Abstract
The novel HIV-1 drugs GS-CA1 and the recently approved lenacapavir (GS-6207) target the viral structural protein capsid (CA). However, their multiple mechanisms of action have not been fully characterized. Here, we investigated the effects of GS-CA1 on the early stages of HIV-1 infection, specifically the steps involving the nuclear envelope, in comparison to the antiviral cytokine IFN-β. Mass spectrometry data indicated that nuclear envelope proteins were only modestly affected by either GS-CA1 treatment or HIV-1 infection, but combining the two had a more significant impact, altering the levels of many proteins including proteasomal components. GS-CA1 induced a small but clear accumulation of HIV-1 capsid cores at nuclear pores, as seen by microscopy, whereas IFN-β caused a strong accumulation of HIV-1 cores at the nuclear envelope but not specifically at nuclear pores. These observations are consistent with GS-CA1 inhibiting the nuclear translocation of HIV-1 capsid cores through nuclear pores.

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 it
