Rationale for maintenance of the M184v resistance mutation in human immunodeficiency virus type 1 reverse transcriptase in treatment experienced patients.
Bibliographic record
Abstract
The M184V substitution in HIV-1 RT develops rapidly following initiation of therapy with 3TC and confers high-level phenotypic resistance to this drug both in vitro and in vivo. Interestingly, the presence of M184V is also associated with alteration of several mechanisms relating to RT function that include decreased RTprocessivity, reduced nucleotide-dependent primer unblocking, increased fidelity, hypersensitization to other NRTIs, impaired viral fitness, and delayed appearance of mutations in RT that are responsible for resistance to thymidine analogues (i.e. thymidine-associated mutations or TAMs). In addition, M184V may affect viral transmission and immunological response. Collectively, these factors might explain the residual antiviral effect and clinical benefit observed with continued use of 3TC in combination therapy regimens following the emergence of M184V.

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.
