Antigen presentation determines immunologic outcome, and by modifying the presentation of allergen to the host one can prevent an allergic response. Under certain conditions, covalent linkage, of ovalbumin to rat IgG, a molecule already tolerated by the host, can make a protein-IgG conjugate which down-regulates the immune response to this food allergen. The suppression is allergen specific. It affects both T and B cell immune responses. Administration of allergens linked to isologous IgG may provide a novel strategy for allergy prevention.

Non-specific Lipid Transfer proteins (nsLTPs) are relevant allergens of several pollens and plant foods. Sensitization to nsLTPs is not typical in our region. Still, it has become an increasingly common cause of IgE-mediated food allergies and food-induced anaphylaxis in Northern Europe in recent decades.

Purpose Of Review: Regulatory B cells (Bregs) are a key component in the regulation of the immune system. Their immunosuppressive function, which includes limiting the inflammatory cascade, occurs through interactions with other immune cells and the secretion of cytokines, primarily IL-10. As knowledge about B cells continues to expand, their diversity is becoming more recognized, with many subpopulations identified in both human and animal models.

Objectives: Traditional methods of treating allergies primarily revolve around avoiding allergens and promptly using rescue medications when allergic symptoms occur. However, this approach is known for its inefficiency and limited success in achieving long-term relief. Our aim was to conduct a comprehensive analysis of previously published randomized controlled trials (RCTs) that explore the effectiveness and safety of epicutaneous immunotherapy (EPIT) as a means to manage food allergies in children.

Background: Peanut allergy (PA) is one of the most prevalent food allergies with a lack of favorable safety/efficacy treatment. A cucumber mosaic virus-like particle expressing peanut allergen component Ara h 2 (VLP Peanut) has been developed as a novel therapeutic approach for PA.
Objective: We assessed the tolerogenic properties and reactivity of VLP Peanut.
