通过病毒学突触的细胞到细胞的病毒传播被认为通过细胞的多次感染降低了病毒群体对抗病毒药物的易感性,有助于治疗期间的低水平病毒持续性。使用一个数学框架,我们研究的作用,突触传递的治疗敏感性。一个关键因素是单个病毒粒子在无病毒和突触传递期间感染细胞的相对概率,这是一个目前未知的量。如果无病毒传播的感染概率较高,那么如果每个突触转移一种病毒,则治疗易感性最低,并且细胞的多次感染增加易感性。在相反的情况下,对于每个突触转移的中间数量的病毒体,治疗敏感性最小化。因此,通过突触的多重感染并不简单地降低治疗敏感性。在没有进一步实验研究的情况下,我们不能得出结论,突触传递为病毒在抗病毒治疗期间以低水平持续存在提供了额外的机制。
Cell-to-cell viral transmission via virological synapses has been argued to reduce susceptibility of the virus population to anti-viral drugs through multiple infection of cells, contributing to low-level viral persistence during therapy. Using a mathematical framework, we examine the role of synaptic transmission in treatment susceptibility. A key factor is the relative probability of individual virions to infect a cell during free-virus and synaptic transmission, a currently unknown quantity. If this infection probability is higher for free-virus transmission, then treatment susceptibility is lowest if one virus is transferred per synapse, and multiple infection of cells increases susceptibility. In the opposite case, treatment susceptibility is minimized for an intermediate number of virions transferred per synapse. Hence, multiple infection via synapses does not simply lower treatment susceptibility. Without further experimental investigations, one cannot conclude that synaptic transmission provides an additional mechanism for the virus to persist at low levels during anti-viral therapy.
