Shellfish Allergy Immunotherapy: Are We Moving Forward?
View through CrossRef
Shellfish allergy is among the most common food allergies (FAs) worldwide and represents a severe immunoglobulin E (IgE)-mediated FA with tropomyosin functioning as the predominant pan-allergen. Current management of shellfish allergies is strictly palliative with allergen avoidance, underscoring the critical need for disease-modifying therapies. While conventional allergen-specific immunotherapy (AIT) approaches, namely oral and sublingual immunotherapies, demonstrate capacity for desensitization, more clinical applications are needed in the potential safety concerns and prolonged treatment durations. Innovative treatments, such as the design of modified shellfish allergens, DNA vaccine technologies, and nanoparticle-based delivery platforms such as virus-like particles (VLP), show efficacy and potential in inducing protective antibodies while promoting antigen-specific immune tolerance with reduced allergenic risks. These innovative approaches hint at a promising pathway in achieving safe, effective, and long-lasting clinical tolerance for shellfish allergy. This review describes the current perspectives on allergen immunotherapy regarding shellfish allergy and analyzes emerging therapeutic strategies poised to overcome these limitations.
