This study investigates how the immune system of children with celiac disease responds to controlled, small amounts of gluten. Children on a strict gluten-free diet are randomly assigned to receive either placebo, 50 mg of gluten, or 5 g of gluten once daily for three days, simulating real-life accidental exposure or dietary transgression. Blood samples are collected on Day 1 (before gluten intake) and Day 8 (five days after the last dose). Stool and urine samples are also collected for complementary analyses. Using single-cell ribonucleic acid (RNA) sequencing, T-cell receptor sequencing, microRNA profiling, and exploratory metabolomics, the study aims to characterize changes in immune cell populations and gene expression after gluten exposure. The objective is to determine whether even very small amounts of gluten induce measurable systemic immune responses and whether these responses differ according to the dose administered. Understanding these mechanisms may support the development of new biomarkers and improve clinical management of pediatric celiac disease.

NCT01420133
Few recommendations concerning the diet and dosage to be administered to patients treated with corticosteroids are established. It therefore seems important to study prospectively the indication of a diet low in salt and sugar in patients undergoing corticosteroid therapy, to record side effects observed and to measure their frequency.
NCT06948110
Background: Autoimmune diseases can be caused by genes people inherit from their parents. The gene changes that cause these diseases have been well studied in people with European and Asian ancestors. But some diseases behave differently in people who are native to North and South America. Researchers want to know more about the gene changes and other factors that may cause autoimmune diseases among these people. This project will be based in Peru. Objective: To study how gene changes can lead to autoimmune diseases in people native to Peru. Eligibility: People aged 18 years and older with an autoimmune disease. These may include systemic lupus erythematosus; Sjogren disease; scleroderma; rheumatoid arthritis; seronegative spondylo-arthropathies; and systemic vasculitis. Family members and healthy volunteers are also needed. Design: Participants will have 2 clinic visits; these will be 2 weeks apart. The clinics will be in Lima, Iquitos, and other sites in Peru. Visit 1: Participants will have a physical exam. They will answer questions about their health risks and habits. They will provide blood and urine samples. Visit 2: Participants will provide a second blood sample and a stool sample. They will talk about the results of their first clinical exam with researchers. The cost of travel to and from the clinics will be provided. Participants will get $30 per visit and a snack.

Type I interferonopathies are rare autoinflammatory disorders caused by genetic defects and associated with significant morbidity and mortality. These diseases are refractory to conventional immunosuppressive therapies. They typically occur in childhood, although disease onset in adulthood has been observed. The clinical spectrum is wide and mainly involves the central nervous system. Joint involvement is also common, and more rarely, haematological features such as cytopenias or immunodeficiency may be observed. Nearly all patients show consistent over-activation of the type I IFN pathway, as evidenced, the expression of IFN-stimulated genes, the so-called 'interferon signature'. To date, the natural history of interferonopathies remains unclear. In this context, the establishment of a natural history of type I interferonopathy in patients is proposed to elucidate the pathophysiological mechanisms and identify biomarkers for diagnosis, prognosis, and disease activity, with the aim of better characterising the diversity of interferonopathies. The main objective is to characterise the evolution of the pathology in paediatric and adult patients with type I interferonopathies. The overall aim of this research is to propose therapeutic options tailored to patient phenotypes and to better define patient sub-groups in order to optimise the preparation of future clinical trials.

NCT05544448
Interleukin 2 (IL-2) is a critical cytokine for the survival and function of regulatory T cells (LTreg). This cytokine has a dual role in the immune system. IL-2 stimulates immune responses by acting on the intermediate affinity IL-2R receptor, IL-2Rβγ, expressed by conventional T cells (LTconv) during activation, but also contributes to the inhibition of immune responses via LTreg that express the high affinity receptor IL-2Rαβγ. This difference in IL-2 receptor affinity for IL-2 has led to the development of low-dose IL-2 therapy to stimulate LTreg and improve control of excessive inflammation in autoimmune (AID), inflammatory or alloimmune diseases Low-dose IL-2 therapy is being studied in several of these diseases such as systemic lupus erythematosus, type 1 diabetes, alopecia, HCV (hepatitis C virus)-induced vasculitis, atopic dermatitis and chronic allo-transplantation-related graft-versus-host disease (GVHD). Some of these studies have shown an increase in LTreg numbers and an improvement in certain clinical signs. To improve LTreg targeting in autoimmune diseases, inflammatory diseases or GVHD, mutated IL-2s (muteins) have been developed with selective LTreg agonist properties. These IL-2 muteins are linked to an Fc fragment to increase their half-life. Two IL-2 variants (IL-2Vs)-Fc preferentially stimulate STAT5 phosphorylation in LTregs compared to conventional FoxP3- (LTconv) CD4+ or CD8+ T cells

NCT07388212
Autoimmune diseases are a type of chronic disabling disease, characterized by the immune system incorrectly recognizing and attacking the body's own tissues, leading to tissue damage and organ dysfunction, seriously threatening life and health. Although there are various treatment methods currently available, there are still many limitations to immune related diseases that aim for long-term remission, and further research and breakthroughs are urgently needed. Targeting and clearing B cells is one of the core strategies in the treatment of autoimmune diseases. Its mechanism mainly involves clearing abnormally activated B cells, reducing the production of autoantibodies, and regulating immune disorders. The therapy targeting CD19 has become an important research and development direction due to its ability to clear a wider range of B cell lineages (including plasma cells), which may achieve deeper levels of B cell depletion than CD20 targeted therapy. In addition, BCMA is highly expressed specifically on plasma cells, especially long-lived plasma cells, and is a key target for clearing the source of antibody production. Therefore, the CD19/BCMA dual target therapy aims to achieve more complete coverage of the antibody production pathway by simultaneously targeting B cells (and precursors) and plasma cells, which is expected to further improve the treatment response rate and achieve deeper and more persistent immune reset. The advent of COVID-19 vaccine has brought LNP mRNA technology into the public's view. After years of development, it not only shines brilliantly in COVID-19 vaccine, but also is widely used in the treatment and exploration of cancer, rare diseases and other fields. The core of LNP mRNA technology targeting CD19/BCMA is to encapsulate the mRNA encoding specific proteins (such as anti-CD19/BCMA related proteins) in lipid nanoparticles and deliver them to the body through intravenous or intramuscular injection. This experimental drug is a messenger ribonucleic acid (mRNA) therapeutic drug based on the dual targets of CD19 and BCMA, formed by loading mRNA encoding CD19/BCMA receptor related proteins onto lipid nanoparticles (LNP) for injection.

NCT07362758
Autoimmune diseases, such as immune thrombocytopenia (ITP), immune hemolytic anemia (AIHA), systemic lupus erythematosus (SLE), lupus nephritis (LN), idiopathic inflammatory myopathy (IIM), ulcerative colitis (UC), and systemic sclerosis (SSc), are a type of chronic disabling disease characterized by the immune system mistakenly attacking the body itself, leading to tissue damage and organ dysfunction.Autoimmune hematological diseases, especially difficult to treat autoimmune diseases, are a type of disease that is difficult to treat and has a significant impact on patients' lives. Although there are various treatment methods currently available, there are still many limitations to autoimmune sexually transmitted diseases that aim for long-term remission, and further research and breakthroughs are urgently needed. The advent of COVID-19 vaccine has brought LNP mRNA technology into the public's view. After years of development, it not only shines brilliantly in COVID-19 vaccine, but also is widely used in the treatment and exploration of cancer, rare diseases and other fields. Lipid nanoparticles (LNP) are currently the most mature non viral delivery platform, capable of protecting mRNA from nuclease degradation, promoting intracellular uptake, and achieving efficient translation in vivo. The core of LNP-mRNA technology targeting CD19 is to encapsulate the mRNA encoding specific proteins (such as anti-CD19 related proteins) in lipid nanoparticles and deliver them to the body through intravenous or intramuscular injection.
