Peripheral blood monocytes (PBMCs) display innate antiviral response to rhinovirus (RV) infected bronchial epithelial cells (133.44)
Bibliographic record
Abstract
Abstract Rhinovirus (RV) infection is an important trigger of acute asthma and COPD. Study objectives; were to characterise the response of PBMCs and CD8 lymphocytes when exposed to RV infected bronchial epithelial cells. Methods; Human Calu3 cells were used as a model for bronchial epithelial cells and infected with RV-43 and RV-1B. PBMCs were obtained from healthy individuals and separated by Ficoll-Paque centrifugation. CD8 lymphocytes were identified as CD3+, CD8+ by flow cytometry. PBMCs were exposed to infected Calu3 cells, cells exposed to UV inactive RV, PHA and TLR3 agonist PolyI:C. Response was measured by ELISA for release of interferon(IFN)-γ and TNF-α. CD8 activation with expression of perforin or proliferation measured by carboxyfluorescein succinimidyl ester assay. Results: Exposure of PBMCs to Calu3 cells infected with both RV led to significant release of IFN-γ and TNF-α, smaller release was seen in response to UV inactive RV. Exposure to PolyI:C also led to a similar release. CD8+ cells were found to be the primary source of IFN-γ release. CD8+ cells did not show an increase in perforin expression or evidence of proliferation. Conclusions; exposure of PBMCs and CD8+ cells to an RV infected bronchial epithelium alone results in an innate immune response mediated by TLR3 without evidence of a CD8 adaptive immune response.

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.
