The in vivo effects of recombinant bovine herpesvirus-1 expressing bovine interferon-γ
Bibliographic record
Abstract
To study the biological relevance of using bovine herpesvirus-1 (BHV-1) as a vector for expressing cytokines, a BHV-1 virus that expressed bovine interferon-gamma (IFN-gamma) was constructed. This recombinant virus (BHV-1/IFNgamma) was then used to infect the natural host in a respiratory disease model. In vitro characterization of the recombinant interferon-gamma confirmed that the cytokine expressed in BHV-1-infected cells was biologically active. The in vivo effects of the recombinant IFN-gamma were then analysed during a primary infection and after reactivation of a latent infection. During the primary infection, similar body temperature, clinical responses and virus shedding were observed for calves infected with either recombinant BHV-1/IFNgamma or parental gC(-)/LacZ(+) virus. An analysis of cellular and humoral responses did not reveal any significant immunomodulation by BHV-1/IFNgamma during the primary infection. The stability and activity of recombinant IFN-gamma was also analysed following the establishment of a latent infection. The presence of recombinant IFN-gamma did not significantly alter virus shedding following reactivation. The isolation of reactivated BHV-1/IFNgamma virus confirmed that a functional IFN-gamma gene was retained during latency. Thus, herpesviruses may provide virus vectors that retain functional genes during latency and recrudescence.

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.
