Human Immunodeficiency Virus (HIV)–Specific Effector CD8 T Cell Activity in Patients with Primary HIV Infection
Bibliographic record
Abstract
The interferon-gamma ELISPOT assay was used to assess and compare the magnitude and breadth of human immunodeficiency virus (HIV)-specific CD8 T cell responses in treatment-naive subjects during the first year of HIV primary infection and during the chronic phase of infection. Twenty-five subjects tested within a year of exposure to HIV resulting in seroconversion and 20 subjects with chronic infection were screened for HIV peptide-specific activity by stimulating peripheral blood mononuclear cells with a panel of 5-21 HLA class I-restricted HIV peptides (mean, 11.2 +/- 3.5 HIV peptides). There was a significant correlation between the magnitude and breadth of HIV-specific effector responses and time elapsed from exposure (r=0.63 for magnitude vs. time and r=0.64 for breadth vs. time; P<.02, paired t test). Maximal breadth of the HIV gene product reactivity was achieved within 2 months of exposure for Nef-specific responses and by 4 months of exposure for responses directed to Env, Gag, and reverse transcriptase.

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.
