Narcolepsy is a rare neurologic disorder characterized by excessive daytime sleepiness, cataplexy and disturbed nocturnal sleep patterns. Narcolepsy type 1 (NT1) has been shown to result from a selective loss of hypothalamic hypocretin-secreting neurons with patients typically showing low CSF-hypocretin levels (<110 pg/ml). This specific loss of hypocretin and the strong association with the HLA-DQB1*06:02 allele led to the hypothesis that NT1 could be an immune-mediated pathology. Moreover, susceptibility to NT1 has recently been associated with several pathogens, particularly with influenza A H1N1 virus either through infection or vaccination...

Cytokines are implicated in the immunopathogenesis of multiple sclerosis (MS). Interleukin (IL)-33, one of the recently discovered members of the IL-1 superfamily, is a dual functional cytokine involved in various autoimmune disorders. In a case-control study, venous blood was collected from healthy subjects categorized as control group (n=44) and MS patients (n=44). All recruited patients were clinically diagnosed with relapsing-remitting MS (RRMS), including patients without treatment (new identified cases, n=16) and those treated with interferon beta (IFN-β) (n=28)...

Helminths cause chronic infections and affect the immune response to unrelated inflammatory diseases. Although helminths have been used therapeutically to ameliorate inflammatory conditions, their anti-inflammatory properties are poorly understood. Alternatively activated macrophages (AAMϕs) have been suggested as the anti-inflammatory effector cells during helminth infections. Here, we define the origin of AAMϕs during infection with Taenia crassiceps, and their disease-modulating activity on the Experimental Autoimmune Encephalomyelitis (EAE)...

Intravenous immunoglobulin (IVIG) is pooled immunoglobulin G derived from human blood donors. It was introduced in the early 1980s to treat immunodeficiency disorders. Since then, its use has expanded to other fields such as neurology, rheumatology, and hematology. IVIG has been used to provide passive immunity in qualitative and quantitative immunoglobulin disorders, to neutralize antibodies in immune-mediated diseases, and as an immune modulatory agent. The difficulty of producing IVIG in high quantities, in addition to a growing list of "off-label" indications, has resulted in a worldwide shortage and increase in cost...

Since the mid 1970s, when membrane modules became available, plasma separation techniques have gained in importance especially in the past few years. The advantages of this method are a complete separation of the corpuscular components from the plasma and due to increased blood flow rate and higher efficacy. Systemic autoimmune diseases based on an immune pathogenesis produce autoantibodies and circulating immune complexes, which cause inflammation in the tissues of various organs. In most cases, these diseases have a poor prognosis without treatment...

OBJECTIVE: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by extensive immune response including over-activation of T and B cells development of pathogenic autoantibodies, organ damage induced by the formation and deposition of immune complex, and the abnormal elevation of type I interferon. Semaphorin5A (Sema5A), is essentially involved in immune cell regulation and also implicated in the pathogenesis of autoimmune disorders. We aimed to evaluate the role of Sema5A in patients with SLE...

Neuromyelitis optica (NMO) is an autoimmune disorder of the central nervous system (CNS) mediated by antibodies to water channel protein AQP4 expressed in astrocytes. The contribution of AQP4-specific T cells to the class switch recombination of pathogenic AQP4-specific antibodies and to the inflammation of the blood-brain-barrier is incompletely understood, as immunogenic naturally processed T-cell epitopes of AQP4 are unknown. By immunizing Aqp4(-/-) mice with full length murine AQP4 protein followed by recall with overlapping peptides, we here identify AQP4(201-220) as the major immunogenic IA(b) -restricted epitope of AQP4...

An 84-year-old woman was referred to our hospital presenting anemia. Her hemoglobin level was 5.8 g/dL, and white blood cell count was 9400/μL, consisting of 82% lymphocytes. Given the lymphocyte phenotype (CD2+, CD3-, CD16+, and CD56-) and negative whole blood EBV viral load, we made a diagnosis of chronic lymphoproliferative disorder of NK cells (CLPD-NK). We suspected hemolytic anemia because of the high levels of reticulocytes in the peripheral blood and the low haptoglobin value. Although the direct Coombs test was negative and there was no cold agglutination, we examined her red-blood-cell-bound IgG (RBC-IgG), which was elevated...

Multiple sclerosis (MS) is a neurological autoimmune disorder of the central nervous system (CNS), characterized by recurrent episodes of inflammatory demyelination and consequent axonal deterioration. The hallmark of the disease is the demyelinated plaque, a hypocellular area characterized by formation of astrocytic scars and infiltration of mononuclear cells. Recent studies have revealed that both innate and adaptive immune cells contribute to the pathogenesis of MS and its experimental autoimmune encephalomyelitis (EAE) model...

BACKGROUND: Renal complications of non-Hodgkin lymphoma encompass a wide spectrum of monoclonal Ig-related pathologies. Clonal circulating T cells can also be associated with non-renal autoimmune disorders induced by overproduction of specific patterns of cytokines or unbalanced lymphocytes sub-populations. METHODS: Immunophenotyping of circulating T cells and TCR gene restriction analysis using Biomed-2 protocol. NF-κB staining and mRNA quantification of inflammatory genes in HK-2 epithelial renal cells exposed to supernatants of peripheral blood mononuclear cells with clonal T-cell population...

OBJECTIVE: Autoimmune thyroid disease (AITD) is an organ-specific disorder due to the interplay between environmental and genetic factors. Toll-like receptors (TLRs) are pattern recognition receptors expressed abundantly on monocytes. There is a paucity of data on TLR expression in AITD. The aim of this study was to examine TLR expression, activation, ligands, and downstream signaling adaptors in peripheral blood mononuclear cells (PBMCs) extracted from untreated AITD patients and healthy controls...

Loss of CD28 expression by CD8+ T cells occurs with age and during chronic inflammatory conditions. CD8+CD28- T cells are a heterogeneous cell subpopulation whose function ranges from immunosuppressive to effector. Here we analyzed the role of CD8+CD28- T cells in the pathogenesis of systemic sclerosis (SSc), a connective tissue disorder characterized by autoimmunity, vasculopathy and extensive cutaneous and visceral fibrosis. We show that the frequency of CD8+CD28- T cells is increased in the blood and affected skin of SSc patients, independent of patient age, and correlates with the extent of skin fibrosis...

Rheumatoid arthritis (RA) is a long-lasting intractable autoimmune disorder, which has become a substantial public health problem. Despite widespread use of biologic drugs, there have been uncertainties in efficacy and long-term safety. Mesenchymal stem cells (MSCs) have been suggested as a promising alternative for the treatment of RA because of their immunomodulatory properties. However, the precise mechanisms of MSCs on RA-related immune cells are not fully elucidated. The aim of this study was to investigate the therapeutic potential of human umbilical cord blood-derived MSCs (hUCB-MSCs) as a new therapeutic strategy for patients with RA and to explore the mechanisms underlying hUCB-MSC-mediated immunomodulation...

Sheehan syndrome or postpartum hypopituitarism is a condition characterized by hypopituitarism due to necrosis of the pituitary gland. The initial insult is caused by massive postpartum haemorrhage (PPH), leading to impaired blood supply to the pituitary gland, which has become enlarged during pregnancy. Small sella turcica size, vasospasms (caused by PPH) and/or thrombosis (associated with pregnancy or coagulation disorders) are predisposing factors; autoimmunity might be involved in the progressive worsening of pituitary functions...
