Dynamics of an age‐structured multiscale hepatitis C virus model with two infection modes and antibody immune response
Bibliographic record
Abstract
The interference of direct‐acting antiviral agents (DAAs) within various steps of the life cycle of hepatitis C virus (HCV) results in a high cure rate for chronic HCV infection. To accurately quantify the effect of DAAs on treatment and to achieve an optimal drug combination for treatment, we formulate an age‐structured multiscale HCV model. This model incorporates intracellular virus RNA replication process corresponding to the mechanism of drug action, two modes of extracellular virus transmission (virus‐to‐cell infection and cell‐to‐cell infection), and antibody immune response. We prove that the threshold dynamics of the pre‐treatment model is completely determined by the basic reproduction number and the antibody immune reproduction number . Under reasonable assumptions, we obtain long‐term and short‐term approximations for post‐treatment viral loads and identify which approximation performs better under various scenarios. Numerical simulations show that the infection mode of cells mainly affects the reduction of viral load in the third stage, while the antibody immune response is mainly manifested in the clearance of viral particles in the first stage of viral load decrease. With effective treatments, blocking cell‐to‐cell infection and enhancing the antibody immune response can effectively reduce the viral load in a short time period achieving the eradication of infection. Our findings suggest that the HCV infection is highly dynamic post‐DAAs treatment, and early monitoring of viral load decline contributes to the implementation of subsequent treatment regimens.

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.
