is mainly responsible for sepsis, urethritis, and respiratory tract infections. These bacteria may affect the transcription of the host and particularly their immune system by producing changes in their epigenetics. In the present study, four proteins of were used to predict the epitopes for the construction of an mRNA vaccine against infections. In order to generate cellular and humoral responses, various immunoinformatic-based approaches were used for developing the vaccine. The molecular docking analysis was performed for predicting the interaction among the chosen epitopes and corresponding MHC alleles. The vaccine was developed by combining epitopes (thirty-three total), which include the adjuvant Toll-like receptor-4 (TLR4). The constructed vaccine was analyzed and predicted to cover 99.2% of the global population. Additionally, in silico immunological modeling of the vaccination was also carried out. When it enters the cytoplasm of the human (host), the codon is optimized to generate the translated mRNA efficiently. Moreover, the peptide structures were analyzed and docked with TLR-3 and TLR-4. A dynamic simulation predicted the stability of the binding complex. The assumed construct was considered to be a potential candidate for a vaccine against infections. Hence, the proposed construct is suitable for in vitro analyses to validate its effectiveness.
主要负责败血症、尿道炎和呼吸道感染。这些细菌可能通过改变宿主的表观遗传学来影响宿主的转录,尤其是其免疫系统。在本研究中,使用了四种蛋白质来预测表位,以构建针对感染的mRNA疫苗。为了产生细胞和体液反应,采用了各种基于免疫信息学的方法来开发疫苗。进行分子对接分析以预测所选表位与相应MHC等位基因之间的相互作用。通过组合表位(总共33个)来开发疫苗,其中包括佐剂Toll样受体4(TLR4)。对构建好的疫苗进行分析,预计可覆盖全球99.2%的人群。此外,还进行了疫苗接种的计算机模拟免疫建模。当它进入人(宿主)的细胞质时,密码子被优化以有效地产生翻译后的mRNA。此外,对肽结构进行了分析,并与TLR-3和TLR-4进行对接。动态模拟预测了结合复合物的稳定性。假定的构建体被认为是针对感染的疫苗的潜在候选物。因此,所提出的构建体适用于体外分析以验证其有效性。
