Solution Overview

Problem

Current treatments targeting the LTβR signaling pathway are non-specific, making it difficult to determine which ligands and signaling pathways are responsible for regulating Treg migration, which is critical for graft survival and inflammation control, and may not effectively address conditions like graft rejection and cancer.

Innovation Solution

Development of specific inhibitors targeting either the classical or non-classical LTβR-NFκB signaling pathways using polypeptides, such as cell-penetrating peptides derived from the LTβR intracellular domain, to selectively modulate these pathways.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If non-specific treatments targeting the LTβR signaling pathway are used, then the signaling pathway is inhibited, but it is difficult to determine which ligands and signaling pathways are responsible for regulating Treg migration and the treatment may not effectively address specific conditions like graft rejection and cancer

Engineering Contradiction:
Improvespecificity of pathway inhibitionVSAvoiduncertainty about ligand and pathway responsibility
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the LTβR signaling pathway into two distinct arms: the classical NFκB pathway and the non-classical NFκB pathway. By developing selective inhibitors for each arm, the patent enables precise targeting of specific signaling components. This segmentation allows researchers to determine which ligands and pathways are responsible for regulating Treg migration, thereby resolving the uncertainty about pathway specificity while maintaining the ability to treat diverse conditions.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If selective inhibitors targeting specific LTβR-NFκB signaling pathways are developed, then Treg migration and cell motility can be precisely regulated, but the complexity of the inhibitor system increases

Engineering Contradiction:
Improveprecision of Treg migration regulationVSAvoidcomplexity of inhibitor system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by developing inhibitors with specific binding characteristics that target particular signaling pathways. The classical pathway inhibitor binds to LTβR and selectively inhibits classical NFκB signaling, while the non-classical pathway inhibitor binds to LTβR and selectively inhibits non-classical NFκB signaling. This localized targeting approach enables precise regulation of Treg migration without requiring complex combination therapies, thus achieving precision while managing system complexity.

Inventive Principle:
Principle #3Local quality

3Reliability

If both classical and non-classical LTβR-NFκB signaling pathways are inhibited, then comprehensive control over cell migration is achieved, but the risk of off-target effects and treatment side effects increases

Engineering Contradiction:
Improvecontrol over cell migrationVSAvoidoff-target effects and treatment side effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies partial action by developing selective inhibitors that target either the classical or non-classical LTβR-NFκB signaling pathway, rather than inhibiting both pathways simultaneously. This partial targeting approach allows for controlled inhibition of specific signaling arms, achieving reliable control over cell migration in specific disease contexts while minimizing off-target effects and treatment side effects that would result from comprehensive pathway inhibition.

Inventive Principle:
Principle #16Partial or excessive action
