IBD+TNF AB ≠ PD?

The cryptic title of this post will hopefully make sense by the time you have finished reading the material present here.

This week, new research from the USA points towards an increased risk of Parkinson’s (PD) for people that suffer from inflammatory bowel disease (IBD). 

That same research, however, also points towards a clinically available treatment that appears to reduce the risk of Parkinson’s in individuals affected by inflammatory bowel disease. That treatment being: anti–tumor necrosis factor antibodies (TNF AB). Is that title making sense yet? If not, read on.

In today’s post, we will outline what inflammatory bowel disease is, review what the new research found, and discuss what is known about TNF in Parkinson’s.

Inflammatory bowel disease (or IBD) is one of these umbrella terms that is used to refer to a group of inflammatory conditions of the large and small intestine:

The symptoms of IBD can include abdominal pain, diarrhoea, vomiting, rectal bleeding, severe internal cramps/muscle spasms in the region of the pelvis, and weight loss.

The most common forms of IBD are Crohn’s disease and ulcerative colitis.

There has been an increased incidence of IBD since World War II, which could be associated with increased awareness and reporting of the condition, but it could also be linked with increases in meat consumption (Click here to read more about this). For example, in 2015, an estimated 1.3% of U.S. adults (3 million) were diagnosed with IBD, which was a large increase on the levels in 1999 (0.9% or 2 million adults – Source: CDC).

This is delightful, but what does it have to do with Parkinson’s?

So this week, an interesting study was published on the Journal of the American Medical Association – Neurology edition website:

Happy birthday: Silverstein Foundation

Over the last 12 months, the Silverstein Foundation has quickly established itself as a major focused force in the fight against Parkinson’s.

And when I say ‘focused’, I mean ‘focused’ –  the foundation is “actively pursues and invests in cutting edge research with the goal of discovering new therapies for the treatment of Parkinson’s Disease in glucocerebrosidase (GBA) mutation carriers”.

But the output of this effort may well have major benefits for the entire Parkinson’s community.

In today’s post, we will discuss what GBA is, how it functions inside cells, its association with Parkinson’s, and what all of this GBA focused research being funded by the Silverstein Foundation could mean for the Parkinson’s community.

This is Jonathan Silverstein.

He’s a dude.

He is also a General Partner and a Co-Head of Global Private Equity at OrbiMed – the world’s largest fully dedicated healthcare fund manager. During his time at OrbiMed, the company has invested in healthcare companies that have been involved with over 60 FDA approved products.

In February 2017, he was diagnosed with Parkinson’s disease at just 49 years of age.

Rather than simply accepting this diagnosis, however, Mr Silverstein decided to apply the skills that he has built over a long and successful career in funding biotech technology, and in March 2017, he and his wife, Natalie, set up the Silverstein Foundation.

They raised $6 million from donors and then provided another $10 million of their own money to fund the endeavour, which has funded a dozen research projects and started a new company called Prevail Therapeutics (we’ll come back to this shortly).

The foundation has just one mission: “to actively pursue and invest in cutting edge research with the goal of discovering new therapies for the treatment of Parkinson’s Disease in GBA mutation carriers”

And it seeks to address this by achieving three goals:

  1. to find a way to halt the progression of Parkinson’s with GBA.
  2. to identify regenerative approaches to replace the damaged/lost cells
  3. to find preventative measures

What is ‘GBA’?
