HIV‐1 Replication Is Stimulated by Sodium Stibogluconate, the Therapeutic Mainstay in the Treatment of Leishmaniasis
Bibliographic record
Abstract
Leishmaniasis is an important opportunistic disease among patients infected with human immunodeficiency virus (HIV)-1. The pentavalent antimony compound sodium stibogluconate is a drug of choice for the treatment of leishmaniasis. Because sodium stibogluconate acts as an inhibitor of phosphotyrosyl phosphatases and such inhibitors can promote HIV-1 replication, we tested the effect of this compound on virus gene expression. Using pseudotyped reporter viruses and fully infectious laboratory-adapted and clinical strains of HIV-1, we report that sodium stibogluconate induces an increase in HIV-1 transcription and virus replication in primary CD4(+) T cells and in thymic histocultures. This activation is a slow process and appears to involve the transcription factors nuclear factor- kappa B and activator protein 1, as well as the Syk, Jun, and mitogen-activated protein kinase/extracellular signal-related kinase signal-transduction pathways. In addition, the effect seems to be partly mediated by a soluble factor. Altogether, these findings might reveal clinical implications for the treatment of leishmaniasis in HIV-1-infected patients.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
