Viral systems such as wild-type viruses, viral vectors, and virus-like particles are essential components of modern biotechnology and medicine. Despite their importance, the commercial-scale production of viral systems remains highly inefficient for multiple reasons. Computational strategies are a promising avenue for improving process development, optimization, and control, but require a mathematical description of the system. This article reviews mechanistic modeling strategies for the production of viral particles, both at the cellular and bioreactor scales. In many cases, techniques and models from adjacent fields such as epidemiology and wild-type viral infection kinetics can be adapted to construct a suitable process model. These process models can then be employed for various purposes such as in-silico testing of novel process operating strategies and/or advanced process control.
病毒系统,如野生型病毒、病毒载体和类病毒颗粒,是现代生物技术和医学的重要组成部分。尽管它们很重要,但由于多种原因,病毒系统的商业规模生产仍然效率低下。计算策略是改进工艺开发、优化和控制的有前途的途径,但需要对系统进行数学描述。本文综述了用于生产病毒颗粒的机制建模策略,包括细胞和生物反应器尺度。在许多情况下,可以从流行病学和野生型病毒感染动力学等相邻领域的技术和模型进行改编,以构建合适的过程模型。然后可以将这些过程模型用于各种目的,例如新型过程操作策略的计算机模拟测试和/或先进的过程控制。
