Humans may be genetically programmed to produce antibodies against peanut, suggests a #ScienceTranslationalMedicine study showing nonallergic people harbor convergent, germline-encoded antibodies against the allergen Ara h 2. https://scim.ag/3LqfEp9

In a #ScienceImmunology Review from earlier this year, researchers discuss how interactions between the nervous and immune systems could impact neurological disorders and allergy-related behaviors like food avoidance. https://scim.ag/3Y1hcsr

This paper by Conde et al. demonstrates that a conjugate vaccine coupling a mutated human IgE fragment to a CRM carrier induces durable, neutralizing anti-IgE autoantibodies in humanized mice, providing long-term protection against systemic and cutaneous anaphylaxis without compromising anti-helminth immunity. #ScienceTranslationalMedicine. https://scim.ag/3XxHAdi

Nature research paper: Maternal stress triggers early-life eczema through fetal mast cell programming

go.nature.com/3UPz8Vm

The causes of early-life eczema have been unclear, but evidence indicates that changes to fetal immune cells and sensory neurons during pregnancy play a key part

go.nature.com/45Y9aUQ

This paper by Shi et al. (reported by Nature) identifies that unrelated allergens trigger allergic airway inflammation across species via conserved pore-forming proteins that create membrane holes, allowing calcium influx to initiate the primary danger signals that drive the type 2 immune response.

This paper by Janssen et al. demonstrates that DOCK8 deficiency drives food allergy and oral anaphylaxis by disrupting T regulatory cell and Th17 function, causing dysbiosis and an IL-25/IL-4 cascade that expands mucosal mast cells and increases intestinal permeability.

This review by Brian Kim and David Artis details how peripheral sensory neuroimmunology has emerged as a distinct field by revealing critical interactions between the immune and sensory nervous systems that govern allergy, infection, autoimmunity, and tissue homeostasis.

Why scratching makes a rash worse and a potential benefit to scratching--it reduced S. aureus on skin. Andrew Liu's paper from our lab is out now at #science #neuroimmune #immunology www.science.org/doi/10.1126/...

Scratching a mosquito bite can offer a moment of bliss, and now scientists have learnt why: scratching activates an immune response that helps to protect the skin against harmful infections, at least in mice.

This review by Kothari and Dong outlines how bidirectional neuroimmune crosstalk—where immune signaling molecules directly activate sensory neurons and neuropeptides modulate local immune responses—drives pathologic itch, highlighting tissue-specific mechanisms and novel targetable pathways for pruritic diseases.

This paper by Dong et al. demonstrates that electroacupuncture drives a somatosensory-vagal-gastric reflex to improve gastric motility in both mice and human patients via the activation of deep fascial nociceptors and gastro-projecting vagal motor neurons.
