Scientists have discovered that the absence of a specific protein in cells lining the esophagus may cause inflammation and tissue damage in people with eosinophilic esophagitis (EoE). EoE affects as many as 150,000 people in the United States, many of whom are children. People with EoE experience difficult or painful swallowing, vomiting and nutritional problems because an accumulation of immune cells called eosinophils scars the esophagus.

Infection with Epstein-Barr virus (EBV), the cause of infectious mononucleosis, has been associated with subsequent development of systemic lupus erythematosus and other chronic autoimmune illnesses, but the mechanisms behind this association have been unclear. Now, a novel computational method shows that a viral protein found in EBV-infected human cells may activate genes associated with increased risk for autoimmunity. Scientists supported by the National Institute of Allergy and Infectious Diseases report their findings today in Nature Genetics.
Quality of life for people with type 1 diabetes who had frequent severe hypoglycemia—a potentially fatal low blood glucose (blood sugar) level—improved consistently and dramatically following transplantation of insulin-producing pancreatic islets, according to findings published online March 21 in Diabetes Care.
New clinical trial findings show that a therapeutic regimen involving transplantation of a person’s own blood-forming stem cells can improve survival and quality of life for people with severe scleroderma, a life-threatening autoimmune disease. The regimen, known as myeloablative autologous hematopoietic stem cell transplant (HSCT), includes chemotherapy and total body radiation to destroy the bone marrow followed by transplantation of the person’s own blood-forming stem cells to reconstitute the marrow and immune system.
Combining a 16-week initial course of the medication omalizumab with oral immunotherapy (OIT) greatly improves the efficacy of OIT for children with allergies to multiple foods, new clinical trial findings show. After 36 weeks, more than 80 percent of children who received omalizumab and OIT could safely consume two-gram portions of at least two foods to which they were allergic, compared with only a third of children who received placebo and OIT.
Children exposed to high indoor levels of pet or pest allergens during infancy have a lower risk of developing asthma by 7 years of age, new research supported by the National Institutes of Health reveals. The findings, published September 19 in the Journal of Allergy and Clinical Immunology, may provide clues for the design of strategies to prevent asthma from developing.
Scientists at the National Institutes of Health have expanded the understanding of how chronic inflammation and persistent immune activation associated with HIV infection drive cardiovascular disease risk in people living with HIV. People living with HIV are up to twice as likely to experience heart attacks, strokes and other forms of cardiovascular disease as people who do not have the virus, even when HIV infection is well-controlled with the use of antiretroviral therapy.
May is Asthma Awareness Month, and the National Institutes of Health is finding solutions to improve the health of the nearly 25 million people in the United States who currently have asthma. In recent decades, the prevalence of asthma has been increasing, resulting in millions of urgent medical visits and missed days of work and school each year.
The National Institutes of Health intends to award $42.7 million over seven years to the Consortium of Food Allergy Research (CoFAR) so it may continue evaluating new approaches to treat food allergy. Established in 2005, the CoFAR has been continuously funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH. The first year of funding has been awarded, and awards will be made in subsequent years based on the availability of funds.
The Centers for Disease Control and Prevention (CDC) recommends that children receive pneumococcal conjugate vaccinations (PCV13) against potentially life-threatening pneumococcal disease at two, four and six months of age. Earlier immunization would confer greater protection when infants are most vulnerable to disease, but newborns’ immature immune systems limit their capacity to respond effectively to PCV13 and establish immunity.
A molecule naturally produced by the immune system protects mice and monkeys against Zika virus infection, an international team of researchers has found. Administering the molecule, called 25-hydroxycholesterol or 25HC, to pregnant mice reduced Zika virus infection in the fetal brain and protected against Zika-induced microcephaly. The work was supported in part by the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health.
New clinical trial results provide evidence that high-dose immunosuppressive therapy followed by transplantation of a person's own blood-forming stem cells can induce sustained remission of relapsing-remitting multiple sclerosis (MS), an autoimmune disease in which the immune system attacks the central nervous system.

Administering a human antibody that neutralizes Zika virus to pregnant mice before or after Zika virus infection reduced levels of the virus in placental and fetal tissues and decreased fetal disease, new findings show. The work may aid development of vaccines and therapies for Zika virus infection, which can cause severe birth defects when it occurs during pregnancy.
A wearable patch that delivers small amounts of peanut protein through the skin shows promise for treating children and young adults with peanut allergy, with greater benefits for younger children, according to one-year results from an ongoing clinical trial. The treatment, called epicutaneous immunotherapy or EPIT, was safe and well-tolerated, and nearly all participants used the skin patch daily as directed.
The microbial communities, or microbiota, that naturally colonize the digestive tract in very young infants can affect their risk of later developing childhood allergies and asthma. Scientists now have identified a specific type of microbiota composition and corresponding metabolic environment in the neonatal gut that appears to influence immune cell populations and promote allergy and asthma development. The work was funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
Nearly 80 percent of peanut-allergic preschool children successfully incorporated peanut-containing foods into their diets after receiving peanut oral immunotherapy (OIT), a clinical trial has found. Peanut OIT involves eating small, gradually increasing amounts of peanut protein daily.
Introducing peanut-containing foods during infancy as a peanut allergy prevention strategy does not compromise the duration of breastfeeding or affect children’s growth and nutritional intakes, new findings show. The work, funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is published online on June 10 in the Journal of Allergy and Clinical Immunology.
On World Asthma Day 2016, the National Institutes of Health reaffirms its commitment to support research to improve the lives of all people with asthma. NIH-funded research has advanced our understanding of asthma as a disease as well as the impact asthma has on the lives of those affected.
Medical interventions that work well when tested in mouse models can fail when they advance to safety and efficacy testing in humans. One reason for this, scientists propose, may be the differences between immune system development in laboratory mice and humans.
New clinical trial results show that transplantation of pancreatic islets—cell clusters that contain insulin-producing cells—prevents severe, potentially life-threatening drops in blood sugar in people with type 1 diabetes.
Scientists have identified a protein that may be the cause of tissue damage in patients with eosinophilic esophagitis (EoE), which affects as many as 56 of every 100,000 people in the United States. EoE is a disease in which white blood cells called eosinophils accumulate in the esophagus, often causing difficult or painful swallowing, nausea, vomiting and poor growth in children and adults.
