Folate Receptor Alpha Polypeptide Compositions for Immune Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective means to assess and stimulate immunity to folate receptors, particularly in cancer patients, which is crucial for prognosis and treatment, as folate receptor α (FRα) is overexpressed in various cancers and associated with tumor aggressiveness.
Innovation Solution
Development of compositions containing specific polypeptides such as FR5, FR12, FR30, FR56, FR76, FR113, FR138, FR147, and others to assess and stimulate immunity to folate receptors, including the use of adjuvants to enhance immune responses in cancer patients.

Engineering Contradiction Analysis
1Reliability
If polypeptide compositions are used to stimulate immunity to folate receptors, then immune response against cancer is improved, but the complexity of treatment protocols increases
Solution Approach 1:
The folate receptor polypeptide is divided into multiple epitope peptides (FR5, FR12, FR30, FR56, FR76, FR95, FR113, FR120, FR138, FR147, FR152, FR156, FR225, FR238), each targeting specific immune responses. This segmentation allows the complex immune stimulation task to be divided into manageable peptide components that can be individually optimized and combined in vaccine formulations.
Solution Approach 2:
The invention combines multiple epitope peptides with adjuvants to create composite vaccine compositions. These composite materials integrate different functional components (antigenic peptides + immune-enhancing adjuvants) to achieve synergistic immune stimulation while maintaining a structured, manageable formulation approach.
2Measurement precision
If multiple epitope peptides are used to assess immunity, then measurement precision of immune response is improved, but the complexity of diagnostic procedures increases
Solution Approach 1:
The diagnostic approach segments the immune response assessment by testing for specific epitope peptide antibodies (FR5, FR12, FR30, etc.) rather than measuring overall folate receptor antibodies. This segmentation enables precise identification of which specific tumor epitopes have elicited immune responses, providing detailed prognostic information through manageable individual assays.
Solution Approach 2:
The epitope peptide compositions serve multiple functions: they can be used individually or in combination for diagnostic testing, for vaccine formulation, and for assessing immune response to different tumor types. This multi-functionality reduces the need for separate specialized assays for different applications.
