At the end of each month the SoPD writes a post which provides an overview of some of the major pieces of Parkinson’s-related research that were made available during July 2022.
The post is divided into 10 parts based on the type of research:

So, what happened during July 2022?
In world news:
July 8th – Former Prime Minister of Japan Shinzo Abe was assassinated while giving a public speech in the city of Nara, Japan.
July 11th – The first operational image (Webb’s First Deep Field) from the technologically amazing James Webb Space Telescope was presented to the public. The image revealed the galaxy cluster SMACS 0723 – a cluster of galaxies about 4 billion light years from Earth (everything about this project excites me – especially Trappist 1):
July 28 – The Commonwealth Games began in Birmingham, England.
July 28th – DeepMind announced that their AlphaFold tool has determined the structures of almost every protein (around 200 million proteins) – just one year after releasing data on the first 20,000 proteins. The freely available 23-terabyte database represents “the beginning of a new era of digital biology” – click here to read more about this)
July 30th – Billionaire Bill Gates increased his commitment to Alzheimer’s research (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 July 2022, there were 894 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (7,103 for all of 2022 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).
The top 5 pieces of Parkinson’s news
1. Is alpha synuclein ‘interferon’ with the immune response?:
Researchers reported that Parkinson’s-associated α-synuclein is required for neuronal expression of interferon-stimulated genes (in response to viral infection). Curiously, when neurons that do not have α-synuclein are treated with type 1 interferon, they failed to induce a broad range of interferon stimulated genes, suggesting that α-synuclein interacts with type 1 interferon signaling. In addition, interferon-mediated phosphorylation of STAT2 is also dependent on α-synuclein. The researchers also looked at postmortem brain tissue from people with Parkinson’s (Click here to read more about this & click here to read an OPEN ACCESS version of the report).
2. Treadmills, PPARα, and fenofibrate:
Researcher reported that treadmill exercise reduced the spread of α-synuclein aggregation pathology in aged genetically engineered (A53T) mice. They determined that this effect resulted from the activation of Peroxisome proliferator-activated receptor alpha (PPAR-α) which stimulated lysosomal biogenesis (via TFEB). Interestingly when the researchers treated mice with fenofibrate – a PPARα agonist – in the absence of exercise, it also reduced α-synuclein aggregation pathology (Click here to read more about this).
3. Does Yerbe mate matter?
A multicenter case-control study across 3 countries (Argentina, Paraguay, & Uruguay) found an association between Yerba mate tea concentration per serving and lower risk of developing Parkinson’s (Click here to read more about this and click here to read a SoPD post on the topic).
4. Astrocytes to the rescue:
Researchers reported that astrocytes can alleviate Parkinson’s-related α-synuclein pathology by regulating a series of the proteostasis procedures (involving formation, transmission, disaggregation, & clearance of aggregates) both in vitro & in vivo. In addition, transplantation of healthy midbrain astrocytes into a Parkinson’s mouse model reduced α-synuclein pathology and protected the dopamine neurons from neurodegeneration (Click here to read more about this and click here for the associated editorial).
5. PD-associated protein affects communication within cells:
Disturbed contacts between intracellular structures like the endoplasmic reticulum & mitochondria is affected in some cases of Parkinson’s. Now researchers have reported that a protein called “cysteine-rich with EGF-like domain (Creld)” regulates ER-mitochondria communication. Creld is “a poorly characterized risk gene for PD”, but loss of this protein led to mitochondrial hyperfusion and reduced oxidation in various models (Click here to read more about this).
