Neurons reprogramme encephalitogenic T cells (Tenc) to regulatory T cells (Tregs), either FoxP3(+)Tregs or FoxA1(+)Tregs. We reported previously that neuronal ability to generate FoxA1(+)Tregs was central to preventing neuroinflammation in experimental autoimmune encephalomyelitis (EAE). Mice lacking interferon (IFN)-β were defective in generating FoxA1(+)Tregs in the brain. Here we show that lack of neuronal IFNβ signalling is associated with the absence of programme death ligand-1 (PDL1), which prevents their ability to reprogramme Tenc cells to FoxA1(+)Tregs...

Episodic angio-oedema with eosinophilia (EAE) or Gleich's syndrome is a rare condition characterised by recurrent episodes of oedema and eosinophilia, accompanied by urticaria, fever and weight gain. The presence of ascites has not been reported so far. We report a 21-year-old Caucasian woman who presented with marked ocular oedema and ascites. Laboratory evaluation revealed marked eosinophilia. During the last 3 months, three episodes of facial and neck oedema were reported, which resolved spontaneously over a period of 3-5 days...

Multiple sclerosis (MS) is a chronic, incurable, inflammatory disease of the central nervous system (CNS). In the United States, several US Food and Drug Administration (FDA)-approved disease-modifying treatments (DMTs) are available, including glatiramer acetate (GA; Copaxone®), one of the most longstanding treatments. GA was discovered serendipitously in the late 1960s/early 1970s while attempting to produce a synthetic antigen capable of inducing experimental autoimmune encephalomyelitis (EAE), an animal model of autoimmune inflammatory CNS disorders, including MS...

Recombinant human myelin basic protein (rhMBP) was previously produced in the milk of transgenic cows. Differences in molecular recognition of either hMBP or rhMBP by surface-immobilized anti-hMBP antibodies were demonstrated. This indicated differences in immunological response between rhMBP and hMBP. Here, the activity of free and controlled release rhMBP poly(ε-caprolactone) nanoparticles (NPs), as a therapeutic vaccine against multiple sclerosis (MS) was demonstrated in experimental autoimmune encephalomyelitis (EAE) animal model...

BACKGROUND: Bladder dysfunction is an important symptom of experimental autoimmune encephalomyelitis (EAE). Our previous study showed that EAE-induced upregulation of the E-prostanoid receptor 3 (EP3) and E-prostanoid receptor 4 (EP4) in the bladder was accompanied by bladder dysfunction. Although many other studies have evaluated the lower urinary tract symptoms in multiple sclerosis, the mechanism remains unclear. OBJECTIVES: To investigate the effects of interstitial cells of Cajal (ICC) on bladder dysfunction in a novel neurogenic bladder model induced by experimental autoimmune encephalomyelitis...

Neurologic disease diagnosis and treatment is challenging. Multiple Sclerosis (MS) is a demyelinating autoimmune disease with few clinical forms and uncertain etiology. Current studies suggest that it is likely caused by infection(s) triggering a systemic immune response resulting in antigen/non-antigen-related autoimmune response in central nervous system (CNS). New therapeutic approaches are needed. Secreted by viable embryos, PreImplantation Factor (PIF) possesses a local and systemic immunity regulatory role...

Shiga toxin (Stx)-producing Escherichia coli (STECs) cause non-bloody diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome, and are the primary cause of acute renal failure in children worldwide. This study investigated the correlation of genetic makeup of STEC strains as revealed by DNA microarray to clinical symptoms and the duration of STEC shedding. All STEC isolated (n = 96) from patients <10 years of age in Jönköping County, Sweden from 2003 to 2015 were included. Isolates were characterized by DNA microarray, including almost 280 genes...

Metabolism of the essential amino acid tryptophan (trp) is a key endogenous immunosuppressive pathway restricting inflammatory responses. Tryptophan metabolites promote regulatory T cell (Treg) differentiation and suppress proinflammatory T helper cell (Th)1 and Th17 phenotypes. It has been shown that treatment with natural and synthetic tryptophan metabolites can suppress autoimmune neuroinflammation in preclinical animal models. Here, we tested if oral intake of tryptophan would increase immunosuppressive tryptophan metabolites and ameliorate autoimmune neuroinflammation as a safe approach to treat autoimmune disorders like multiple sclerosis (MS)...

The concept as to how the brain maintains its immune privilege has initially been based on observations that it is lacking classical lymph vessels and later, the absence of dendritic cells (DC). This view has been challenged by several groups demonstrating drainage/migration of injected tracers and cells into cervical lymph nodes (CLNs) and the presence of brain antigens in CLNs in the course of various brain pathologies. Using CD11c-diphtheria toxin receptor (DTR)-green fluorescent protein (GFP) transgenic (tg) mice, we have shown the existence of CD11c(+) cells, a main DC marker, within the brain parenchyma...

Glycogen synthase kinase (GSK)-3β has been known as a pro-inflammatory molecule in neuroinflammation. The involvement of GSK-3β remains unsolved in acute monophasic rat experimental autoimmune encephalomyelitis (EAE). The aim of this study was to evaluate a potential role of GSK-3β in central nervous system (CNS) autoimmunity through its inhibition by lithium. Lithium treatment significantly delayed the onset of EAE paralysis and ameliorated its severity. Lithium treatment reduced the serum level of pro-inflammatory tumor necrosis factor a but not that of interleukin 10...

Cattle are a major reservoir of the six major Shiga toxin-producing non-O157 Escherichia coli (STEC) serogroups (O26, O45, O103, O111, O121, and O145) responsible for foodborne illnesses in humans. Besides prevalence in feces, the concentrations of STEC in cattle feces play a major role in their transmission dynamics. A subset of cattle, referred to as super shedders, shed E. coli O157 at high concentrations (≥4 log CFU/g of feces). It is not known whether a similar pattern of fecal shedding exists for non-O157...

To get insights in the temporal pattern of commensal Escherichia coli populations, we daily sampled feces of four healthy cows from the same herd over 25 days, in the Hwange district of Zimbabwe. The cows did not receive antibiotic treatment during the 3 previous months. We performed viable E. coli counts, and characterized at a clonal level, screened for stx and eae genes, and tested for antibiotic susceptibilities the 326 isolates originating from the 98 sampled stools. We observed that E. coli counts and dominant clones were different among cows, and very few clones were shared...

Experimental autoimmune encephalomyelitis (EAE) has been used as an animal model of multiple sclerosis to identify pathogenic cytokines that could be therapeutic targets. Granulocyte-macrophage colony-stimulating factor (GM-CSF) is the only cytokine reported to be essential for EAE. We investigated the role of GM-CSF in EAE in C3HeB/FeJ mice that uniquely exhibit extensive brain and spinal cord inflammation. Unexpectedly, GM-CSF-deficient C3HeB/FeJ mice were fully susceptible to EAE because IL-17 activity compensated for the loss of GM-CSF during induction of spinal cord-targeted disease...

Shiga toxin-producing Escherichia coli (STEC) O157:H7 and serogroups O26, O45, O103, O111, O121, and O145 are often referred to as the "top seven" STEC, and these have been declared to be adulterants in beef by the U.S. Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS). The aim of this work was to compare the methods described in the USDA FSIS Microbiology Laboratory Guidebook (MLG) to a two-stage Applied Biosystems RapidFinder STEC real-time PCR method to test for the top seven STEC in raw ground beef...

Specific miRNAs are involved in the pathogenesis of multiple sclerosis (MS), during which IL-17-producing CD4(+) T helper (Th17) cells accumulate in the central nervous system (CNS). In this study, we identified levels of miR-384 as significantly increased in mice with experimental autoimmune encephalomyelitis (EAE), an animal model of MS. Over-expression of miR-384 in vivo led to severe EAE, characterized by exacerbated demyelination, and increased inflammatory cell infiltration of the spinal cord; inhibition of miR-384 reversed these changes...

T helper type 17 cells (Th17 cells) are major contributors to many autoimmune diseases. In this study, we demonstrate that the germinal center kinase family member MINK1 (misshapen/NIK-related kinase 1) negatively regulates Th17 cell differentiation. The suppressive effect of MINK1 on induction of Th17 cells is mediated by the inhibition of SMAD2 activation through direct phosphorylation of SMAD2 at the T324 residue. The importance of MINK1 to Th17 cell differentiation was strengthened in the animal model of experimental autoimmune encephalomyelitis (EAE)...

Cattle manure is one of the primary larval developmental habitats of house flies, Musca domestica (L.). Cattle serve as asymptomatic reservoirs of Shiga toxin-producing Escherichia coli (STEC), and bacteria are released into the environment in cattle feces. The USDA-FSIS declared seven STEC serogroups (O157, O26, O45, O103, O145, O121, and O111) as adulterants in beef products. In addition, the serogroup O104 was a culprit of a large outbreak in Germany in 2011. Our study aimed to assess the prevalence of seven non-O157 STEC (O26, O45, O145, O103, O121, O111, and O104) serogroups in adult house flies...
