..Using a mouse model in which the sensitizing nuts are controlled may provide novel methods to investigate in vivo and T cell cross-reactivity...

..There is no current active treatment for food allergy. Traditional injection immunotherapy has been proved unsafe, and thus there is a need for other forms of immunotherapy...

..Hen's egg allergy is among the most common food allergies in childhood and predicts later development of allergic disease. The optimal efficacy and mechanism(s) of egg allergen immunotherapy are poorly understood...

..For egg allergy, dietary avoidance is the only currently approved treatment. We evaluated oral immunotherapy using egg-white powder for the treatment of children with egg allergy...

..Oral immunotherapy (OIT) offers a promising therapeutic option for peanut allergy. Given that during OIT an allergic patient ingests an allergen that could potentially cause a serious reaction, the safety of OIT is of particular concern...

..On the basis of these findings, we now recommend that patients eat peanut frequently and carry epinephrine indefinitely until they have demonstrated ongoing peanut tolerance...

..CONCLUSIONS: Soy IT can be used to desensitize/downregulate peanut-specific response in peanut-allergic mice and could provide a new therapeutic intervention for peanut allergy...

..Development of these immunotherapy strategies has generated much excitement in the food allergy community; however, further studies are needed before these approaches are ready for clinical use...

..Further study to clarify the role of tolerance in the development of eosinophilic gastrointestinal diseases can help identify potential prevention strategies and therapeutic targets...

..Open-label oral immunotherapy (OIT) protocols have been used to treat small numbers of patients with peanut allergy. Peanut OIT has not been evaluated in double-blind, placebo-controlled trials...

..The focus of this review will be on recent animal models of food allergy. Animal models are being used to investigate underlying mechanisms of IgE-mediated disease and for prophylactic/intervention therapies to treat allergic disease...

..Both PNAg and purified Ara h 1 induced Erk 1/2 phosphorylation of MDDCs, consistent with previous reports on the effect of Th2 adjuvants on DCs...

..IgE-mediated allergic reactions to cashews and other nuts can trigger life-threatening anaphylaxis. Proactive therapies to decrease reaction severity do not exist...

..Food allergy is among the clinical disorders that occur from a failure of this system, and therapies that seek to re-establish tolerance are currently under investigation...

..These results show that immunotherapy with modified PN proteins and HKLM is effective for treating PN allergy in this model, and may be a potential approach for treating PNA...

..There are no treatments currently available for peanut allergy. Sublingual immunotherapy (SLIT) is a novel approach to the treatment of peanut allergy...

..Immunotherapy has been studied as a treatment for pollen food syndrome, with highly variable results...

..This qualitative difference in epitope diversity might provide prognostic information about the patient...

..An author group was formed to describe the natural history, prevalence, diagnosis, and treatment of food allergies in the context of the global community...

..Adjacent IgE molecules bound to the surface of the mast cell become cross-linked, causing mast cell degranulation and release of powerful vasoactive compounds that cause allergic symptoms...

..Here we discuss the relationship of food allergy to oral tolerance and review recent oral tolerance studies, focusing on the mechanistic role of antigen presenting cells and the generation of regulatory T cells in mice and humans...

..Orally administered, food-specific immunotherapy appears effective in desensitizing and potentially permanently tolerizing allergic individuals...

....

..CONCLUSIONS: Patients with a history of peanut allergy and peanut-IgE levels of 5 or less have at least a 50% chance of outgrowing their allergy. Recurrence of peanut allergy may occur but appears to be uncommon...

..Various immunotherapy approaches are under investigation to alleviate or prevent food-induced reactions in those who have persistent food allergies...

..This article examines the mechanisms of oral tolerance and the breakdown that leads to food allergy, as well as the history and current state of oral and sublingual immunotherapy development...

..CONCLUSIONS: Improved understanding of the molecular structure of the major peanut allergens and the peanut-specific immune response has lead to significant diagnostic and therapeutic advances in the study of peanut allergy...

..Food allergy is a difficult clinical problem for which no disease-modifying therapy currently exists...

..This article examines adverse food reactions that are IgE-mediated, non-IgE-mediated, and those entities that have characteristics of both...

..The use of the anti-IgE therapy in conjunction with other immunotherapy would possibly be the best treatment option in the future...

..This review will focus on the concepts of a holistic approach to food allergy that is working to improve CARE for subjects with food allergy, including new advances in clinical care, advocacy, research, and education...

..The array of treatment modalities currently being investigated increases the likelihood of finding one or more effective therapies for the treatment of food allergy...

....

..Because inadvertent ingestion of peanut often leads to life threatening reactions and peanut allergy is often long-lived, many investigators are focusing on decreasing clinical reactivity after peanut allergy is established...

....

..The model will be useful for determining IgE-mediated mechanisms and conducting endoscopic histologic assessment of tissues and immunotherapeutic intervention strategies with repeated allergen challenges...

....

..It is the combination of these different approaches that would probably offer the best treatment option for food-allergic patients in a not too distant future...

..Allergen nonspecific methods act via a more global TH2 suppressive mechanism and may be useful for those patients with multiple food allergies...

..The goal of this investigation was to determine the effect of pesticide exposure on respiratory symptoms and lung function in workers with occupational exposure to pesticides...

....

..CONCLUSIONS: Treatment with pr HKE-MP123 can induce long-term "downregulation" of peanut hypersensitivity, which might be secondary to decreased antigen-specific T(H)2 and increased T(H)1 and T regulatory cytokine production...
