Inhibition of GPR 55 improves dysregulated immune response in experimental sepsis
Bibliographic record
Abstract
Sepsis is a medical condition caused by dysregulated systemic inflammatory response against infection, resulting in high mortality. Despite intensive research over the last few decades, the results from multiple clinical trials targeting specific inflammatory mediators have been disappointing. In the present study, we investigated the role of G protein-coupled receptor GPR55 modulation on immune response in an experimental sepsis model (endotoxemia). Immune response was evaluated by analyzing leukocyte-endothelial interactions and capillary perfusion in the intestinal microcirculation using intravital microscopy. In addition, the levels of plasma inflammatory cytokines were measured. The results demonstrated that GPR55 inhibition using antagonists, CID16020046 or O-1918, significantly reduced leukocyte adherence in intestinal submucosal venules and decreased proinflammatory cytokine TNF-α and IL-6 production. These data suggest that GPR55 inhibition may be a novel therapeutic target for attenuating hyperinflammation during sepsis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
