项目摘要

The present project aims to establish theoretical bases on an alternative AIDS treatment for ART, which simultaneously administers multiple anti-HIV drugs to an AIDS patient. It is well known that HIV-1 is frequently-mutated. The alternative AIDS treatment is by inducing excess mutations to HIV-1 RNA(+) genome, to drive HIV-1 quasi-species population to self-destruction. Namely it uses the HIV-1error-prone character as an underhanded way. This project proposes a novel HIV-1 mathematical model considered viral kinetic processes such as mutation, replication, infection and mutagenic activities to control HIV-1 mutation rate. Numerical simulations of the model show that enhancement of a HIV-1 mutation rate causes an “error catastrophe”to HIV-1 quasi-species population. Furthermore, analyses of local asymptotic stability of the self-destruction state reveal that the alternative AIDS treatment haseffectiveness under certain specific viral conditions.
本项目旨在为ART的替代性艾滋病治疗建立理论基础,ART同时向艾滋病患者施用多种抗HIV药物。众所周知,HIV-1是经常突变的。另一种艾滋病治疗方法是通过诱导HIV-1 RNA(+)基因组的过量突变,驱使HIV-1准种群体自我毁灭。也就是说,它利用HIV-1容易出错的特性作为一种阴险的方式。本研究提出一种新的HIV-1数学模型,该模型考虑了病毒的突变、复制、感染和诱变等动力学过程,以控制HIV-1的突变率。数值模拟结果表明,HIV-1突变率的提高会导致HIV-1准种种群的“错误灾难”。此外,对自毁状态的局部渐近稳定性的分析表明,艾滋病的替代治疗在某些特定的病毒条件下是有效的。
