Summary

optoRET is an optogenetic RET signaling switch created by fusing the cytosolic region of human RET to a blue-light-inducible homo-oligomerizing protein. Blue-light stimulation modulates RET pathway output, including Grb2 recruitment and activation of AKT and ERK, and can also induce local filopodia-like F-actin structures through Cdc42 activation.

Usefulness & Problems

Why this is useful

optoRET enables light-dependent control of RET signaling with temporal precision, as varying photoactivation duration was reported to dynamically modulate pathway output. It was also used to modulate RET signaling in dopaminergic neurons of the mouse substantia nigra, indicating utility for probing signaling function in neuronal contexts and in vivo.

Source:

Importantly, we successfully modulated RET signaling in dopaminergic neurons of the substantia nigra in the mouse brain.

Source:

Collectively, optoRET has the potential to be developed as a future therapeutic intervention, modulating RET downstream signaling with light.

Source:

In the current study, we developed an optogenetic tool for modulating RET signaling, termed optoRET

Problem solved

optoRET addresses the problem of controlling RET signaling with spatiotemporal precision rather than relying on static or diffusible inputs. The reported local induction of filopodia-like F-actin structures at stimulated regions indicates that it can be used to dissect localized RET-dependent morphological responses.

Input: Light

Implementation Constraints

The reported design combines the cytosolic region of human RET with a blue-light-inducible homo-oligomerizing protein, so implementation requires expression of this fusion construct and blue-light illumination. The available evidence supports use in cultured neurons and in dopaminergic neurons of the mouse substantia nigra, but does not provide further details on delivery method, promoter choice, or cofactor requirements.

The supplied evidence is limited to a single 2023 study and a brief construct description, so quantitative performance metrics, reversibility, background activity, and spectral constraints are not established here. The identity of the blue-light-inducible homo-oligomerizing module and detailed construct architecture are also not provided in the supplied evidence.
