Abstract
Autoimmune diseases have a prevalence of approximately 7 to 9% and are classified as either organ-specific diseases, including type I diabetes, multiple sclerosis, inflammatory bowel disease and myasthenia gravis, or systemic diseases, including systemic lupus erythematosus, rheumatoid arthritis and Sjögren's syndrome. While many advancements have been made in understanding of the mechanisms of autoimmune disease, including the nature of self-tolerance and its breakdown, there remain unmet needs in terms of effective and highly targeted treatments. T regulatory cells (Tregs) are key mediators of peripheral tolerance and are implicated in many autoimmune diseases, either as a result of reduced numbers or altered function. Tregs may be broadly divided into those generated in the thymus (tTregs) and those generated in the periphery (pTregs). Tregs target many different immune cell subsets and tissues to suppress excessive inflammation and to support tissue repair and homeostasis: there is a fine balance between Treg cell stability and the plasticity that is required to adjust Tregs' regulatory purposes to particular immune responses. The central role of immunoglobulin E (IgE) in allergic disease is well recognized, and it is becoming increasingly apparent that this immunoglobulin also has a wider role encompassing other diseases including autoimmune disease. Anti-IgE treatment restores the capacity of plasmacytoid dendritic cells (pDCs) impaired by IgE- high-affinity IgE receptor (FcεR1) cross-linking to induce Tregs in vitro in atopic patients. The finding that anti-IgE therapy restores Treg cell homeostasis, and that this mechanism is associated with clinical improvement in asthma and chronic spontaneous urticaria suggests that anti-IgE therapy may also have a potential role in the treatment of autoimmune diseases in which Tregs are involved.

Abstract
Systemic autoimmune and inflammatory diseases have a complex and only partially known pathophysiology with various abnormalities involving all the components of the immune system. Among these components, antibodies, and especially autoantibodies are key elements contributing to autoimmunity. The interaction of antibody fragment crystallisable (Fc) and several distinct receptors, namely Fc receptors (FcRs), have gained much attention during the recent years, with possible major therapeutic perspectives for the future. The aim of this review is to comprehensively describe the known roles for FcRs (activating and inhibitory FcγRs, neonatal FcR [FcRn], FcαRI, FcεRs, Ro52/tripartite motif containing 21 [Ro52/TRIM21], FcδR, and the novel Fc receptor-like [FcRL] family) in systemic autoimmune and inflammatory disorders, namely rheumatoid arthritis, Sjögren's syndrome, systemic lupus erythematosus, systemic sclerosis, idiopathic inflammatory myopathies, mixed connective tissue disease, Crohn's disease, ulcerative colitis, immunoglobulin (Ig) A vasculitis, Behçet's disease, Kawasaki disease, IgG4-related disease, immune thrombocytopenia, autoimmune hemolytic anemia, antiphospholipid syndrome and heparin-induced thrombocytopenia.

Abstract
Antibody-mediated autoimmune diseases (AAID) involve several isotypes of autoreactive antibodies. In a growing number of AAID, autoreactive IgE are present with a significant prevalence and are often associated with the presence of IgG anti-IgE and/or anti-FcεRIα (high affinity IgE receptor α chain). FcεRI-bearing cells, such as basophils or mast cells, are key players in some of these AAID. Recent advances in the pathophysiology of these diseases led to the passed or current development of anti-IgE strategies that showed very potent effects in some of them. The present review centralizes the information on the relevance of autoreactive IgE and FcεRI-bearing cells in the pathophysiology of different AAID and the ones where the anti-IgE therapeutic strategy shows or may show some benefits for the patients.

Abstract
BACKGROUND In most cases of allergic transfusion reactions (ATRs), the causative agents have not been identified and the mechanisms are largely unknown, with a few exceptions. The basophil activation test (BAT) was recently introduced in the field of transfusion to investigate the causal relationships between ATRs and transfusion, as well as the mechanisms behind them. STUDY DESIGN AND METHODS The BAT was used to screen the residual supernatants (SNs) of 43 blood components associated with serious ATRs for those that can activate basophils of many healthy volunteers. The SNs were then fractionated by centrifugal ultrafiltration and protein G column chromatography and each separated fraction was reexamined by the BAT. RESULTS Of the 43 such blood components, one activated basophils from 19 of 21 healthy volunteers. In the blood component, the IgG antibody against IgE was identified as a putative causative agent. CONCLUSION Blood donors who possessed the IgG antibody against IgE may be dangerous to transfusion recipients. The BAT would be useful in identifying such high-risk blood donors, when it is used to screen the blood components associated with serious ATRs for residual SNs that can activate the basophils of many healthy volunteers.

Abstract
Autoantibodies of the IgG subclass are pathogenic in a number of autoimmune disorders such as systemic lupus erythomatosus. The presence of circulating IgE autoantibodies in autoimmune patients has also been known for almost 40 years. Despite their role in allergies, IgE autoantibodies are not associated with a higher rate of atopy in these patients. However, recently they have been recognized as active drivers of autoimmunity through mechanisms involving the secretion of Type I interferons by plasmacytoid dendritic cells (pDC), the recruitment of basophils to lymph nodes, and the activation of adaptive immune responses through B and T cells. Here, we will review the formation, prevalence, affinity, and roles of the IgE autoantibodies that have been described in autoimmunity. We also present novel evidence supporting that triggering of IgE receptors in pDC induces LC3-associated phagocytosis, a cellular process also known as LAP that is associated with interferon responses. The activation of pDC with immune complexes formed by DNA-specific IgE antibodies also induce potent B-cell differentiation and plasma cell formation, which further define IgE's role in autoimmune humoral responses.

Abstract
There is accumulating evidence to suggest that IgE plays a significant role in autoimmunity. The presence of circulating self-reactive IgE in patients with autoimmune disorders has been long known but, at the same time, largely understudied. However, studies have shown that the increased IgE concentration is not associated with higher prevalence for atopy and allergy in patients with autoimmune diseases, such as systemic lupus erythematosus. IgE-mediated mechanisms are conventionally known to facilitate degranulation of mast cells and basophils and promote TH2 immunity, mechanisms that are not only central to mounting an appropriate defense against parasitic worms, noxious substances, toxins, venoms, and environmental irritants but that also trigger exuberant allergic reactions in patients with allergies. More recently, IgE autoantibodies have been recognized to participate in the self-inflicted damaging immune responses that characterize autoimmunity. Such autoimmune responses include direct damage on tissue-containing autoantigens, activation and migration of basophils to lymph nodes, and, as observed most recently, induction of type 1 interferon responses from plasmacytoid dendritic cells. The importance of IgE as a central pathogenic mechanism in autoimmunity has now been clinically validated by the approval of omalizumab, an anti-IgE mAb, for patients with chronic spontaneous urticaria and for the clinical benefit of patients with bullous pemphigoid. In this review we summarize recent reports describing the prevalence of self-reactive IgE and discuss novel findings that incriminate IgE as central in the pathogenesis of inflammatory autoimmune disorders.

Abstract
In systemic sclerosis (SSc) and its variants, autoantibodies are the best known immunological aberration. In more than 95% of the patients, antinuclear antibodies or other autoantibodies can be detected. In about 90% of SSc patients with antinuclear antibodies, scleroderma associated autoantibodies highly specific for systemic sclerosis are found. These autoantibodies usually exclude each other in individual patients, and they are detectable early, persisting during the course of the disease. SSc patients characterized by scleroderma associated autoantibodies belong to disease subsets which are relatively homogeneous in clinical, genetic and prognostic terms. Besides these diagnostically relevant autoantibodies, numerous additional ones have also been described. These are neither SSc specific nor mutually exclusive, and their antigens have only been partially characterized. Some, however, are thought to be relevant to the as yet unanswered question of whether autoantibodies are directly involved in SSc pathogenesis.

Abstract
OBJECTIVE Fibroblasts play a major role in the development of systemic sclerosis (SSc), and the occurrence of serum autoantibodies reacting with fibroblast plasma membrane antigens in SSc has been reported. This study was undertaken to investigate whether IgG from SSc sera that react with human fibroblasts modulates the fibroblasts' function. METHODS Sera from 69 patients with SSc (28 with limited cutaneous SSc [lcSSc] and 41 with diffuse cutaneous SSc [dcSSc]), 30 patients with sarcoidosis, and 50 matched healthy controls were examined. We evaluated antibody binding to human skin and lung fibroblasts by cell-based enzyme-linked immunosorbent assay (ELISA), indirect immunofluorescence, and flow cytometry. We further investigated the ability of purified IgG to modulate 1) intercellular adhesion molecule 1 (ICAM-1) expression, 2) U937 cell adhesion to fibroblasts, and 3) fibroblast steady-state messenger RNA (mRNA) levels of interleukin-1alpha (IL-1alpha), IL-beta, and IL-6, and IL-6 protein production. RESULTS Of 69 SSc sera tested by cell-based ELISA, 58% bound to normal skin and lung fibroblasts. The prevalence of binding was significantly higher in dcSSc than in lcSSc (P < 0.05). Only IgG from SSc sera that were positive for antifibroblast antibody (AFA) induced a dose-dependent up-regulation of ICAM-1 expression and IL-6 production, enhancement of U937 cell adhesion, and increased levels of IL-1alpha, IL-1beta, and IL-6 mRNA in fibroblasts. Up-regulation of ICAM-1 mediated by AFA IgG was inhibited by the addition of IL-1 receptor antagonist, indicating an autocrine activation loop. CONCLUSION Our findings confirm the presence of AFAs in SSc sera and demonstrate, for the first time, that autoantibodies reacting with fibroblast surface molecules act as an extrinsic stimulus inducing fibroblast activation in vitro.

Abstract
Basophil granulocytes and tissue mast cells and their mediators play a role in the pathogenesis of several immune and inflammatory disorders. Human basophils and mast cells (FcepsilonRI+ cells) can be activated through immunological interaction with the IgE-FcepsilonRI network. FcepsilonRI+ cells can be triggered by cross-linking between the Fab portions of IgE and multivalent antigens (direct anaphylaxis). 'Reverse type' anaphylaxis can occur through three distinct mechanisms: antibodies against the Fcepsilon portion of IgE (anti-IgE), antibodies against epitopes of the alpha chain of FcepsilonRI (anti-FcepsilonRIalpha) and anti-IgG acting on IgG-IgE complexes bound to FcepsilonRI. Anti-IgE autoantibodies are occasionally present even in normal donors and more frequently in a variety of allergic (chronic urticaria, atopic dermatitis and bronchial asthma) and autoimmune disorders (rheumatoid arthritis, lupus erythematosus and systemic sclerosis). IgG anti-IgE from a small percentage of patients induces the release of mediators from human FcepsilonRI+ cells. Some of the anti-IgE autoantibodies present in allergic patients are non-anaphylactogenic, thus representing a possible protective mechanism preventing the association of IgE with FcepsilonRI. Anti-FcepsilonRIalpha autoantibodies also occur in a significant percentage of patients of chronic urticaria and probably non-allergic asthma and some autoimmune diseases. Although anti-IgE and anti-FcepsilonRIalpha autoantibodies, present in a percentage of patients with immune disorders, are relevant to the pathogenesis of these conditions, much remains to be learnt about their immunochemistry, their prevalence and precise role in various inflammatory diseases.

Abstract
Scleroderma renal crisis (SRC) was known as a rare and catastrophic syndrome responsible for acute renal failure (ARF) in a context of widespread microvascular disease occurring in progressive systemic sclerosis (PSS). Following pathogenetic hypoteses, angiotensin converting enzyme (ACE) inhibitors, plasma infusions (PI), and plasma-exchange (PE) have been employed in SRC with favorable results. Our purpose was to verify whether these therapies have consistently changed the fatal prognosis of SRC, even in our experience. In the last 10 years, SRC was diagnosed in eight patients (all eight with histologic data). The first five cases were treated with steroids, antihypertensive-cocktail, and PI: all five died, two within 48 hours, three after 10, 15, and 300 days, respectively. Three other patients were treated with ACE inhibitors, PI, and PE: all three died after 1, 9, and 12 months of HD. Clinical-histological correlations showed a strong relationship between the extent of glomerular involvement and the degree of renal failure, while arterial lesions seem to be more related to the past history of PSS, independently from the previous existence of hypertension. We conclude that "true" SRC diagnosed by restrictive criteria is still a rare life-threatening syndrome, and, unfortunately, no clear predictive biochemical or clinical signs could be identified; vascular renal involvement correlates to the duration of PSS independently of previous clinical evidence of renal failure or hypertension; a glomerular pattern similar to that reported for hemolytic-uremic syndrome (HUS)/thrombotic thrombocytopenic purpura (TTP) syndrome is directly related to the degree of acute renal involvement; SRC may occur even in the absence of hypertension, mainly if cardiomyopathy is present: in our experience. ACE inhibitors and plasma therapies have changed the short-time prognosis of SRC, but they may be unable to provide recovery from dialysis and do not avoid further evolution of extrarenal PSS exiting in late death.

Abstract
Eight patients aged between 5 and 26 years developed rapid deterioration of renal function and became oliguric/anuric with duration ranging from 1 to 21 days. The initial functional assessment revealed severe degree of glomerular, tubular, and vascular dysfunctions. The magnitude of renal dysfunction was quantified and expressed in terms of a clinical score. The degree of glomerular and tubular dysfunctions were inversely proportional to the renal plasma flow and peritubular capillary blood flow (PTCB), respectively. Similar findings have been observed in a variety of severe glomerulonephropathies. In this aspect, it is likely that the reduction of peritubular capillary blood flow and tubulointerstitial disease are interrelated. Further evidence to support the primary role of reduction of PTCB in inducing tubulointerstitial disease is provided by the following: (a) Reduction of PTCB is documented in mesangial proliferative nephrosis with steroid resistance prior to the detection of tubulointerstitial disease. (b) Ischemic insult can induce tubulointerstitial disease in experimental setting of renal artery occlusion in animal, (c) Improved tubular function can be achieved following the increase in PTCB with the enhanced renal perfusion therapy.

Abstract
The aim of this study was to evaluate the function of basophil granulocytes in 37 patients with progressive systemic sclerosis (PSS). The in vitro proteinase release test using Chromozyme TH as a chromogenic substrate was performed to measure the basophil cell releasability. Anti-IgE, calcium-ionophore (A 23187) and N-formyl-methyonil-leucyl-phenylalanine were used as activatory agents. Our results showed that the reactivity pattern to those agents did not differ in PSS compared to controls. Patients whose basophil cells release proteinases to all of the 3 activators tended to have more severe organ symptoms compared to the rest of the patients, while teleangiectasia was significantly less frequently (p < 0.02) found in cases with proteinase release. These findings suggest that there may be a certain relationship between basophil function and severity of the PSS.

Abstract
We evaluated basophil releasability in 16 female patients with scleroderma (systemic sclerosis) and in 16 normal age- and sex-matched donors. Basophils from patients with scleroderma released significantly more histamine "spontaneously" than did those from normal donors (12.9 +/- 2.1% versus 4.5 +/- 0.7%; P less than 0.0005). Basophil reactivity (maximal percentage histamine release) to anti-IgE was higher in patients with scleroderma than in controls (57.0 +/- 7.5% versus 35.4 +/- 7.8%; P less than 0.05). Basophil sensitivity (the concentration of anti-IgE that causes 40% of maximal percentage histamine release) to anti-IgE in scleroderma patients was similar to that found in controls (4.6 +/- 2.8 x 10(-2) micrograms/ml versus 2.3 +/- 1.0 x 10(-1) micrograms/ml; P not significant). Scleroderma patients also showed enhanced releasability compared with that of the controls when challenged in vitro with interleukin-3 (8.3 +/- 1.7% versus 3.2 +/- 0.6%; P less than 0.01). Releasability induced by the formyl-containing tripeptide, f-met peptide, was significantly higher in the scleroderma patients than in the controls at the 2 lower concentrations used. No differences in basophil reactivity and sensitivity to f-met peptide and calcium ionophore A23187 were found between patients and normal donors. These results show that spontaneous basophil releasability and releasability in response to IgE cross-linking and activation of interleukin-3 receptors are increased in patients with scleroderma.

Abstract
Paired biopsy samples from involved and uninvolved skin were obtained from 19 patients with generalized scleroderma (11 with early, progressive disease and 8 with late, improving disease). Skin biopsy samples were double stained for mast cell granules and for mast cell membrane. The number of mast cells was increased in patients with systemic sclerosis (SSc), in both involved and uninvolved skin and in both early and late disease. There was an increase in the number of degranulated mast cells in the involved skin of patients with both early and late disease and in the not-yet-involved skin of patients with early disease; however, there was no increase in the number of degranulated mast cells in areas of previously involved but now normal skin of patients with late disease. Increases in mast cell number and degranulation precede clinically apparent dermal fibrosis in SSc. These observations and the absence of mast cell degranulation in regressing skin suggest a participatory role of the mast cell in the clinical progression of skin changes in SSc.
