Neuroprotective Peptides MANF CDNF Sensory Cell Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mis-regulation of cell death leads to various sensory impairments, including hearing loss, vision loss, and olfactory and gustatory dysfunctions, with existing therapies lacking effective solutions for ototoxicity and retinal degenerative diseases.
Innovation Solution
Administration of neuroprotective peptides, such as mesencephalic astrocyte-derived neurotrophic factor (MANF) or conserved dopamine neurotrophic factor (CDNF), or their fragments, to prevent or treat cell death-related sensory impairments through topical, systemic, or intratympanic routes, potentially combined with viral expression vectors or MANF modulators like valproic acid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing therapies are used for sensory loss, then treatment is provided, but they lack effective solutions for ototoxicity and retinal degenerative diseases
Solution Approach 1:
The patent applies universality by developing a single therapeutic approach using neuroprotective peptides (MANF and CDNF) that can treat multiple types of sensory loss including ototoxicity, retinal degenerative diseases, noise-induced hearing loss, and age-related hearing loss. This multi-functional peptide therapy replaces the need for separate targeted therapies for each condition.
2Reliability
If neuroprotective peptides are administered to prevent cell death, then sensory cell preservation is achieved, but the complexity of administration routes increases
Solution Approach 1:
The patent applies segmentation by dividing the administration approach into multiple distinct routes (topical, systemic, intratympanic) that can be selected based on the specific sensory loss type. This allows the same neuroprotective peptide to be delivered through different pathways tailored to the target tissue, simplifying the overall therapeutic strategy while maintaining flexibility.
