Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
GFP-PHR-caspase8/Flag-CIB1N-caspase8 is a blue light-responsive two-component optogenetic caspase-8 system composed of GFP-PHR-caspase8 and Flag-CIB1N-caspase8 fusion proteins. Under blue light, the two components interact more strongly and undergo light-dependent cleavage, consistent with inducible caspase-8 activation.
Usefulness & Problems
Why this is useful
This system provides optical control over caspase-8-associated cell death signaling using a genetically encoded two-component switch. Reported use cases include stronger apoptosis induction in the Opto-Casp8-V2 configuration and regulation of inflammasome activation and pyroptosis under conditions where apoptosis and necroptosis are compromised.
Source:
Our optogenetic tool enables precise modulation of Caspase-8 activity, inducing cellular apoptosis.
Source:
In this study, we developed an optogenetic approach to rapidly modulate the activation of caspase-8 in response to blue light.
Problem solved
It addresses the need for temporally controlled activation of caspase-8-dependent death pathways with light rather than constitutive or chemically induced activation. The available evidence specifically supports blue light-dependent interaction and cleavage of the fused caspase-8 components.
Problem links
Need conditional recombination or state switching
DerivedGFP-PHR-caspase8/Flag-CIB1N-caspase8 is a blue light-responsive two-component optogenetic caspase-8 system built from PHR and CIB1N fusions. Under blue light, the fusion proteins show increased interaction and light-dependent cleavage, with associated accumulation of activated caspase-8 and caspase-3.
Need precise spatiotemporal control with light input

The construct architecture consists of GFP-PHR fused to caspase-8 and Flag-CIB1N fused to caspase-8, indicating a domain-fusion, two-component design. Blue light is the activating input, and co-immunoprecipitation was used to assess light-enhanced interaction; no additional practical details such as expression system, chromophore requirements, or delivery method are specified in the supplied evidence.
The evidence provided is limited to a single 2023 Research Square source and a small number of reported observations. Quantitative performance metrics, illumination parameters, cell-type scope, reversibility, background activity in the dark, and independent replication are not provided in the supplied evidence.

Under blue light control, the tool regulates inflammasome activation and induces pyroptosis when apoptosis and necroptosis mechanisms are compromised.
Additionally, through blue light control, it regulates the activation of the inflammasome and induction of pyroptosis in cases where apoptosis and necroptosis mechanisms are compromised.

Blue light exposure decreased precursor PHR-Caspase8 abundance and increased activated caspase-8 (P18) and caspase-3 accumulation.
After exposure to blue light, the abundance of the precursor protein PHR-Caspase8 decreased, while the activated forms of caspase8 (P18) and caspase3 accumulated.

Comparisons
Source-backed strengths
The source reports blue light-dependent cleavage of both GFP-PHR-caspase8 and Flag-CIB1N-caspase8 together with stronger interaction in co-immunoprecipitation assays. Comparative evidence further states that Opto-Casp8-V2 showed more efficient self-cleavage and consumption than Opto-Casp8-V1 under blue light and promoted apoptosis more strongly.
