Autoimmune lymphoproliferative syndrome (ALPS) is characterized by nonmalignant lymphadenopathy, splenomegaly, and autoimmune cytopenias. In 1995, defective lymphocyte apoptosis secondary to mutations in the FAS gene was identified as a molecular basis for ALPS.

The purpose of the protocol is to allow for patients, and relatives of patients, who may have the newly described autoimmune lymphoproliferative syndrome, to be evaluated at the NIH Clinical Center. This evaluation will include blood and relevant tissue studies along with long-term clinical evaluations to define the biology, inheritance,clinical spectrum, and natural history of this syndrome. The aim of the research is to understand mechanisms involved in the development of expanded numbers of what is typically a rare population of immune cells (CD4-8-/TCRalpha/beta+ T cells, otherwise referred to as double negative T cells), and how these relate to the development of expanded numbers of immune cells and autoimmune (self against self) responses in patients with ALPS.. In some cases, we may proivide treatment related to ALPS. These treatments are consistent with standard medical practice.. Participants with ALPS will be invited to visit the NIH once a year or more frequently when clinically ...

This study will evaluate the safety and effectiveness of an antibiotic called Fansidar on autoimmune lymphoproliferative syndrome (ALPS). Patients with ALPS have enlarged lymph glands, spleen and/or liver, abnormal blood cell counts and overactive immune function. Current treatments are aimed at suppressing the immune system and improving symptoms, such as anemia (low red blood cell count) and low white blood cell and platelet counts. These treatments, however, are only partially effective and may have complications. Fansidar is a combination of two drugs, sulfadoxine and pyrimethamine, that is used to treat or prevent parasitic infections such as malaria. Recently a child with ALPS who was treated with Fansidar for a different illness had a marked shrinkage of the lymph organs. This study will examine whether Fansidar can shrink the lymph glands or spleen in patients with ALPS.. Patients with ALPS between the ages of 4 and 70 years who have had lymph gland enlargement for at least 1 year and ...

Treatment is most commonly directed at autoimmune disease and may be needed to treat bulky lymphoproliferation. First line therapies include corticosteroids (very active but toxic with chronic use), and IVIgG, which are not as effective as in other immune cytopenia syndromes. Second line therapies include: mycophenolate mofetil (cellcept)[15] which inactivates inosine monophosphate, most studied in clinical trials with responses varying (relapse, resolution, partial response). It does not affect lymphoproliferation or reduce DNTs, with no drug-drug interactions. This treatment is commonly used agent in patients who require chronic treatment based on tolerance and efficacy. It may cause hypogammaglobulinemia (transient) requiring IVIgG replacement. Sirolimus (rapamycin, rapamune) which is a mTOR (mammalian target of rapamycin) inhibitor[16] can be active in most patients and can in some cases lead to complete or near-complete resolution of autoimmune disease (,90%)[17][18] With this treatment ...

Variants in CASP10 cause autoimmune lymphoproliferative syndrome through a likely dominant negative mechanism. A single report of an exonic deletion leading to a frameshift was reported in one patient with systemic juvenile idiopathic arthritis (Tadaki H et al.). The deletion was inherited from a normal parent. Of note, SNPs polymorphism of CASP10 were found to be associated with risk of gastric cancers, cardia adenocarcinomas, and gastric noncardia adenocarcinomas (PMID 23921907). SNPs loci of CASP10 were also identified associated with susceptibility of chronic lymphocytic leukemia or small lymphocytic lymphoma (PMID 23770605), breast cancer (PMID 23212337), and cutaneous melanoma (PMID 18563783).. ...

Results and conclusions The causes of double-negative T-cell lymphocytosis in children were autoimmune lymphoproliferative syndrome (ALPS) and reactive γ/δ Τ-lymphocytosis. T-cell large granular lymphocyte (T-LGL) leukaemia, reactive γ/δ T-lymphocytosis and hepatosplenic T-cell lymphoma (HSTL) were the the most common disorders underlying double-negative T-cell lymphocytosis in adults. Less common causes included hypereosinophilic syndrome, peripheral T-cell lymphoma, ALPS and monoclonal, double-negative T-lymphocytosis of uncertain significance. CD5/CD7/Vδ2 expression and absolute double-negative lymphocyte count (,1.8×109/L) were useful discriminators for distinguishing patients with reactive γ/δ T-lymphocytosis from those with γ/δ lymphoproliferative disorders. Differentiating between γ/δ T-LGL and HSTL can be difficult. Expression of CD57 and cellular morphology (pale cytoplasm with distinct granules) would support a diagnosis of γ/δ T-LGL. ...

RAS-associated autoimmune leukoproliferative disorder (RALD) is a rare genetic disorder of the immune system. RALD is characterized by lymphadenopathy, splenomegaly, autoimmunity, and elevation in granulocytes and monocytes. It shares many features with autoimmune lymphoproliferative syndrome and is caused by somatic mutations in NRAS or KRAS. This was first described by investigators João Oliveira and Michael Lenardo from the National Institutes of Health. Clinically, RALD is characterized by splenomegaly, a relatively mild degree of peripheral lymphadenopathy, and autoimmunity. The autoimmune phenotype can present in childhood or adulthood and primarily includes autoimmune hemolytic anemia, ITP, and neutropenia. Some patients have a history of recurrent respiratory tract infections. It is unclear if increased risk for malignancy is part of RALD. Importantly, however, the clinical and laboratory phenotype resembles juvenile myelomonocytic leukemia. The high fatality rate of this childhood ...

We report the case of a young woman who developed, 3 years after stopping Rituximab (RTX) prescribed for immune thrombocytopenia (ITP), a severe immunodeficiency leading to fatal pulmonary Epstein–Barr virus-positive diffuse large B-cell lymphoma. Genetic analysis led us to identify four missense mutations known to affect immune-deficiency–associated genes (FAS-ligand (|i|FASL|/i|) gene (p.G167R); perforin-1 (|i|PRF1|/i| (p.R55C) gene; the Bloom syndrome RecQ-Like helicase (|i|BLM|/i|) gene and the Moesin (|i|MSN|/i|) (p.A122T) gene). The heterozygous mutation in the |i|FASL|/i| gene, not present in the Genome Aggregation Database or ClinVar database, could suggest atypical Autoimmune LymphoProliferative Syndrome and its role in this patient’s immunodepression is discussed. This observation strengthens the role of |i|FASL|/i| gene mutation in severe clinical phenotypes of primary immune deficiency and raises new questions about the genetic background of ITP occurring in young people

A fundamental biological question that remains largely unresolved concerns the mechanism by which binding of ligands to receptors on the cell surface causes transmission of a signal through the plasma membrane. One appealing explanation has been that ligand binding brings receptors together into multimeric complexes. Three reports describe cases in which the opposite approach is taken, and the receptors are bound and lie in wait for the ligand. Siegel et al. and Chan et al. have examined how the Fas and tumor necrosis factor (TNF) receptors signal. They define a protein interaction domain in these receptors that mediates assembly of the receptors into complexes in the absence of ligand. Such association is shown to be necessary for ligand binding and subsequent signaling. The results also explain how abnormal forms of Fas can dominantly prevent Fas-induced signaling in the human disease known as autoimmune lymphoproliferative syndrome. When bound to their cognate receptors, interferons (IFNs) ...

Although ALPS is frequently caused by mutations in known genes, such as FAS, FASLG or CASP10, in 20-30% of cases the defect is still unknown. It is highly likely that defects in or overexpression of regulators of these genes such as miR-146a22 could result in an ALPS-like phenotype and account for a not yet defined percentage of ALPS-U cases. In the present study we identified an IL12RB1 mutation and the IL12 signaling pathway as such an alternative cause of an ALPS-like phenotype through regulation of FasL expression. Previously it was shown that activation of T and NK cells by IL12 results in upregulation of FasL.23-26,28,42 For instance, Yu et al. showed that dendritic cell-derived IL12 is involved in upregulation of FasL on NK cells leading to cell death.25 Moreover, in the absence of antigen, IL12 induces apoptosis of T cells via upregulation of FasL which can be blocked by anti-FasL antibodies.26 In line with this, we found that primary human T cells deficient in FasL expression were ...

Background: Mikuliczs disease (MD) has been considered as one manifestation of Sjögrens syndrome (SS). Recently, it has also been considered as an IgG4-related disorder.. Objective: To determine the differences between IgG4-related disorders including MD and SS.. Methods: A study was undertaken to investigate patients with MD and IgG4-related disorders registered in Japan and to set up provisional criteria for the new clinical entity IgG4-positive multiorgan lymphoproliferative syndrome (IgG4+MOLPS). The preliminary diagnostic criteria include raised serum levels of IgG4 (,135 mg/dl) and infiltration of IgG4+ plasma cells in the tissue (IgG4+/IgG+ plasma cells ,50%) with fibrosis or sclerosis.

1. Probably the most famous repurposing case is that of thalidomide. First used as a sedative in the 1950s thalidomide is infamous for causing birth defects in babies of women who were prescribed it to treat nausea whilst pregnant. It was, however, successfully and safely repurposed in 1998 to treat leprosy and in 2006 to treat the blood cancer multiple myeloma.. 2. Discovered in 1972 on Easter Island, rapamycin, also known as Sirolimus, is produced by a soil bacterium Streptomyces hygroscopicus. Its ability to suppress the immune system led to its original approved use to prevent rejection in organ transplantation in 1999. It has since been successfully repurposed to treat two rare diseases, autoimmune lymphoproliferative syndrome (ALPS) and lymphangioleiomyomatosis, a lung disease.. 3. Lomitapide was originally used to lower cholesterol and triglycerides.

X-linked Lymphoproliferative Syndrome - Etiology, pathophysiology, symptoms, signs, diagnosis & prognosis from the MSD Manuals - Medical Professional Version.

Consistent with the finding that Fas deficiency might also alter homeostasis of conventional immune cell lineages independently of Eomes, we found that the autoimmune manifestations of ALPS were not affected by the T cell-specific deletion of Eomes (Fig. 2E, 2F). This result was not unexpected because independent lines of evidence have uncoupled DN T cell accumulation from the pathogenic autoantibody production of ALPS (3, 4, 9). Whereas B cell- or DC-specific deficiency of Fas is not sufficient to drive DN T cell expansion, either is sufficient to recapitulate the autoantibody production of ALPS (3, 4). CD4+ T cells, DCs, and B cells are still present and Fas-deficient in lpr/lpr, Eomes F/F, Cd4:Cre+ mice, providing a sufficient cellular network for the elaboration of pathogenic autoantibodies. Taken together, these data suggest that the Eomes-dependent DN T cell population is responsible for the lymphoproliferative phenotype but does not appear to be required for the humoral autoimmunity ...

Knee diameters were increased in mBSA-injected wt mice compared to PBS-injected controls (3.21 ± 0.2 vs. 2.98 ± 0.1, p , 0.05, t-test), and this increase was not significant in Fas -/- mice (2.97 ± 0.2 vs. 2.87 ± 0.1). Histology revealed presence of synovial hyperplasia in both mBSA-injected groups, but mBSA-injected wt mice had decreased trabecular bone volume in distal femoral metaphyses (BV/TV) compared to controls (1.08 ± 0.57 vs. 2.55 ± 0.43; p , 0.05, t-test). There was no significant difference between mBSA-injected and control group in Fas -/- mice (2.34 ± 0.62 vs. 2.61 ± 0.65). μCT analysis showed that mBSA-injected wt mice had decreased BV/TV (2.99 ± 0.19 v. 1.96 ± 0.19; p , 0.001, t-test) and trabecular number (TbN) (1.03 ± 0.03 vs. 0.64 ± 0.02), as well as increased trabecular separation (TbSep) (256,89 ± 1395,12 vs. 312.40 ± 1323.91), compared to controls. mBSA injected Fas -/- mice had decreased TbN compared to controls (0.815 ± 0.01 vs. 0.64 ± 0.04; p , 0.05, ...

Our analysis of DNTC suggests that they represent a novel suppressor cell population whose function is to negatively regulate immune responses. As DNTC acquire regulatory properties only after exposure to self Ags in vivo, it suggests that a self Ag-driven peripheral expansion plays a pivotal role in the acquisition of immunoregulatory function. Rather than stimulating rapid growth, effector cell formation, and acute activation markers, exposure to cognate Ag initiates DNTC to undergo slow expansion and memory conversion. For instance, DNTC having undergone self Ag-driven peripheral expansion possess markers of T cell memory, a lowered threshold of activation, an ability to rapidly express IFN-γ after TCR stimulation, and ex vivo cytolytic activity. However, DNTC from Ag+ mice differ from conventional T cells or those from Ag− mice in that they respond poorly when challenged with cognate Ag in vitro and fail to synthesize IL-2. As they possess potent cytolytic activity and express cognate Ag, ...

Human X-linked inhibitor of apoptosis (XIAP) protein belongs to a family of apoptotic suppressor proteins that share a conserved motif, the baculovirus IAP repeat (BIR). The BIR motif is necessary for antiapoptotic function. XIAP plays a variety of other functional roles, such as also modulation of inflammatory signaling and immunity, mitogenic kinase signaling, cell proliferation, and copper homeostasis. XIAP acts as a caspase inhibitor by binding to the active site of caspase 3 and 7; it also inactivates caspase 9 by preventing it from forming active homodimers. Mutations in the XIAP gene are associated with X-linked lymphoproliferative syndrome. XIAP is also known as baculoviral IAP repeat-containing 4 (BIRC4), inhibitor of apoptosis protein 3 (IAP3), hIAP3, IAP-like protein, API3, ILP1, MIHA, and XLP2.. ...

LOS ANGELES - For Jacob Martinez, blood and platelet transfusions are part of daily life. So is confinement to a tiny room sealed off from the contaminates of the outside world. Jacob, 5, of Pico Rivera, has been in his clean room for three months, since he received a bone marrow transplant in October. But that transplant failed, and now a second is needed to make it possible for the boy to produce his own blood. This is a hard battle, Jacobs father, Peter Martinez, said. We just stay with him and love him, and make him as comfortable and happy as we can. Jacob suffers from X-linked Lymphoproliferative Syndrome, or XLP, an immune system deficiency. Diagnosed at just a month old, he has been in and out of hospitals his entire life. The disease makes him highly susceptible to infections and could make even mild illness deadly. It affects only boys, and is passed down by female carriers in a family, who display no symptoms. If left untreated, Jacobs life expectancy would be about 10 years. ...

CiteWeb id: 20050000212. CiteWeb score: 2801. DOI: 10.1016/j.immuni.2005.01.016. Regulatory T cell-mediated dominant tolerance has been demonstrated to play an important role in the prevention of autoimmunity. Here, we present data arguing that the forkhead transcription factor Foxp3 acts as the regulatory T cell lineage specification factor and mediator of the genetic mechanism of dominant tolerance. We show that expression of Foxp3 is highly restricted to the subset αβ of T cells and, irrespective of CD25 expression, correlates with suppressor activity. Induction of Foxp3 expression in nonregulatory T cells does not occur during pathogen-driven immune responses, and Foxp3 deficiency does not impact the functional responses of nonregulatory T cells. Furthermore, T cell-specific ablation of Foxp3 is sufficient to induce the identical early onset lymphoproliferative syndrome observed in Foxp3-deficient mice. Analysis of Foxp3 expression during thymic development suggests that this mechanism is ...
