Abstract

fetched live from OpenAlex

Intestinal epithelial cells (IECs) are critical in the maintenance of intestinal homeostasis. Janus kinase (JAK) and signal transducers and activators of transcription (STAT)-mediated signalling coordinates the cell-cell communication underpinning many homeostatic, inflammatory, and host-defensive responses. Little is known about the role of JAK2 in IECs. To investigate the role of IEC JAK2 in homeostasis, we generated mice deficient in Jak2 using a Cre-loxP system. These mice exhibited increased intestinal barrier permeability, altered gene expression of tight junction proteins, and increases in TH2 and TH17 cytokine gene expression. Further, these mice exhibited greater histological evidence of intestinal inflammation and when subjected to experimental colitis, lost more body weight than control mice. Overall, IEC Jak2 deletion resulted in mild inflammation and impairments to the intestinal barrier, indicating IEC Jak2 may promote intestinal homeostasis.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
