METHODS, KITS AND COMPOSITIONS FOR THE TREATMENT OF FOOD PROTEIN INDUCED ENTEROCOLITIS SYNDROME AND IRRITABLE BOWEL SYNDROME

Resumen de: US20260209366A1

This invention describes methods, kits, and compositions for treating Food Protein-Induced Enterocolitis Syndrome (FPIES) and a food-triggered endotype of IBS by modulating the IL-4/IL-13→IL-4Rα axis and/or the OX40-OX40L costimulatory pathway, with patient selection and monitoring guided by blood biomarkers (elevated OX40L on dendritic cells and/or OX40 on lymphocytes, including food antigen-stimulated assays). In case examples, IL-4Rα blockade (e.g., dupilumab) produced rapid, durable clinical remission with successful food reintroduction, accompanied by reduced dendritic-cell OX40L and modulation of circulating CRTH2+ Tc2 cells, whereas OX40L-low, non-food-trigger IBS showed no response—supporting a biomarker-defined responder population. Collectively, this invention demonstrates a precision framework in which IL-4Rα and OX40/OX40L antagonists—alone or in combination—enable diet liberalization and induce tolerance in FPIES and food-triggered IBS.

METHOD FOR EXAMINING INFLAMMATORY BOWEL DISEASE AND METHOD FOR SCREENING THERAPEUTIC AGENT

Resumen de: WO2026155051A1

The present invention provides an examination method for identifying a biomarker capable of detecting the remission phase of an inflammatory bowel disease, and assisting in the diagnosis of the inflammatory bowel disease, the monitoring of disease progression, or the determination of therapeutic effect.　Focusing attention on myeloid immune cells that play an important role in the pathogenesis of inflammatory bowel disease, the present inventors considered that young myeloid immune cells potentially increase even in the remission phase and may induce transition to the active phase by progression of the disease. The present inventors then proceeded with intensive studies thereon. As a result, the present inventors found that CD11b, CD33, and CD84-positive (CD11b+CD33+CD84+) cells, which are precursor cells of myeloid immune cells, can serve as blood markers for inflammatory bowel disease. Further investigation revealed that Membrane-Spanning 4-Domains A3 (Ms4a3)-positive (Ms4a3+) cells, and Ms4a3 and CD84-positive (Ms4a3+CD84+) cells significantly increase not only in the active phase but also in the remission phase, and are significantly greater in number in the active phase than in the remission phase.

METHOD TO PREDICT SENSITIVITY TO EMULSIFIER

Resumen de: WO2026150017A1

The present invention relates to a method to predict the sensitivity of a subject to emulsifiers.
