Abstract

The present invention provides a method and equipment for predicting neoantigen epitopes. The method for predicting neoantigen epitopes includes: (1) constructing a candidate epitope library, wherein the candidate epitope library is composed of differentially expressed peptides, and the expression differentially Peptides are peptides that differ between samples with the predetermined state and samples without the predetermined state; (2) building a predictive model based on a historical database composed of known antigenic epitope composition; and (3) using at least a subset of the candidate epitope library as an input variable of the prediction model, so as to predict new antigenic epitopes. Using this method of predicting neoantigen epitopes, it is possible to truly determine the mutation information of antigens from the gene level and protein level, and then quickly and effectively obtain neoantigen epitopes that can bind to MHC, and can accurately predict the relationship between antigen epitopes and NHC At the same time, the method is simple and convenient, and can greatly save manpower and material resources.

Description

technical field

[0001] The present invention relates to the field of biotechnology, in particular, to neoantigen epitopes and methods and applications for predicting them, more specifically, to methods and equipment for predicting neoantigen epitopes, and to determining the probability of differentially expressed peptides having the properties of epitopes Method and equipment, antigenic epitopes and their use in the preparation of medicines. Background technique

[0002] Tumors have the following ten characteristics: self-sufficient growth signals; insensitivity to anti-growth signals; avoidance of immune destruction; tumor-promoting inflammation; abnormal cellular energy; Tissue invasion and metastasis; resistance to cell death. Tumor is the most common genetic disease. All tumors originate from abnormalities in DNA sequences. Therefore, although different tumors have different causes and symptoms, they can all be explained by gene mutations. In recent years, the rapid de...
