Solution Overview

Problem

Existing treatments do not effectively address the role of active sulfur molecules in T cell immune responses and their application in clinical practice for inflammatory bowel diseases and type 2 airway inflammations.

Innovation Solution

A pharmaceutical composition containing persulfides, such as glutathione trisulfide, is administered to regulate CD4+ T cell activation and proliferation, thereby treating or preventing inflammatory bowel diseases and type 2 airway inflammations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional anti-inflammatory treatments are used, then inflammation symptoms are suppressed, but they do not effectively address the role of active sulfur molecules in T cell immune responses

Engineering Contradiction:
Improveeffectiveness in addressing T cell immune responseVSAvoidapplication scope in inflammatory diseases
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a novel parameter - active sulfur molecules (specifically persulfides like GSSSG) - to modulate T cell immune responses. This changes the biochemical parameter space by introducing sulfur-based compounds that specifically target CD4+ T cell activation and proliferation pathways, thereby addressing the effectiveness gap in conventional treatments while maintaining broad adaptability to various inflammatory conditions

Inventive Principle:
Principle #35Parameter changes

2Productivity

If active sulfur molecules are administered to suppress CD4+ T cell proliferation, then inflammatory bowel diseases and type 2 airway inflammations are treated, but the mechanism is not yet fully understood

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidunderstanding of molecular mechanism
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent establishes preliminary findings that active sulfur molecules suppress CD4+ T cell proliferation and differentiation into pathogenic subsets before fully elucidating the molecular mechanism. This preliminary action demonstrates therapeutic efficacy in inflammatory bowel diseases and type 2 airway inflammations, providing a foundation for further mechanistic studies while already delivering clinical benefits

Inventive Principle:
Principle #10Preliminary action
