Objective: Use mitochondria-targeted optogenetic actuators to precisely and reversibly control mitochondrial function and study downstream metabolism in disease-relevant models.

Why it works: The review frames light-activated mitochondrial channels and pumps as enabling direct, reversible perturbation of mitochondrial function, which helps move studies from association to causation.

Priority logic: The stated priority is to obtain precise and reversible control of mitochondrial function first, so downstream metabolic and disease-related consequences can be interpreted mechanistically.

Validation strategy: The review states that it summarizes results obtained with each tool and outlines best practices for using optogenetic approaches to control mitochondrial function and downstream metabolism.

Target properties: precision of control, reversibility, mitochondrial activity modulation, downstream metabolic response

Target mechanisms: light-activated cation conductance in mitochondria, light-activated proton pumping in mitochondria

Target techniques: optogenetic perturbation, mitochondrial targeting of genetically encoded actuators

Evidence Snippets

Here, we highlight emerging reagents-mitochondria-targeted light-activated cation channels or proton pumps-to decrease or increase mitochondrial activity upon light exposure, a technique we refer to as mitochondrial light switches, or mtSWITCH.

The mtSWITCH technique is broadly applicable because energy availability and metabolic signaling are conserved aspects of cellular function and health.

A prior lack of precise and reversible methods to control mitochondrial function limited causal analysis of mitochondrial contributions to disease-related metabolism.
