So, what happened during December 2024?
In world news:
December 8th – The President of Syria, Bashar al-Assad, fled Damascus after being overthrown, ending his presidency and the Ba’athist Syria regime after a total of 61 years. The Syrian opposition forms the Syrian Transitional Government as a provisional government.
December 11th – FIFA announces that Argentina, Paraguay and Uruguay will jointly host the 2030 Football World Cup (while Saudi Arabia is confirmed as the host for 2034).
December 12th – Indian chess prodigy Gukesh Dommaraju defeats former world champion Ding Liren in the 2024 World Chess Championship, breaking the previous age record of 22 set by Garry Kasparov by becoming champion at 18 years, 195 days old.
December 13th – A new light-induced gene therapy using nanoparticles to target the mitochondria of cancer cells is demonstrated (Click here to read more about this).
December 24th – The Parker Solar Probe flew to within 3.8 million miles (6.1 million kilometers) of the surface of the sun – this placed it within the sun’s corona, or atmosphere. It was also believed to be traveling at 430,000 mph (692,000 kph) during its passage of the corona – a new record for fastest man-made object (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 December 2024, there were 1,085 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (12,132 for all of 2024 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 6 pieces of Parkinson’s news
1. Prasinezumab continues with new results from PADOVA:
The pharmaceutical company Roche announced that their Phase IIb PADOVA study of the alpha synuclein targeting antibody Prasinezumab just missed its primary endpoint (p=0.0657), but their data suggests possible clinical benefit in early-stage Parkinson’s. This was an 18 month investigation in 586 people with early-stage Parkinson’s (on stable symptomatic treatment). The treatment continued to be well tolerated, with no new safety signals. Positive trends seen across secondary & exploratory endpoints were observed (Click here to read more about this).
2. Functional analysis of the African GBA1 variant:
Researchers (supported by ASAP) published a new paper that reported the functional effect of the African ancestry-specific GBA1 non-coding Parkinsons risk variant that was discovered last year. They discovered that it interferes with splicing of functional GBA1 transcripts and this results in less GCase protein & reduced GCase enzymatic activity (Click here to read more about this).
3. When the Orchestra goes quiet:
The pharmaceutical company UCB (and partner Novartis) announced the results of the proof-of-concept study ORCHESTRA study investigating the efficacy of the small molecule alpha synuclein aggregation inhibitor minzasolmin. They reported that the agent had not reached its primary or secondary endpoints (pre-determined measures of efficacy) in the 18 month study involving 496 patients with early-stage Parkinson’s (Click here to read more about this).
4. New biomarker for LRRK2 Parkinson’s:

New research reports that the ketone body β-hydroxybutyrate regulates protein solubility & is selective for a misfolding structural state. Effects observed in vitro, ex vivo, & in vivo (Click here to read more about this and click here to read a press summary associated with this research).
6. Peering inside of lysosomes:
Lysosomes are a crucial part of the waste disposal system of cells, and they have been implicated in some forms of Parkinson’s. Researchers presented a new method – called ‘tagless LysoIP’ – that enables enrichment of lysosomes (using TMEM192) directly from clinical samples & human cell lines. They researchers demonstrated that power of this new technique by reporting that metabolic profiling shows accumulation of glycerophosphodiesters in CLN3 disease patients (this an inherited disorder that primarily affects the nervous system – Click here to read more about this).
