Novel therapeutic interventions are being proposed for Parkinson’s on a regular basis, with compelling data supporting their future development.
The case is strengthened when a measure of target engagement is also involved – providing not only a potential therapy but also a biomarker as well.
Recently, a biotech company called AcureX Therapeutics has been presenting just such a case, based on a biological mechanism involving the protein Miro1.
In today’s post, we will discuss what Miro1 is and how it might be useful for future clinical trials.

Watching the recent Michael J Fox Foundation‘s Progress in the PD Pipeline webinar (Wednesday 10th November, 2021), I was really impressed by the presentation by Dr Bill Shrader (co-founder and CEO/CSO of AcureX Therapeutics)
In particular, I really liked their approach to potential patient selection for future clinical trials of their lead drug candidate. It all revolves around the analysis of Miro1 as a biomarker.
What is Miro1?

Stanford University researchers have recently published an interesting report in which they not only propose a novel biomarker for Parkinson’s, but also provide some compelling data for a novel therapeutic approach.
Their research focuses on a protein called Miro, which is involved in the removal of old or faulty mitochondria. Mitochondria are the power stations of each cells, providing cells with the energy they require to do what they do.
Specifically, the researchers found that Miro refuses to let go of mitochndria in people with Parkinson’s (which could act as a biomarker for the condition). They also found that pharmacologically forcing Miro to let go, resulted in neuroprotective benefits in models of Parkinson’s
In today’s post, we will discuss what Miro is, what the results of the new research suggest, and we will consider what will happen next.
Every now and then a research report comes along and you think: “Whoa, that’s amazing!”
It a piece of work that breaks down your cynicism (which you have proudly built up over years of failed experiments) and disciplined scepticism (a critical ingredient for a career in scientific research – mantra: ‘question everything’). And for a moment you are taken in by the remarkable beauty of not just good research, but biology itself.
A couple of weeks ago, one such research report was published.
This is it here:
Title: Miro1 Marks Parkinson’s Disease Subset and Miro1 Reducer Rescues Neuron Loss in Parkinson’s Models.
Authors: Hsieh CH, Li L, Vanhauwaert R, Nguyen KT, Davis MD, Bu G, Wszolek ZK, Wang X.
Journal: Cell Metab. 2019 Sep 23. [Epub ahead of print]
It’s a really interesting study for several reasons.
So what did they report?
