Mice that received treatments with peanut-coated microneedles had significant increased rates of desensitization to peanut allergy compared with epicutaneous immunotherapy (EPIT), a new study found. The microneedle treatment success was achieved despite applying a dose of peanut protein 10-times lower than the dose delivered by EPIT. Researchers say the findings demonstrate the potential for peanut microneedles to improve food allergen immunotherapy through the skin.
