“A dysregulated intestinal microbiome has been linked to development of food allergy, suggesting that approaches to manipulate the microbiome may have a therapeutic value. Here, Rachid et al. investigated whether fecal microbiome transplantation (FMT) could increase tolerance to peanuts in adults with peanut allergies. Of 15 patients recruited to this phase 1 clinical trial, 6 exhibited a response, where more peanut was required to elicit an allergic reaction than before the study start.”
