Modulating Insect Ionotropic Receptors for Sensory Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective solutions for modulating hygrosensing and thermosensing in insects, particularly mosquito vectors, which are crucial for controlling disease transmission, as the genetic and molecular mechanisms underlying these sensory processes in insects remain poorly understood.
Innovation Solution
Administration of agents that modulate the activity or expression of specific ionotropic receptors (Ir25a, Ir93a, Ir40a, and Ir68a) in insects to disrupt their hygrosensing and thermosensing capabilities, using expression vectors with site-specific endonucleases and guide RNAs for targeted gene editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to control insect populations, then disease transmission can be reduced, but the genetic and molecular mechanisms underlying hygrosensing and thermosensing remain poorly understood
Solution Approach 1:
The patent segments the sensory system into specific ionotropic receptors (Ir25a, Ir93a, Ir40a, Ir68a) that can be individually targeted and studied. This segmentation allows researchers to understand specific molecular mechanisms while simultaneously developing targeted control methods for disease transmission
Solution Approach 2:
The patent uses small molecule compounds as intermediaries that selectively bind to and modulate specific ionotropic receptors. These compounds serve as tools to both probe sensory mechanisms and disrupt vector behavior, addressing both understanding and control needs
2Reliability
If insect vectors are controlled by disrupting their sensory capabilities, then survival and reproductive capability are reduced, but the complexity of identifying and targeting specific receptors increases
Solution Approach 1:
The patent employs partial action by targeting specific ionotropic receptors rather than attempting to disrupt all sensory pathways simultaneously. This selective approach reduces complexity while maintaining effective population control through disruption of critical sensory functions like hygrosensing and thermosensing
Solution Approach 2:
The patent changes the chemical parameters of small molecule compounds to achieve selective binding to specific ionotropic receptors. By adjusting molecular structure and properties, the system can target different receptors (Ir25a, Ir93a, Ir40a, Ir68a) with appropriate selectivity, managing complexity through systematic parameter optimization
3Ease of operation
If small molecule compounds are used to modulate ionotropic receptor activity, then hygrosensing and thermosensing are disrupted, but the specificity and selectivity of modulation must be precisely controlled
Solution Approach 1:
The patent applies local quality by designing small molecule compounds with specific structural features that confer selectivity for particular ionotropic receptors. Each compound is optimized with local molecular characteristics (functional groups, stereochemistry, binding pocket interactions) that enable precise targeting of specific receptors while sparing others, achieving both ease of operation and manufacturing precision

AI summary
A method of modulating hygrosensing and/or thermosensing in an animal, particularly, an insect or disease vector, is provided. Also provided is a method of reducing survival, host-seeking, and/or reproductive capability of an animal, particularly an insect or disease vector. The methods involve an effective amount of an agent that modulates the activity and/or expression of a polynucleotide or polypeptide of an ionotropic receptor (Ir) selected from one or more of Ir25a, Ir93a, Ir40a, Ir68a, or Ir21a. A method of identifying an agent that modulates survival, host-seeking, and/or reproductive capability of an animal, e.g., an insect, is further provided.
