Solution Overview

Problem

Current therapies for immune-related and inflammatory diseases are inadequate, and there is a need for more effective treatments and animal models that accurately mimic human immune responses to develop immunomodulatory therapies, particularly for diseases mediated by the IL-23/17 signaling pathways.

Innovation Solution

The use of antisense oligomers targeting the IL-23/17 signaling pathways, specifically morpholino antisense oligomers that induce exon-skipping of the IL-17RC pre-mRNA transcript, modulating IL-17 signaling activity and inflammation, and administered to treat conditions such as viral hemorrhagic fever and other inflammatory diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional therapies are used for immune-related and inflammatory diseases, then treatment is provided, but the therapies are inadequate and do not effectively modulate IL-17 and IL-23 signaling pathways

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidpathway specificity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent uses antisense oligomers as intermediary molecules that specifically bind to and modulate IL-17 and IL-23 signaling pathway components. These oligomers act as mediators between the therapeutic agent and the target pathway, providing both effectiveness and pathway specificity by selectively interfering with key signaling molecules in the IL-17/IL-23 axis without broadly suppressing immune function.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention changes the therapeutic parameter from non-specific immune suppression to specific pathway modulation by using antisense oligomers that target particular mRNA transcripts in the IL-17/IL-23 signaling pathway. This allows precise control over which pathway components are inhibited, achieving both therapeutic effectiveness and pathway adaptability.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If animal models are used to develop immunomodulatory therapies, then disease research is enabled, but the models do not accurately mimic human immune responses

Engineering Contradiction:
Improvemodel accuracyVSAvoidtherapeutic translation
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by using antisense oligomers that specifically target human-derived IL-17 and IL-23 pathway components. This allows the creation of more accurate animal models where human-specific pathway elements are selectively modulated, improving model accuracy while maintaining the ability to translate findings to human therapeutic responses.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If broad immune suppression is used to treat inflammatory diseases, then inflammation is reduced, but specificity for IL-17 and IL-23 pathways is lost

Engineering Contradiction:
Improveinflammatory responseVSAvoidpathway selectivity
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The invention extracts and isolates the specific IL-17 and IL-23 pathway components from the broader immune system by using antisense oligomers that selectively target these pathways. This allows reduction of harmful inflammatory responses while preserving other immune functions, achieving both anti-inflammatory effect and pathway selectivity through targeted molecular interference.

Inventive Principle:
Principle #2Taking out (Extraction)
