Solution Overview
Problem
Current cell therapies, such as immunotherapies, face challenges due to inadequate understanding of molecular mechanisms, leading to suboptimal or inappropriate treatments and inconsistent patient responses, as existing diagnostic processes are unreliable and fail to accurately predict interactions between target and effector cells in individual patients.
Innovation Solution
A method involving the detection of proteins on cells, obtaining spatial coordinates, constructing data vectors through spatial distribution analysis, and using machine learning algorithms to classify cells and predict treatment outcomes, enabling precise selection of therapies based on cell interactions and patient-specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current diagnostic processes are used to select cell therapies, then treatment can be administered quickly, but the treatment accuracy and patient response prediction are unreliable
Solution Approach 1:
The diagnostic process is segmented into multiple analytical layers: (1) single-cell protein expression profiling, (2) spatial organization analysis of proteins within cells, (3) cell-cell interaction mapping, and (4) machine learning-based prediction. This segmentation allows comprehensive analysis while maintaining systematic manageability of the overall complex process.
Solution Approach 2:
The invention transitions from traditional one-dimensional protein expression quantification to multi-dimensional analysis by incorporating spatial coordinates (x, y positions) of proteins within cells, creating a two-dimensional spatial map. This dimensional expansion enables detection of spatial organization patterns that correlate with treatment response, significantly improving diagnostic precision.
2Loss of information
If comprehensive spatial distribution analysis is performed on protein locations, then cell interaction understanding improves, but data processing complexity and computational requirements increase
Solution Approach 1:
The system performs preliminary spatial organization analysis by calculating distance matrices and clustering proteins into functional groups before main analysis. This preliminary structuring of spatial data reduces the complexity of subsequent interaction analysis while preserving all relevant spatial information for treatment prediction.
Solution Approach 2:
Machine learning models serve as intermediaries that process complex spatial distribution data and translate it into clinically actionable predictions. The ML algorithms absorb the computational complexity of analyzing multi-dimensional spatial coordinates and protein interactions, presenting simplified treatment response predictions to clinicians.
3Reliability
If traditional protein expression levels are measured without spatial context, then measurement is simple, but the ability to predict treatment response is insufficient
Solution Approach 1:
The invention adds spatial dimensions (x, y coordinates) to traditional protein expression measurement, transforming one-dimensional expression data into two-dimensional spatial distribution maps. This enables detection of spatial patterns such as protein clustering at cell membranes or specific subcellular locations that are predictive of treatment response.
Solution Approach 2:
The analysis focuses on local spatial organization of proteins within specific regions of cells rather than only global expression levels. By examining local protein distributions and their spatial relationships with target cells, the system identifies localized molecular mechanisms that determine treatment efficacy.
