Abstract

BacKground: the novel coronavirus (2019-ncov, sars-cov-2, or covid-19) is a recent type of rna virus. the disease caused by the coronavirus, called COVID-19, was frst identifed in Wuhan, China. COVID-19 is a new virus and is related to families of viruses such as acute respiratory syndrome and other common colds. symptoms include fever, cough and shortness of breath. in more severe cases, the infection can lead to pneumonia, kidney failure and in some cases the disease will be fatal. there is currently no known treatment for the virus. however, insilico approaches help produce effcient novel vaccine in a short time and at low cost compared with previous methods. Methods: in this study, immunoinformatics tools was used to predict Mhc-i, Mhc-ii, ctl and B-cell epitopes of spike protein and envelope protein of SARS-CoV-2 that could be appropriate to trigger immune system response. We identifed potential epitopes against SARS-CoV-2 that could potentially stimulate both t-cell and B-cell immune system response with increased effective potential due to the presence of Mhc-i, Mhc-ii, ctl and B-cell epitopes. immunoformatics tools were used to physicochemical property analysis of the protein sequences and detect highly antigenic, non-toxin, non-allergen and highly immunogenic Mhc-i, Mhc-ii, ctl and B-cell epitopes of the spike protein and envelope protein of the 2019-ncov was performed in ProtParam, antigenpro, toxinPred, algPred, iedB, ranKPeP, ctlpred and BepiPred servers. the safety and stability of epitopes were analyzed for the binding potential with the Major histocompatibility complex (Mhc) alleles using Firedock and Patch dock tools. results: Based on the results, the best epitopes were selected. selected epitopes may be used as target candidates in recombinant vaccines to combat covid-19 virus. CONCLUSIONS: These fndings are likely to help develop the recombinant vaccine against COVID-19 disease.
