# # # # Mitochondria are tiny structures inside of cells that function as power stations, providing cells with energy to conduct all of their functions. When mitochondria become dysfunctional, they can put a lot of stress on cells, potentially leading to cellular death. A common feature of Parkinson’s is mitochondrial dysfunction. Evolution has provided various methods of removing dysfunctional mitochondria. One of these processes is called mitophagy. One biotech company leading the charge in the field of enhancing mitophagy is Mission Therapeutics, and they have very recently published some interesting pre-clinical data on their lead clinical candidate. In today’s post, we will look at what mitophagy is, how Mission Therapeutics is attempting to enhance it, and what their newly published data reports. # # # #

Prof Sir Steve Jackson is a bit of a legend in research circles at the University of Cambridge.

In 1997, he founded a biotech called KuDOS Pharmaceuticals which developed a successful PARP1 inhibitor (Olaparib) for cancer. That company was acquired in 2005 by AstraZeneca who jointly (with Merck) owns and developed Olaparib (also known as Lynparza – and it may be of interest to readers that PARP1 inhibitors are now being considered for Parkinson’s – click here to read a previous SoPD post on this topic).

Not to sit on his laurels, Sir Steve then founded another biotech firm in 2011, called Mission Therapeutics. This company was focused on agents targeting deubiquitinating (DUB) enzymes (more on them in a moment).

In November 2018, the large pharmaceutical company AbbVie made some waves by signing a drug discovery and development deal with the 7-year old Mission Therapeutics, to explore deubiquitylating enzymes (or DUBs) in the context of Alzheimer’s and Parkinson’s (Source).

And then in August of 2021, the companies signed another deal (Source), which involved AbbVie announcing progression of two selected DUB targets into the next phase of research.

Very recently, Mission Therapeutics has published research on its own research into Parkinson’s and the results are VERY interesting.

What did they find?

# # # # While disease modifying therapies are the ultimate goal for better treating Parkinson’s, research into therapeutic approaches that can provide better quality of life of people living with the condition are equally important. Neuroprosthetics are devices that use electrodes to interface with the nervous system and aim to restore function that has been lost. Cochlear implants are a good example of a neuroprosthetic that is improving people’s hearing. Recently, researchers in Switzerland have presented initial findings for a spinal cord neuroprosthesis that can help alleviate the locomotor deficits experienced in Parkinson’s. In today’s post, we will review the recent research and discuss what it could mean for the future of Parkinson’s treatment. # # # #

The “Cairo toe”. Source: Smithsonianmag

The experts will tell you that the “Cairo toe” is special because it is flexible.

That is to say, it physically bends.

And this ‘bending’ property makes it rather unique among ancient prosthetics.

You see, when it was constructed (between 2,700 and 3,000 years ago), most artificial limbs were only cosmetic, rather than functional. And this difference is made particularly clear when one compares the “Cairo toe” with other early prosthetics of the same age that do not bend (Source):

An unwillingness to bend. Source: britishmuseum

So for its time, the “Cairo toe” must have been positively state of the art technology. It was one of the first functional prosthetics.

Great, but what does this have to do with Parkinson’s???

Well, we have come a long way since the “Cairo toe” with prosthetics, and recently researchers have been exploring a new kind of functional prosthetic – an implant – with the goal of improving quality of life for people with Parkinson’s.

What do you mean?

# # # # In October 2018, the author of this blog left academia and joined the medical research charity “Cure Parkinson’s“. It was a tiny organisation focused on disease modification in Parkinson’s, and I was really excited by the opportunity. Cure Parkinson’s is widely seen as punching well above its weight in terms of impact (there were only 18 members of staff when I joined) and relentless in their efforts to bring novel therapies forward for the Parkinson’s community. I was flattered by the invitation to join the team. The last 5 years has been one of the busiest and most stimulating periods of my life. And I have absolutely no regrets with the decision I made. In today’s post, I will provide some observations and learnings from my experience over the last 5 years and discuss how the field of Parkinson’s research has changed. # # # #

Doesn’t time fly.

I was surprised recently when I received an email alert from LinkedIn. I very rarely use the service, but the message informed me that I have been with my current employer for five years now.

I scratched my head and thought, ‘no, that’s not possible‘.

But actually, yes it’s very possible (that whole COVID-related period of time really warped reality didn’t it?).

In October 2018, I finished up my post-doctoral research position at the University of Cambridge and joined the medical research charity Cure Parkinson’s as their deputy director of research.

The decision began in 2017 when I met Dr Richard Wyse, the director of research at the charity.

So, what happened during October 2023?

In world news:

October 3rd – Katalin Karikó and Drew Weissman shared the Nobel Prize in Physiology or Medicine for their work in developing mRNA vaccines, which played a crucial role in the COVID-19 pandemic.

 

October 3rd – The trial of Sam Bankman-Fried, founder of the cryptocurrency exchange company FTX, began. He faces seven charges of fraud and conspiracy.

 

October 7th – Hamas launched an incursion into southern Israel from the Gaza Strip, prompting a military response from the Israel Defense Forces – leading to the start of the Israel–Hamas war (click here to read more about this).

 

October 23rd – A significant breakthrough in treating cervical cancer was reported, with participants in a Phase III trial seeing a 35% reduction in the risk of both mortality or the disease returning. The study used a combination of existing, cheap drugs ahead of usual radiotherapy treatment (Click here to read more about this).

 

October 31st – Researchers released an AI system, called SIDE, to improve source-quality and reliability of Wikipedia by identifying problematic citations and recommending better ones to editors. They demonstrated potential AI applications in science such as for research suggestion tools and keeping track of accelerating scientific output (Click here to read more about this).

 

In the world of Parkinson’s research, a great deal of new research and news was reported:

In October 2023, there were 752 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (9,011 for all of 2023 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).

June 14th – Scientists have created synthetic human embryos using stem cells, in a advance that sidesteps the need for eggs or sperm – more “look-what-I-can-do” rather than “groundbreaking”. Certainly outpacing laws… maybe Charlotte can help (Click here to read more about this).
