Greg Redpath

I am a cell biologist focussing on receptor movement in the cell and how this regulates receptor signalling, with a specific interest in serotonin signalling. My work typically uses live cell imaging, coupling confocal, TIRF and super-resolution microscopy with signalling biosensors to visualise receptor trafficking and signalling responses in real time.

Highlighting signalling biosensors 1.

Posted by Greg Redpath, on 16 January 2025

Why there is interest in signalling biosensors, considerations for using biosensors, and the original biosensor, GFP. Why write about signalling biosensors? In my first postdoctoral position, I was introduced to the concept of endosomal signalling- a way for receptor signalling outcomes to be changed by delivering a signal to different regions of the cell. I

Meeting report: Biomolecular Horizons 2024

Posted by Greg Redpath, on 6 January 2025

In September 2024 I attended the Biomolecular Horizons conference in Melbourne, Australia. This was a large conference with 9 concurrent sessions over 4 days. There was a lot of great biology presented from around the world, but in my meeting report I wanted to highlight something unique about the conference: the Indigenous Perspectives in Biomolecular

An interview with Dr. Vaishnavi Ananthanarayanan
