Solution Overview

Problem

Current treatments for neurodegenerative diseases such as Parkinson's disease and dementia with Lewy bodies are ineffective in addressing the accumulation of alpha-synuclein protein, leading to neuronal degeneration and cognitive impairment, as existing therapies fail to target the intracellular nature of Lewy bodies effectively.

Innovation Solution

Administration of antibodies specifically binding to epitopes within alpha-synuclein, such as residues 118-126, to induce an immunogenic response, either actively with immunogens or passively with antibodies, to reduce the number of inclusions in the brain, thereby treating or preventing Lewy body diseases like Parkinson's disease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing therapies are used, then treatment of neurodegenerative diseases is attempted, but they fail to effectively target intracellular Lewy bodies and reduce alpha-synuclein aggregation

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidalpha-synuclein aggregation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs antibodies as intermediary molecules that specifically bind to alpha-synuclein epitopes (such as residues 118-126). These antibodies act as mediators between the immune system and the pathogenic alpha-synuclein aggregates, enabling targeted recognition and clearance of Lewy bodies without requiring direct penetration into intracellular spaces. The antibodies facilitate immune-mediated removal of the harmful aggregates.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If antibodies are administered to induce immunogenic response, then alpha-synuclein deposits are targeted and cleared, but the complexity of the treatment approach increases

Engineering Contradiction:
Improveclearance of alpha-synuclein depositsVSAvoidtreatment approach complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages the body's own immune system to perform the therapeutic function. By administering antibodies that induce an immunogenic response, the treatment activates the patient's endogenous immune mechanisms to recognize, target, and clear alpha-synuclein deposits. This self-service approach eliminates the need for complex external intervention systems while achieving effective clearance of pathological aggregates.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If conventional treatments are used, then general symptom management is attempted, but they do not address the root cause of neuronal degeneration

Engineering Contradiction:
Improvesymptom managementVSAvoidaddressing root cause
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts and specifically targets the root pathological element - alpha-synuclein aggregates - from the complex disease process. By designing antibodies that specifically bind to epitopes on alpha-synuclein, the treatment isolates and removes the causative agent of neuronal degeneration. This extraction approach addresses the fundamental cause rather than merely managing downstream symptoms, while the antibody-based mechanism remains operationally straightforward.

AI summary

The invention provides improved agents and methods for treatment of diseases associated with synucleinopathic diseases, including Lewy bodies of alpha-synuclein in the brain of a patient. Such methods entail administering agents that induce a beneficial immunogenic response against the Lewy body. The methods are particularly useful for prophylactic and therapeutic treatment of Parkinson's disease.
