Allergic rhinitis (AR) with or without conjunctivitis (AR/C) is associated with a significant health and economic burden, and is often accompanied by asthma. Pharmacotherapies are the mainstay treatment options for AR and asthma, but guidelines also recommend allergy immunotherapy (AIT). Unlike pharmacotherapies, AIT has the ability to modify the underlying immunologic mechanisms of AR and asthma with the potential for long-term benefits after treatment is discontinued. Immunotherapy may also prevent progression of AR/C to asthma...

OBJECTIVES: Treatment with allergy immunotherapy improves allergic rhinoconjunctivitis, but can also improve comorbidities associated with allergic rhinitis such as asthma. Sublingual immunotherapy (SLIT)-tablets are a convenient and efficacious method of allergy immunotherapy. They are self-administered after the first tablet has been provided under medical supervision. Therapy may elicit local reactions or, rarely, systemic allergic reactions. The objective of this report is to inform healthcare practitioners about the safety and tolerability profile of SLIT-tablets and use this information to provide practical guidance that may inform patients regarding potential adverse reactions and how to manage them...

Mucosal melanoma of the head and neck is a very rare and aggressive malignancy with a very poor prognosis. The nasal cavity, paranasal sinuses, and oral cavity are the most common locations. One-, 3- and 5-year survival rates between 2000 and 2007 were 63%, 30% and 20%, respectively. Cigarette smoking seems to be a risk factor even though the evidence for this is very low. Clinical signs and symptoms are usually nonspecific. While surgery is considered the mainstay of treatment for most mucosal melanomas of the head and neck region, radiotherapy has a role in local control of the disease after surgery...

PURPOSE OF REVIEW: The current review discusses strategies for administering specific immunotherapy (SIT) for the treatment of food allergy. It focuses on three delivery routes for food allergens, immunomodulatory adjuvants and allergen modifications. RECENT FINDINGS: Interest in SIT for food allergy has been increasing significantly. Sublingual immunotherapy is effective for desensitization with a very favorable adverse event profile. Epicutaneous immunotherapy is also effective, most notably in younger children, with a high rate of local reactions...

The rotavirus-induced diarrhea of human and animal neonates is a major public health concern worldwide. Until recently, no effective therapy is available to specifically inactivate the rotavirion particles within the gut. Passive immunotherapy by oral administration of chicken egg yolk antibody (IgY) has emerged of late as a fresh alternative strategy to control infectious diseases of the alimentary tract and has been applied in the treatment of diarrhea due to rotavirus infection. The purpose of this concise review is to evaluate evidence on the properties and performance of anti-rotavirus immunoglobulin Y (IgY) for prevention and treatment of rotavirus diarrhea in human and animal neonates...

A recombinant antigen targeting α-synuclein was produced in the plant cell rendering an immunogenic protein capable to induce humoral responses in mice upon oral administration. Synucleinopathies are neurodegenerative diseases characterized by the abnormal accumulation of α-synuclein (α-Syn, a 140 amino acid protein that normally plays various neurophysiologic roles) aggregates. Parkinson's disease (PD) is the synucleinopathy with the highest epidemiologic impact and although its etiology remains unknown, α-Syn aggregation during disease progression pointed out α-Syn as target in the development of immunotherapies...

Several types of vaccine-delivering tumor-associated antigens (TAAs) have been developed in basic and clinical research. Wilms' tumor 1 (WT1), identified as a gene responsible for pediatric renal neoplasm, is one of the most promising TAA for cancer immunotherapy. Peptide and dendritic cell-based WT1 cancer vaccines showed some therapeutic efficacy in clinical and pre-clinical studies but as yet no oral WT1 vaccine can be administrated in a simple and easy way. In the present study, we constructed a novel oral cancer vaccine using a recombinant Bifidobacterium longum displaying WT1 protein...

PURPOSE: Interleukin (IL)-9 induces allergic responses; however, the roles of anti-IL-9 antibody in the induction of tolerance remain unclear. This study investigated the effects of anti-IL-9 antibody on oral tolerance (OT) in a mouse model of allergic rhinitis (AR). METHODS: BALB/c mice were divided into 4 groups: the control, AR, OT, and OT with anti-IL-9 antibody (OT+IL9AB) groups. Ovalbumin (OVA) was used for sensitization and challenge. Mice in the OT and OT+IL9AB groups were fed OVA for immunotherapy...

Five years have passed since the Japanese Pediatric Guideline for Food Allergy (JPGFA) was first revised in 2011 from its original version. As many scientific papers related to food allergy have been published during the last 5 years, the second major revision of the JPGFA was carried out in 2016. In this guideline, food allergies are generally classified into four clinical types: (1) neonatal and infantile gastrointestinal allergy, (2) infantile atopic dermatitis associated with food allergy, (3) immediate-type of food allergy (urticaria, anaphylaxis, etc...

BACKGROUND: There are no established therapies specific for NRAS-mutant melanoma despite the emergence of immunotherapy. We aimed to assess the efficacy and safety of the MEK inhibitor binimetinib versus that of dacarbazine in patients with advanced NRAS-mutant melanoma. METHODS: NEMO is an ongoing, randomised, open-label phase 3 study done at 118 hospitals in 26 countries. Patients with advanced, unresectable, American Joint Committee on Cancer stage IIIC or stage IV NRAS-mutant melanoma who were previously untreated or had progressed on or after previous immunotherapy were randomised (2:1) to receive either binimetinib 45 mg orally twice daily or dacarbazine 1000 mg/m(2) intravenously every 3 weeks...

Current clinical research focuses on food allergen-specific immunotherapy through oral (OIT), sublingual (SLIT), or epicutaneous (EPIT) routes. Immunotherapy relies on the delivery of gradually increasing doses of specific allergens to induce desensitization (defined as temporary antigen hyporesponsiveness that depends on regular food ingestion) and, ultimately, tolerance (defined as the ability to ingest food without symptoms despite prolonged periods of avoidance or irregular intake). Although the majority of the patients treated with OIT achieve desensitization, only a minority achieves tolerance...

This is the first prospective study of a combination therapy involving a cardenolide and a MEK inhibitor for metastatic melanoma. Whereas BRAF mutant melanomas can exhibit profound responses to treatment with BRAF and MEK inhibitors, there are fewer options for BRAF wild-type melanomas. In preclinical studies, we discovered that cardenolides synergize with MEK inhibitor to promote the regression of patient-derived xenografts irrespective of BRAF mutation status. We therefore conducted a phase 1B study of digoxin 0...

Maitake α-glucan, YM-2A, isolated from Grifola frondosa, has been characterized as a highly α-1,6-branched α-1,4 glucan. YM-2A has been shown to possess an anti-virus effect in mice; however, it does not directly inhibit growth of the virus in vitro, indicating that the anti-virus effect of YM-2A might be associated with modulation of the host immune system. In this study, we found that oral administration of YM-2A could inhibit tumor growth and improve survival rate in two distinct mouse models of colon-26 carcinoma and B16 melanoma...

BACKGROUND: Anaphylaxis is a life-threatening condition for which we have limited therapeutic options. Although specific immunotherapy for food allergies is becoming more effective, it is still laborious and carries substantial risk of adverse events. On the other hand, regulatory dendritic cell (DC) therapy is effective in mouse models of allergic disease and has been shown to work with TH2 cells from atopic asthmatic patients. OBJECTIVE: We assessed whether DC immunotherapy could reverse food allergen sensitivity in mouse models to provide proof of concept relating to their use in the clinic...

The loss of the Von Hippel-Lindau tumor suppressor (VHL) is a key oncogenic event in the vast majority of patients with clear cell renal cell carcinoma (ccRCC). With the loss of the VHL protein (pVHL) function, the hypoxia inducible factor α (HIF-α) accumulates inside the tumor cell and dimerizes with HIF-β. The HIF-α/HIF-β complex transcriptionally activates hundreds of genes promoting the adaptation to hypoxia that is implicated in tumor development. There is growing evidence showing that HIF-2α subunit has a central role in ccRCC over HIF-1α...

Allergen-specific immunotherapy (AIT) is currently recognized as a clinically effective treatment for allergic diseases, with a unique disease-modifying effect. AIT was introduced in clinical practice one century ago, and performed in the early years with allergenic extracts of poor quality and definition. After the mechanism of allergic reaction were recognized, the practice of AIT was refined, leading to remarkable improvement in the efficacy and safety profile of the treatment. Currently AIT is accepted and routinely prescribed worldwide for respiratory allergies and hymenoptera venom allergy...

BACKGROUND: Clinical desensitization and oral food immunotherapy are therapeutic interventions that allow individuals who react adversely to an allergen (drug or food) to be made tolerant to the allergen. However, tolerance is brief and allergen hypersensitivity can recur within days following allergen withdrawal. OBJECTIVE: We hypothesize that the reason these treatments are temporary reflects rapid recovery of mast cells from a desensitized state. We sought to test this...

Food allergy is a common health problem worldwide, with increasing prevalence during recent decades. The only approved treatments for food allergy are food avoidance and administration of emergency medications in case of accidental exposure, which negatively affects patients' quality of life, so new treatments are highly desirable. Different food immunotherapy modalities have recently been used, with variable success rates in the induction of desensitization and tolerance, and different numbers and types of adverse reactions...

Autoantigen-specific immunological tolerance represents a central objective for prevention of type 1 diabetes (T1D). Previous studies demonstrated mucosal antigen administration results in expansion of Foxp3(+) and LAP(+) regulatory T cells (Tregs), suggesting oral delivery of self-antigens might represent an effective means for modulating autoimmune disease. Early preclinical experiments using the non-obese diabetic (NOD) mouse model reported mucosal administration of T1D-related autoantigens [proinsulin or glutamic acid decarboxylase 65 (GAD)] delayed T1D onset, but published data are conflicting regarding dose, treatment duration, requirement for combinatorial agents, and extent of efficacy...
