Induction of Antiviral Response Against Avian Infectious Laryngotracheitis Virus Infection
Bibliographic record
Abstract
Toll-like receptors (TLRs) recognize pathogen associated molecular patterns (PAMPs). The PAMPs that act as ligands for TLRs prompt downstream signalling leading to antimicrobial effects. However, the details of antiviral responses of lipotechoic acid (LTA) and CpG DNA, which act as ligands for TLR-2 and -21 respectively, elicited against avian viruses are scarce. We investigated whether in ovo delivery of LTA and CpG DNA induces antiviral responses against infectious laryngotracheitis virus (ILTV) infection in chickens. We found that in ovo delivery of these two ligands reduces ILTV infections in lungs pre- and post-hatch. However, only CpG DNA could reduce mortality and morbidity due to ILTV infection encountered post-hatch. The expression of IL-1β mRNA and increase of macrophage numbers in lungs were found to be correlates of observed antiviral responses. Thus, LTA and CpG DNA can be candidate TLR ligands worthy of further investigation for the control of ILTV infection in chickens.

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.
