Abstract

UNLABELLED

has become the causal agent of multiple forms of gastric disease worldwide, including gastric cancer. The enzyme l-asparaginase (ASNase) has been studied as a virulence factor. In this work, we performed an in silico investigation to characterize the immunological profile of ASNase (HpASNase) to ascertain the possible implication of HpASNase immunogenicity in the virulence mechanism. We applied a workflow based on bioinformatics tools, which, by calculating the relative frequency of immunogenic T-cell and B-cell epitopes, allowed us to predict the immunogenicity and allergenicity of HpASNase in silico We also visualized the epitopes by mapping them into the native structure of the enzyme. We report for the first time the T-cell and B-cell epitope composition that contributes to the immunogenicity of this HpASNase, as well as the regions that could generate a hypersensitivity response in humans. ASNase from resulted in highly immunogenic and allergenic. The high immunogenicity of HpASNase could imply the pathogenic mechanisms of . This knowledge could be important for the development of new drugs against infections.

摘要

未标记

已成为全球多种胃病(包括胃癌)的致病因子。L-天冬酰胺酶(ASNase)作为一种毒力因子已被研究。在这项工作中,我们进行了一项计算机模拟研究,以表征幽门螺杆菌天冬酰胺酶(HpASNase)的免疫特征,以确定HpASNase免疫原性在毒力机制中的可能影响。我们应用了基于生物信息学工具的工作流程,通过计算免疫原性T细胞和B细胞表位的相对频率,使我们能够在计算机上预测HpASNase的免疫原性和致敏性。我们还通过将表位映射到酶的天然结构中来可视化表位。我们首次报告了有助于这种HpASNase免疫原性的T细胞和B细胞表位组成,以及可能在人类中产生超敏反应的区域。来自幽门螺杆菌的天冬酰胺酶具有高度免疫原性和致敏性。HpASNase的高免疫原性可能意味着幽门螺杆菌的致病机制。这些知识对于开发抗幽门螺杆菌感染的新药可能很重要。
