Genetic variations in a region of our DNA called PARKIN is associated with an increased risk of developing Parkinson’s – particularly young-onset PD (diagnosed before the age of 40yrs).
This area of DNA provides the instructions for making a protein (also referred to as PARKIN), which plays a number of important roles inside of cells.
Recently, a South Korean biotech company called Cellivery has published research on an experimental therapeutic agent that easily penetrates both the brain and cells within, delivering PARKIN protein to the cells that need it.
In today’s post, we will discuss what PARKIN does, review the new research report, and explore what could happen next.
Here on the SoPD we often talk about research regarding the prominent Parkinson’s associated proteins, think of alpha synuclein, LRRK2 and GBA. And they are of interest as there is a great deal of activity now at the clinical level exploring agents targetting these proteins.
But there are a number of interesting therapeutics being developed that are exploring some of the other Parkinson’s-associated proteins.
A good example was published this week:
Title: Intracellular delivery of Parkin rescues neurons from accumulation of damaged mitochondria and pathological α-synuclein
Authors: Chung E, Choi Y, Park J, Nah W, Park J, Jung Y, Lee J, Lee H, Park S, Hwang S, Kim S, Lee J, Min D, Jo J, Kang S, Jung M, Lee PH, Ruley HE & Jo D
Journal: Science Advances, 29 Apr 2020:6, 18, eaba1193
In this study, South Korean researchers demonstrated that a brain penetrating compound (including the PARKIN protein) can rescue numerous models of Parkinson’s.
Hang on a second: What is PARKIN?
