The replicative activity of human endogenous retrovirus K102 (HERV-K102) with HIV viremia
Bibliographic record
Abstract
OBJECTIVE: To address the activation and replicative activity of HERV-K102 in vivo associated with HIV viremia. DESIGN AND METHODS: Initially serology was performed on HERV-K102 specific envelope peptides to determine if HERV-K102 may become activated with HIV viremia. Before developing a quantitative PCR (qPCR) assay, we first determined whether plasma associated particles contained DNA or RNA genomes in a pilot study which surprisingly revealed predominantly DNA genomes. A relative, ddCt qPCR ratio method was then devised to detect excess levels of HERV-K102 pol DNA templates over genomic levels which served as a surrogate marker to reliably index the level of particles found in plasma. RESULTS: Both the peptide serology and ddCt qPCR excess ratio methods suggested the activation of HERV-K102 in about 70-80% of HIV viremic cases whereas only 2-3% of normal healthy adults had marginally activated HERV-K102 (P < 0.0001). Moreover, by digestion with dUTPase we were able to confirm that the vast majority of excess DNA template in plasma related to cDNA production rather than representing genomic copies. CONCLUSIONS: Our work uniquely suggests the common activation of HERV-K102 with HIV viremia and may be first to directly demonstrate HERV-K102 cDNA production in vivo. The potential implications of the induction of HERV-K102 activation and replication for the prevention and control of HIV are discussed.

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.
