Solution Overview

Problem

Dysregulation of bioactive molecules leads to homeostatic imbalance and disease, necessitating therapies to regulate their expression and production.

Innovation Solution

Compositions comprising recombinant plasmids encoding nucleotide sequences that upregulate the production of mRNA for target biomolecules like TLR3-Fc, TLR9-Fc, DNAse I-Fc, NGF-Fc, or insulin-Fc, administered via vectors such as AAV, protein coats, or lipid vesicles to increase endogenous production in subjects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If bioactive molecules are over-expressed, then the therapeutic effect is improved, but homeostatic imbalance and disease occur

Engineering Contradiction:
Improveproduction of target biomoleculeVSAvoidhomeostatic imbalance
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent employs inducible promoter systems that allow dynamic control of gene expression parameters. The promoter can be switched between active and inactive states based on specific physiological conditions or external inducers, enabling precise adjustment of biomolecule production levels to match therapeutic needs while avoiding harmful over-expression

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback control mechanisms where the expression of the target biomolecule is regulated based on endogenous signals or external monitoring. This allows the system to automatically adjust production levels, increasing them when therapeutic effect is needed and reducing them when homeostasis is restored, thereby preventing the harmful effects of uncontrolled over-expression

Inventive Principle:
Principle #23Feedback

2Productivity

If bioactive molecules are under-expressed, then homeostatic imbalance and disease occur, but increasing expression may cause harmful effects

Engineering Contradiction:
Improveproduction of target biomoleculeVSAvoiddisease from over-expression
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent uses targeted delivery systems that pre-position the gene expression machinery specifically at the disease site before activation. This ensures that increased biomolecule production occurs only where needed therapeutically, avoiding harmful effects in healthy tissues. The system is activated only after proper positioning and targeting confirmation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs tissue-specific or cell-specific promoters that restrict biomolecule expression to particular anatomical locations or cell types. This localizes the therapeutic effect to the affected area while leaving other tissues unaffected, thereby increasing productivity where needed without generating harmful systemic effects

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If plasmid encoding is used to upregulate mRNA production, then bioavailability of target biomolecule increases, but complexity of the composition increases

Engineering Contradiction:
Improvebioavailability of target biomoleculeVSAvoidcomplexity of plasmid composition
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent employs universal promoter elements and regulatory sequences that can control expression of different target genes using the same basic plasmid architecture. This multi-functional design reduces overall system complexity by using standardized components that can be applied across multiple therapeutic targets while maintaining high biomolecule production

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple functional elements (promoter, enhancer, terminator, selection markers) into a single integrated plasmid construct. This consolidation reduces the number of separate components needed, simplifying the overall composition while maintaining the ability to achieve high levels of mRNA and biomolecule production

Inventive Principle:
Principle #5Merging (Combining)
