摘要:

B细胞表位在刺激B细胞、触发导致抗体产生的初级免疫应答以及以记忆细胞的形式建立长期免疫中起关键作用。因此,能够准确预测适当的线性B细胞表位区域将为开发新的基于蛋白质的疫苗铺平道路。了解预测的可信度对于获得临床医生对该技术的信任也至关重要。在这篇文章中,我们提出了一种深度学习中的校准不确定性估计,以使用MC-DropWeights来近似变分贝叶斯推断,从而使用来自免疫表位数据库的数据来预测表位区域。将其应用于SARS-CoV-2后,它可以比标准方法更可靠地预测B细胞表位。这将能够确定针对Covid-19的安全有效的候选疫苗。

英文摘要:

B-cell epitopes play a key role in stimulating B-cells, triggering the primary immune response which results in antibody production as well as the establishment of long-term immunity in the form of memory cells. Consequently, being able to accurately predict appropriate linear B-cell epitope regions would pave the way for the development of new protein-based vaccines. Knowing how much confidence there is in a prediction is also essential for gaining clinicians' trust in the technology. In this article, we propose a calibrated uncertainty estimation in deep learning to approximate variational Bayesian inference using MC-DropWeights to predict epitope regions using the data from the immune epitope database. Having applied this onto SARS-CoV-2, it can more reliably predict B-cell epitopes than standard methods. This will be able to identify safe and effective vaccine candidates against Covid-19.
