Systems and methods for training machine learning models are described. The methods may comprise, e.g., receiving a first plurality of images of tissue specimens stained with a histochemical stain; receiving a second plurality of images of the tissue specimens stained with an immunohistochemical stain; aligning corresponding pairs of images; segmenting the aligned corresponding pairs of images to generate first and second pluralities of segmented images; mapping segments in each segmented image of the first plurality to corresponding segments in an image of the second plurality; and generating labeled image data by labeling segments in the images of the first plurality as exhibiting a specified cellular feature (or biomarker) based on detection of a signal associated with the immunohistochemical stain. In some instances, the labeled image data can be used to train a machine learning model for a digital pathology application, e.g., the evaluation of colitis severity.

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.

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.

Resumen de: WO2026150017A1
The present invention relates to a method to predict the sensitivity of a subject to emulsifiers. Here, the inventors explored the use of an in vitro microbiota system and metagenome-based bioinformatic modeling to predict CMC sensitivity of a given microbiota. They found that CMC sensitivity associated with a unique metagenomic signature, supporting the notion that emulsifier sensitivity could be predicted from metagenomic data. They next confirmed that microbiotas predicted to be CMC-sensitive conferred CMC sensitivity when transplanted into colitis-prone IL-10-/- germfree mice. This approach validated the ability of an ex vivo approaches to predict CMC-sensitivity, thereby advancing development of microbiota- based personalized nutrition strategies. Thus, the present invention relates to a method to predict the sensitivity of a subject to emulsifiers comprising determining in a sample obtained from the subject the relative abundance of the microbiota-derived DNA markers listed in the Table A.
