Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective tools for precisely determining the factors involved in epidermal homeostasis, particularly in the proliferation and differentiation of skin cells, and for screening active compounds that can modulate these processes in a rapid, sensitive, and cost-effective manner.
Innovation Solution
Isolated peptides derived from Filaggrin-2 and SASPase, which form a complex capable of modifying their three-dimensional conformation, are used to screen compounds that regulate skin cell proliferation and differentiation, employing specific amino acid sequences and nucleic acid sequences with at least 85% identity for affinity binding and modulating proteolytic activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to study epidermal homeostasis, then general knowledge about skin function can be obtained, but precise determination of specific factors involved in cell proliferation and differentiation cannot be achieved
Solution Approach 1:
The invention segments the complex epidermal homeostasis system into specific molecular components by identifying and isolating the SASPase-FLG2 complex. This segmentation allows precise study of individual factors (SASPase and Filaggrin-2) and their interactions, enabling determination of specific factors involved in cell proliferation and differentiation without needing to analyze the entire complex system at once.
Solution Approach 2:
The invention introduces a fluorescent probe as an intermediary molecule that binds specifically to the SASPase-FLG2 complex. This intermediary enables detection and screening of compounds that modulate the complex's activity or conformation, providing a sensitive and specific tool for identifying factors involved in epidermal homeostasis with high precision.
2Reliability
If comprehensive screening of active compounds is performed to identify modulators of epidermal cell processes, then effective cosmetic or therapeutic agents can be found, but the screening process becomes time-consuming and expensive
Solution Approach 1:
The invention replaces complex, time-consuming biological assays with a fluorescent-based detection system. Instead of performing lengthy experiments to observe effects on cell proliferation and differentiation, the screening process uses fluorescent signal changes to rapidly identify compounds that modulate the SASPase-FLG2 complex, dramatically reducing screening time while maintaining reliability.
Solution Approach 2:
The invention utilizes changes in fluorescent parameters (intensity, wavelength, polarization) as the SASPase-FLG2 complex interacts with modulating compounds. By monitoring these parameter changes, the system can rapidly identify active compounds based on their ability to alter the complex's conformation or activity, enabling fast and reliable screening without extensive time investment.
