The role of selectins and integrins in adenovirus vector-induced neutrophil recruitment to the liver
Bibliographic record
Abstract
Adenovirus vectors for human gene therapy induce early host inflammatory responses in transduced tissues that limit gene transfer efficiency and can result in significant morbidity. The present study aimed to elucidate the cellular mechanisms underlying the acute inflammation induced by adenovirus vectors in the liver. Leukocyte rolling and adhesion in response to an intravenously administered adenovirus vector was examined by intravital microscopy in mouse liver. Adenovirus vectors significantly increased leukocyte rolling and adhesion in the postsinusoidal venules within minutes of transduction. Unlike other inflammatory states in the liver, no leukocyte retention was seen in the sinusoids in response to adenovirus vector administration. Inhibition of P-selectin, alpha(4)-integrin, and E-selectin was necessary to completely block leukocyte rolling and subsequent adhesion. The administration of an anti-alpha(4)-integrin antibody alone significantly reduced leukocyte adhesion. In contrast, adenovirus vector-induced leukocyte adhesion was unchanged in CD18-knockout mice. Depletion of circulating neutrophils eliminated leukocyte rolling and adhesion in response to adenovirus vector transduction in the liver. In conclusion, adenovirus vectors induce rapid neutrophil-mediated inflammation in the post-sinusoidal venules by selectins and alpha(4)-integrin but surprisingly not by CD18.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
