Solution Overview
Problem
Existing immunotherapeutics face challenges in uniformly inducing the intended immune response and are costly to produce, lacking a systematic approach for peptide design that balances immunogenicity and synthesis ease.
Innovation Solution
A peptide unit comprising 23mer to 71mer peptides, including at least one Th epitope and one B-cell epitope, designed to induce humoral immunity, with specific lengths and configurations to ensure uniform antibody production and low production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing immunotherapeutics are used to induce immune response, then antibody production is achieved, but the immune response is not uniform and production costs are high
Solution Approach 1:
The peptide is divided into multiple epitope units (Th epitope and B-cell epitope) with specific length ranges (Th epitope: 8-32mer, B-cell epitope: 3-20mer). This segmentation allows systematic design of immunotherapeutics that uniformly induce the intended immune response while maintaining ease of synthesis through modular peptide construction.
2Reliability
If peptide length is increased to improve immunogenicity, then antibody induction capability is enhanced, but synthesis complexity and cost increase
Solution Approach 1:
The patent specifies optimal parameter ranges for peptide design: Th epitope length (8-32mer) and B-cell epitope length (3-20mer). By optimizing these parameters, the invention achieves high immunogenicity while maintaining reasonable synthesis complexity and cost.
3Loss of time
If peptide design lacks systematic approach, then development time is reduced, but immunogenicity and synthesis ease cannot be balanced
Solution Approach 1:
The patent establishes predetermined epitope unit structures with specific length ranges and composition requirements before actual peptide synthesis. This preliminary systematic design framework enables efficient development while ensuring optimal balance between immunogenicity and synthesis ease.
