma patients, eosinophils from CSS patients showed a significantly lower percentage of recombinant TRAIL, less autologous T cell-induced apoptosis, and decreased level of active caspase 3. Suppression of TRAIL receptor 3 through RNA interference significantly increased the recombinant TRAIL-induced apoptosis of eosinophils from CSS patients. CONCLUSION Increased expression of TRAIL receptor 3 on eosinophils from patients with CSS was observed. These alterations in TRAIL receptor 3 expression might be involved in the molecular pathogenesis of CSS eosinophilia.

Abstract
T cells play an essential role in driving humoral autoimmunity in lupus. Molecules such as TRAIL exhibit strong T cell modulatory effects and are up-regulated in lupus, raising the possibility that they may influence disease severity. To address this possibility, we examined the role of TRAIL expression on pathogenic T cells in an induced model of murine lupus, the parent-into-F(1) (P-->F(1)) model of chronic graft-vs-host disease (GVHD), using wild-type or TRAIL-deficient donor T cells. Results were compared with mice undergoing suppressive acute GVHD. Although chronic GVHD mice exhibited less donor T cell TRAIL up-regulation and IFN-alpha-inducible gene expression than acute GVHD mice, donor CD4(+) T cell TRAIL expression in chronic GVHD was essential for sustaining effector CD4(+) Th cell numbers, for sustaining help to B cells, and for more severe lupus-like renal disease development. Conversely, TRAIL expression on donor CD8(+) T cells had a milder, but significant down-regulatory effect on CTL effector function, affecting the perforin/granzyme pathway and not the Fas ligand pathway. These results indicate that, in this model, T cell-expressed TRAIL exacerbates lupus by the following: 1) positively regulating CD4(+) Th cell numbers, thereby sustaining T cell help for B cells, and 2) to a lesser degree by negatively regulating perforin-mediated CD8(+) CTL killing that could potentially eliminate activated autoreactive B cells.

Abstract
To investigate the role of neutrophil apoptosis in the pathogenesis of chronic neutropenia, we examined constitutive and death receptor-mediated apoptosis ex vivo of peripheral blood neutrophils obtained from six chronic idiopathic neutropenia (CIN) patients and six healthy adult blood donors. Apoptosis was quantified based on phosphatidylserine externalization and caspase-3 activation in freshly isolated neutrophils or after overnight cultivation of neutrophils in the absence or presence of pro- or anti-apoptotic factors, including the pan-caspase inhibitor, zVAD-fmk. Neutrophils from CIN patients receiving treatment with granulocyte colony-stimulating factor appeared to be more prone to constitutive apoptosis than cells from untreated patients; however, further investigations in larger cohorts of patients are needed to validate these pilot studies. Overall, the level of neutrophil apoptosis was similar in patient and control groups, thus supporting the notion that the underlying defect in these neutropenia patients lies elsewhere, such as in the bone marrow microenvironment.

Abstract
Churg-Strauss syndrome (CSS) is a systemic disease that shows marked eosinophilia along with eosinophil infiltration in the tissue. Prolonged eosinophil survival plays an important role in the pathogenesis of CSS; however, its detailed molecular mechanism remains unclear. Discoidin domain receptor 1 (DDR1) is a receptor tyrosine kinase, and its ligand is collagen. DDR1 was expressed in human leukocytes and fibroblasts, and it plays an important role in leukocyte cytokine production and fibroblast survival in an NF-kappaB-dependent manner. In this study, we examined in vitro and in vivo eosinophil DDR1 expression and its function in CSS patients. The expression level of DDR1 was significantly higher in the eosinophils of CSS patients, and the predominant isoform was DDR1b. Immunohistochemical findings revealed that the tissue-infiltrating eosinophils expressed endogenous DDR1. In CSS patients, DDR1 activation inhibited Fas agonistic antibody-induced apoptosis and up-regulated Fas agonistic antibody-induced cytokine production of eosinophils in an NF-kappaB-dependent manner. Suppression of DDR1 expression in the eosinophils by using RNA interference and addition of the DDR1-blocking protein abolished these effects. We propose that DDR1 contributes to the eosinophil survival in the tissue microenvironment of CSS and that it might be involved in the development of CSS.

Abstract
Discoidin domain receptor 1 (DDR1) is a receptor tyrosine kinase whose ligand is collagen. Recently, we have reported the association of DDR1 in the cytokine production of human leukocytes in in vitro and in vivo expression in idiopathic pulmonary fibrosis. However, its role in in vivo inflammation has not been fully elucidated. Small interference RNA (siRNA) can induce specific suppression of in vitro and in vivo gene expression. In this study, using a bleomycin-induced pulmonary fibrosis mouse model, we administered siRNA against DDR1 transnasally and evaluated histological changes, cytokine expression, and signaling molecule activation in the lungs. Histologically, siRNA against DDR1 successfully reduced in vivo DDR1 expression and attenuated bleomycin-induced infiltration of inflammatory cells. Furthermore, it significantly reduced inflammatory cell counts and concentrations of cytokines such as MCP-1, MIP-1alpha, and MIP-2 in bronchoalveolar lavage fluid. Subsequently, bleomycin-induced up-regulation of TGF-beta in bronchoalveolar lavage fluid was significantly inhibited, and collagen deposition in the lungs was reduced. Furthermore, siRNA against DDR1 significantly inhibited bleomycin-induced P38 MAPK activation in the lungs. Considered together, we propose that DDR1 contributes to the development of bleomycin-induced pulmonary inflammation and fibrosis.

Abstract
Microscopic polyangiitis (MPA) is a systemic necrotizing vasculitis that affects small vessels, resulting in a wide spectrum of organ involvement including the lungs. However, there are little serological markers that predict its prognosis or severity of pulmonary involvement. Vascular endothelial growth factor (VEGF) is an angiogenic mediator, which has been reported to be elevated in systemic vasculitis. In this study, we measured serum VEGF levels in 22 MPA patients with pulmonary involvement. We also investigated VEGF expression in pulmonary cells using flow cytometry analysis. We found that serum VEGF levels in MPA patients were significantly higher than those in respiratory or urinary tract infection. The serum VEGF levels decreased in parallel with the improvement of MPA symptoms. The serum VEGF levels in MPA patients who died within 5 years were significantly higher than those who survived more than 5 years. The sensitivity of VEGF levels to distinguish MPA patient with poor prognosis from those with good prognosis was 90.9%, and specificity was 81.8% (cutoff value = 802.5 pg/ml). The serum VEGF levels showed significant positive correlation with the composite physiological index, which indicates the severity of pulmonary lesion. In flow cytometry analysis, CD11b positive bronchoalveolar lavage fluid cells expressed VEGF. Immunohistochemically, alveolar macrophages, tissue infiltrating inflammatory cells and alveolar epithelial cells stained positive for VEGF. Measurement of serum VEGF levels in MPA might become one of the markers for prognosis and the severity of pulmonary involvement in MPA. VEGF might contribute to the development of pulmonary lesion of MPA.

Abstract
Apoptosis, programmed cell death, of neutrophil and eosinophil granulocytes is a potential control point in the physiological resolution of innate immune responses. There is also increasing evidence that cellular processes of apoptosis can be dysregulated by pathogens as a mechanism of immune evasion and that delayed apoptosis, resulting in prolonged inflammatory cell survival, is important in persistence of tissue inflammation. The identification of cell-type specific pathways to apoptosis may allow the design of novel anti-inflammatory therapies or agents to augment the innate immune responses to infection. This review will explore the physiological roles of granulocyte apoptosis and their importance in infectious and non-infectious lung disease.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disorder that affects various organs and systems. Increased apoptosis, together with defects in the uptake of apoptotic bodies, are thought to have a pathogenic role in SLE. By detection of chromatin condensation, 30% of apoptosis was detected in peripheral blood mononuclear cells (PBMC) from Thai patients with active SLE. Therefore, understanding of the molecular processes in PBMC apoptosis may allow us to gain insight into pathophysiology of SLE. Thus, genes involved in the apoptosis of PBMC from these patients were investigated ex vivo by cDNA array analysis. Seventeen apoptosis-related genes were stimulated in active SLE, more than twofold higher than in inactive SLE. These genes are classified into six groups, namely death receptors, death ligands, caspases, bcl-family, and neutral proteases and genes involved in endoplasmic reticulum stress-mediated apoptosis, such as caspase-4 and GADD153. Among those stimulated genes, tumor necrosis factor (TNF) and the TNF-receptor family were drastically up-regulated 60- and 19-fold higher than in healthy controls, respectively. Moreover, the degree of apoptosis correlated with the level of TNF-alpha in plasma, suggesting that the TNF family plays a role in the induction of apoptosis in SLE. To verify this hypothesis, PBMC from healthy individuals were treated with plasma from active SLE patients in the presence or absence of etanercept, a TNF inhibitor. In the presence of etanercept, active SLE plasma reduced the level of apoptosis to 26.43%. In conclusion, massive apoptotic death of PBMC occurred during the active stage of SLE. The molecular pathway of SLE-PBMC apoptosis was mediated at least via TNF/TNFR signaling pathway, which was confirmed by functional test of TNF-alpha in SLE patients' plasma.

Abstract
The regulation of death pathways in neutrophils has been of long interest, but the relevance of neutrophil apoptosis to the pathogenesis and treatment of autoimmune diseases has only recently been becoming recognized. This brief review addresses the relevant pathways by which neutrophil apoptosis is regulated and summarizes the current understanding regarding the potential role of apoptotic neutrophils in the initiation and/or propagation of autoimmunity, as well as the applicability of modulation of neutrophil death in the treatment of autoimmune diseases.

Abstract
Apoptosis has been attributed an essential role in dilated cardiomyopathy (DCM) recently. We assessed expression of TNF-related apoptosis-inducing ligand (TRAIL) and its decoy receptor osteoprotegerin (OPG) in men with nonischemic DCM, who underwent coronary angiography and endomyocardial biopsy (EMB) after exclusion of coronary artery disease compared to control patients. TRAIL plasma concentrations were elevated in DCM (p=0.02 vs. controls), and were positively correlated with left ventricular enddiastolic diameter (r=0.15, p=0.04), whereas OPG plasma levels did not differ between both groups (p=0.96). In EMB of DCM patients, TRAIL and OPG protein were detected by immunohistochemistry but not in controls. Furthermore, gene expression in EMB or peripheral blood leukocytes (PBL) of DCM patients assessed by real-time PCR showed an increase of TRAIL mRNA in PBL (p=0.01 vs. controls), whereas OPG mRNA was upregulated in endomyocardial specimens (p<0.001 vs. controls). In conclusion, myocardial overexpression of antiapoptotic OPG in DCM patients may represent a compensatory mechanism to limit systemic activation of TRAIL in patients with congestive heart disease.

Abstract
Increased expression of TRAIL in membrane-bound and soluble form in patients with systemic lupus erythematosus (SLE) has been previously reported. In this study, we characterized the upregulation of T-cell-associated and soluble TRAIL (sTRAIL) in vivo and the modulation of TRAIL expression and soluble protein release in vitro following T cell activation and IFNalpha exposure. The expression of membrane-bound TRAIL as determined by flow cytometry was higher on CD4(+) and CD8(+) T cells from lupus patients compared to controls, particularly on activated CD69(+)CD8(+) T cells. Similarly, sTRAIL levels determined by ELISA were significantly elevated in serum from patients with active SLE and correlated with levels of IFNalpha. In vitro, both T-cell-associated and sTRAIL were maximally induced by T cell activation plus IFNalpha in patients and controls. By Western blot analysis, sTRAIL was detected in sera in both the monomeric and multimeric, functional form. Both forms of TRAIL were functional in vitro as determined by Annexin V staining and (51)Cr release assay but the apoptotic activity of membrane TRAIL was 2.5-fold higher compared to that of sTRAIL. These results indicate that IFNalpha-induced enhancement of TRAIL expression and of TRAIL-mediated apoptosis may amplify the abnormal apoptotic process in SLE.

Abstract
Neutrophils are versatile cells, which play a role, not only in inflammatory processes but also in immune and antitumoral responses. Recently, we have reported that interferon (IFN)-activated neutrophils are able to release biologically active tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL/APO2 ligand), a molecule exerting selective, apoptotic activities toward tumor and virus-infected cells, as well as immunoregulatory functions on activated T lymphocytes. Herein, we show that only a minor fraction of the total TRAIL, newly synthesized by IFN-activated neutrophils within 24 h, is released outside, the rest being retained intracellularly, mainly in secretory vesicles and light membrane fractions. We demonstrate that the intracellular pool of TRAIL present in IFN-pretreated neutrophils is rapidly mobilizable to the cell surface and can be secreted following exposure to proinflammatory mediators such as TNF-alpha, lipopolysaccharide, formyl-methionyl-leucyl-phenylalanine, CXC chemokine ligand 8/interleukin-8, insoluble immunocomplexes, and heat shock protein Gp96. These various proinflammatory agonists functioned as effective secretagogue molecules only, in that they failed to augment TRAIL mRNA expression or TRAIL de novo synthesis in freshly isolated neutrophils or cultured with or without IFN. In addition, supernatants from IFN-treated neutrophils stimulated with proinflammatory mediators induced the apoptosis of target cells more effectively than supernatants from neutrophils activated with IFNs alone. Collectively, our results uncover a novel mechanism, whereby the release of soluble TRAIL by neutrophils can be greatly amplified and further reinforce the notion that neutrophils are important cells in tumor surveillance and immunomodulation.

Abstract
The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis of many transformed but also of non-transformed cells. In addition, TRAIL receptor activation has been reported to activate non-apoptotic signaling pathways. Here, we report an increased expression of TRAIL in peripheral blood T cells and monocytes from patients with atopic dermatitis (AD) compared with control individuals. High TRAIL expression was also observed in skin-infiltrating T cells of AD patients. Topical tacrolimus treatment reduced the total number of T cells in the skin, but the relative proportion of TRAIL-positive cells within both CD4+ and CD8+ cell populations did not change. TRAIL was demonstrated to induce the expression of interleukin-1 receptor antagonist (IL-1Ra) in keratinocytes in a caspase-independent manner in vitro. Moreover, increased expression of IL-1Ra was observed in keratinocytes of AD lesional skin. These data suggest that TRAIL-expressing inflammatory skin cells may contribute to the epidermal activation of the IL-1Ra gene in AD.

Abstract
The prognosis of sarcoidosis with pulmonary infiltrates differs in each case, and several cytokines are reported to contribute to its deterioration. However, the detailed mechanism has not been fully elucidated. Discoidin domain receptor 1 (DDR1) is a receptor tyrosine kinase activated by collagen and associated with cytokine production from inflammatory cells. We previously reported the functional expression of DDR1 on CD14-positive bronchoalveolar lavage fluid (BALF) cells in vivo. In this study, we hypothesized that DDR1 might be associated with the deterioration of pulmonary sarcoidosis (PS), and investigated 33 patients with sarcoidosis with pulmonary infiltrates, prospectively. We found that patients with deteriorated PS showed significantly higher DDR1 expression in CD14-positive BALF cells predominant with DDR1b isoforms. Activation of DDR1 induced monocyte chemoattractant protein-1 (MCP-1) and matrix metalloproteinase-9 (MMP-9) production in a p38 mitogen-activated protein kinase-dependent manner from CD14-positive BALF cells of patients with deteriorated sarcoidosis. DDR1 activation also induced NF-kappaB nuclear translocation in CD14-positive BALF cells of patients with deteriorated PS. The inhibitor of NF-kappaB inhibited the production of MCP-1 and MMP-9. We propose that DDR1 is associated with the deterioration of pulmonary sarcoidosis.

Abstract
Chronic idiopathic neutropenia of adults (CINA) is a granulocytic disorder characterised by the "unexplained" decrease in the number of circulating neutrophils. Serum inflammatory cytokines and chemokines are increased in CINA. In addition, cytokines gene polymorphisms are associated with increased levels of respective products and related with inflammatory diseases. The aim of the present study was to investigate the association of polymorphisms of IL1B-511C/T and +3953C/T, IL1RN intron 2, IL6-174G/C and TNF-308G/A genes with CINA. We analysed 29 CINA and controls by polymerase chain reaction and restriction fragment length polymorphism. Statistical analyses were performed using chi2 test, and the Hardy-Weinberg equilibrium (HWE) was investigated. All alleles analysed were in HWE in both populations. Similar frequencies of IL1B-511C/T, IL1B+3953C/T, IL1RN, IL6-174G/C and TNF-308G/A genotypes were observed in CINA and controls. These results suggest that cytokine polymorphisms associated with control of gene expression and protein levels were not associated with occurrence of CINA and were not responsible for the increased cytokine in CINA patients.

Abstract
Discoidin domain receptor 1 (DDR1) is a receptor tyrosine kinase activated by collagen. We previously reported the functional expression of DDR1 on human monocyte-derived macrophages in vitro; however, information regarding its role in diseases is limited. Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease, and the lesions contain an abundance of collagen. In this study, we examined DDR1 expression on bronchoalveolar lavage fluid (BALF) cells and investigated its functionality using samples obtained from 28 IPF patients, 13 chronic obstructive pulmonary disease patients, and 14 healthy volunteers. The DDR1 expression level in CD14-positive BALF cells was higher in IPF patients than in chronic obstructive pulmonary disease patients or healthy volunteers. The predominant isoform was DDR1b in the IPF group, while DDR1a was predominant in the other two groups. Using immunohistochemical analysis, we also detected DDR1 expression on infiltrating inflammatory cells in the IPF lesion. In IPF patients, DDR1 activation induced the production of MCP-1, IL-8, MIP-1 alpha, and matrix metalloproteinase-9 (MMP-9) from CD14-positive BALF cells in a p38 MAPK-dependent manner. In contrast, DDR1 activation of CD14-positive BALF cells in the other groups did not induce the production of these chemokines or MMP-9. These chemokines and MMP-9 contribute to the development of IPF and, therefore, we suggest that DDR1 might be associated with the pathogenesis of IPF in the tissue microenvironment.

Abstract
BACKGROUND Increased apoptosis may induce autoimmune conditions. Apoptosis is induced by binding of death receptor ligands, members of the tumour necrosis factor (TNF) superfamily, to their cognate receptors. The Fas-Fas ligand pathway has been studied extensively in relation to systemic lupus erythematosus (SLE). However, other death pathways are also considered important. TNF related apoptosis inducing ligand (TRAIL), another ligand of the TNF superfamily, induces apoptosis in sensitive cells. OBJECTIVE To assess soluble (s) TRAIL concentrations in sera of SLE patients. METHODS 40 SLE patients were studied (20 with active and 20 with inactive disease). Serum sTRAIL concentrations were measured by a solid phase sandwich enzyme linked immunosorbent assay. Levels in SLE patients were compared with those in patients with rheumatoid arthritis (n = 20), Wegener's granulomatosis (n = 20), and healthy controls (n = 20). RESULTS Mean (SEM) serum sTRAIL concentration in SLE patients (936.0 (108.2) pg/ml) was higher than in healthy controls (509.4 (33.8) pg/ml; p<0.01) or in disease control patients with rheumatoid arthritis (443.8 (36.1) pg/ml, p<0.001) or Wegener's granulomatosis (357.1 (32.2) pg/ml; p<0.001). The mean serum sTRAIL concentration was 1010.2 (168.0) pg/ml for patients with inactive disease and 861.8 (138.7) pg/ml for those with active disease. sTRAIL values were not correlated with specific manifestations of the disease, such as leucopenia or lymphopenia, or with SLE disease activity index. CONCLUSIONS Serum sTRAIL concentrations are increased SLE patients. This seems to be disease specific and could indicate a role for TRAIL in SLE pathophysiology.
