Solution Overview

Problem

Current treatments for Parkinson's disease and other neurodegenerative disorders lack effective neuroprotective agents to prevent dopaminergic neuron degeneration, with existing growth factors showing variable efficacy and potential amino acid sequence errors in previous studies on MANF.

Innovation Solution

Characterization of the mesencephalic-astrocyte-derived neurotrophic factor (MANF) and its genetic sequence, along with recombinant production methods, to develop therapeutic and diagnostic tools for MANF-dependent conditions, including pharmaceutical compositions and gene therapy applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If GDNF is used to protect dopaminergic neurons in Parkinson's disease, then neuronal survival is improved, but clinical efficacy remains controversial and variable

Engineering Contradiction:
Improveneuroprotective efficacyVSAvoidclinical response variability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a corrected copy of the MANF protein sequence (correcting the amino acid substitution at position 176 from proline to arginine) to ensure accurate replication of the native protein's neuroprotective function, thereby improving reliability while reducing variability in clinical response

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent modifies the amino acid sequence parameter at position 176 (changing from proline to arginine) to correct the sequence error identified in previous studies, ensuring the MANF protein maintains its intended neuroprotective properties and reduces clinical variability

Inventive Principle:
Principle #35Parameter changes

2Productivity

If MANF polypeptide with amino acid substitution at position 176 is used in previous studies, then experimental results were obtained, but the results are not relevant to the true MANF function due to sequence error

Engineering Contradiction:
Improveresearch outputVSAvoidsequence accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent provides the correct amino acid sequence of MANF (with arginine at position 176) as an accurate reference copy, enabling future research to produce relevant and meaningful results by using the true native sequence rather than the erroneous substituted version

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent corrects the amino acid sequence parameter at position 176 from proline to arginine, thereby improving measurement precision and ensuring that subsequent research using this corrected sequence will yield accurate and relevant findings about MANF's true neuroprotective function

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If new neurotrophic factors are identified and characterized, then therapeutic options for neurodegenerative disorders are expanded, but development time and resource investment increase

Engineering Contradiction:
Improvetherapeutic optionsVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary characterization of the MANF protein sequence, expression patterns, and neuroprotective function in advance, establishing a solid foundation that accelerates future therapeutic development by eliminating the need for repetitive basic research on MANF's fundamental properties

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent provides complete nucleic acid and amino acid sequences of MANF as reusable reference copies, enabling other researchers to quickly replicate and build upon these findings without having to perform time-consuming sequence determination and characterization from scratch

Inventive Principle:
Principle #26Copying
