Solution Overview

Problem

Current therapeutic approaches for alcoholic liver disease (ALD) are inadequate due to the complex immunological and anatomical uniqueness of the liver, with a lack of effective methods to halt the progression of inflammation and tissue damage caused by excessive alcohol consumption.

Innovation Solution

Administering a composition comprising an NKT-2 activator, such as miltefosine, and sulfatide to activate type II NKT cells, which inhibits the activation of type I NKT cells, thereby reducing inflammation and tissue damage in conditions like ALD.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional therapeutic approaches are used for alcoholic liver disease, then treatment is provided, but the progression of inflammation and tissue damage is not effectively halted

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidinflammation and tissue damage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent uses type II NKT cells as intermediary agents to mediate the therapeutic effect. These cells are activated by the composition (containing sulfatide and/or NKT-2 activator) and then exert their protective function by suppressing type I NKT cell-mediated damage, thereby indirectly protecting liver tissue from inflammation and damage caused by alcohol consumption

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The treatment works by activating type II NKT cells in advance to suppress the harmful effects of type I NKT cells before they can cause significant tissue damage. The composition is administered to pre-activate protective immune cells, creating a preliminary anti-action against the harmful inflammatory response that would otherwise be triggered by alcohol-induced stress

Inventive Principle:
Principle #9Preliminary anti-action

2Reliability

If type I NKT cells are activated, then immune response is enhanced, but type I NKT cell-mediated tissue damage occurs

Engineering Contradiction:
Improveimmune responseVSAvoidtissue damage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent employs type II NKT cells as a counterbalancing force against type I NKT cells. By activating type II NKT cells through the composition, they exert a suppressive effect on type I NKT cell activity, creating an immune balance where the protective response counterweights the harmful tissue-damaging response

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

Type II NKT cells serve as intermediary regulators that modulate the activity of type I NKT cells. Rather than directly blocking type I NKT cell activation, the activated type II NKT cells intervene to suppress their harmful effects, providing a nuanced immune regulation mechanism

Inventive Principle:
Principle #24Intermediary (Mediator)
