Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods fail to effectively modulate cellular signaling pathways, particularly those mediated by Toll-like receptors (TLRs), which are involved in various diseases such as sepsis, autoimmune disorders, and cancer, limiting therapeutic options for these conditions.

Innovation Solution

Modulating the activity of Leucine-rich repeat and calponin homology domain-containing protein 4 (Lrch4) through expression manipulation using specific polynucleotides, antibodies, or small molecules to alter cytokine production and signaling pathways, including those of TLRs and associated proteins like MyD88 and NF-κB.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If TLR-mediated signaling pathways are activated to enhance immune response, then disease resistance improves, but excessive inflammation and tissue damage occur

Engineering Contradiction:

Improveimmune response effectivenessVSAvoidinflammatory damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Lrch4 acts as an intermediary protein that modulates TLR signaling pathways. It interacts with TLRs and downstream signaling components to fine-tune the immune response, preventing excessive activation while maintaining effective pathogen defense. This mediator approach allows balanced regulation of the signaling cascade.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention modulates key parameters of TLR signaling pathways by altering Lrch4 expression levels or activity. This changes the signaling threshold and intensity, enabling the system to respond appropriately to pathogens without triggering excessive inflammatory responses that cause tissue damage.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If Lrch4 expression is increased to enhance TLR signaling, then cytokine production improves, but uncontrolled inflammation occurs

Engineering Contradiction:

Improvecytokine productionVSAvoidinflammatory cytokines

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

Lrch4 modulation creates a feedback mechanism in TLR signaling. By regulating Lrch4 expression or activity, the system establishes control loops that monitor and adjust cytokine production levels, ensuring adequate immune response while preventing runaway inflammatory responses through negative feedback regulation.

Inventive Principle:

Principle #23Feedback

3Reliability

If conventional methods are used to modulate TLR activity, then immune response is enhanced, but therapeutic precision is insufficient

Engineering Contradiction:

Improveimmune activationVSAvoidsignaling modulation precision

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The invention applies local quality modification by specifically targeting Lrch4, a particular protein in the TLR signaling pathway, rather than broadly activating all TLR signals. This localized approach allows precise modulation of specific signaling nodes, enabling fine-tuned control over immune response intensity and duration with greater therapeutic precision.

Inventive Principle:

Principle #3Local quality
