In response to the ongoing COVID-19 pandemic, the global effort to develop high efficacy countermeasures to control the infection are being conducted at full swing. While the efficacy of vaccines and coronavirus drugs are being tested, the microbiome approach represents an alternative pathophysiology-based approach to prevent the severity of the infection. In the current study, we evaluated the action of a novel probiotic Probio-88 against SARS-COV-2 replication and immune regulation using an in vitro and in silico study. The results showed that extract from this strain (P88-CFS) significantly inhibited the replication of SARS-COV-2 and the production of reactive oxygen species (ROS) levels. Furthermore, compared with infected cells, P88-CFS treated cells showed a significant reduction in inflammatory markers such as IFN-α, IFN-β, and IL-6. Using an in silico molecular docking approach, it was postulated that the antiviral activity of Probio-88 was derived from plantaricin E (PlnE) and F (PlnF). The high binding affinity and formation of hydrogen bonding indicated that the association of PlnE and PlnF on SARS-COV-2 helicase might serve as a blocker by preventing the binding of ss-RNA during the replication of the virus. In conclusion, our study substantiated that P88-CFS could be used as an integrative therapeutic approach along with vaccine to contain the spread of the highly infectious pathogen and possibly its variants.
为应对持续的新冠疫情,全球正在全力开展研发高效防控措施以控制感染的工作。在对疫苗和新冠病毒药物的疗效进行测试的同时,微生物组方法代表了一种基于病理生理学的预防感染严重性的替代方法。在本研究中,我们使用体外和计算机模拟研究评估了新型益生菌Probio-88对SARS-CoV-2复制和免疫调节的作用。结果表明,该菌株的提取物(P88-CFS)显著抑制了SARS-CoV-2的复制以及活性氧(ROS)水平的产生。此外,与感染细胞相比,经P88-CFS处理的细胞中炎症标志物如IFN-α、IFN-β和IL-6显著减少。使用计算机模拟分子对接方法推测,Probio-88的抗病毒活性源自植物乳杆菌素E(PlnE)和F(PlnF)。高结合亲和力和氢键的形成表明,PlnE和PlnF与SARS-CoV-2解旋酶的结合可能通过在病毒复制过程中阻止单链RNA的结合而起到阻断作用。总之,我们的研究证实,P88-CFS可与疫苗一起用作综合治疗方法,以遏制这种高传染性病原体及其可能变体的传播。
