Expression of a foreign gene by cysteine proteinase null recombinant baculovirus
Bibliographic record
Abstract
The baculovirus expression vector systems (BEVS) are broadly used for producing foreign proteins in lepidopteran larvae. Most commercial BEVS are engineered to insert foreign genes into the polyhedrin (polh) locus and lack the polh gene. These viruses cannot produce occlusion bodies and are inconvenient for per os inoculation of larvae. Current knowledge in baculovirus genomics makes it possible to engineer BEVS into other parts of the virus genome. In our work, we have expressed recombinant M-HBsAg (middle surface antigen of human hepatitis B) in the baculovirus construct, rBmNPV-Deltav-cath-M-HBsAg, inserting foreign gene into the v-cath locus of the Bombyx mori nucleopolyhedrovirus (BmNPV) such that the v-cath gene is deleted and the native polh gene is retained. Silkworm larvae were infected per os and M-HBsAg was observed to be abundantly produced at a very late stage of infection.

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.
