Could a New Target Unlock Parkinson’s Treatment?

(Summary Box)

Key Takeaway: Scientists have identified a potential new target for Parkinson’s disease treatment – a gene called FAM171A2. This gene appears to play a crucial role in how toxic proteins spread within the brain, contributing to Parkinson’s progression.

But wait, there’s more! This isn’t just another gene in a haystack. Researchers found a drug that blocks FAM171A2’s troublesome activity, offering a potential new avenue for therapy. Keep reading to discover how this exciting discovery could change the game for Parkinson’s.

A New Suspect in Parkinson’s Disease: Meet FAM171A2

Parkinson’s disease is a complex neurological disorder that affects movement. A hallmark of the disease is the buildup of misfolded proteins called alpha-synuclein (α-syn), which clump together to form toxic fibrils. These fibrils spread through the brain, leading to neuronal damage and dysfunction. But how exactly do these fibrils spread from neuron to neuron? A recent study may have finally cracked part of the code, and the prime suspect is FAM171A2.

The Sticky Situation with Alpha-Synuclein

Imagine α-syn fibrils as tiny, sticky burrs. They need a way to attach to and enter brain cells (neurons). This new research, published in PubMed, suggests that FAM171A2 acts as a sort of “welcome mat” for these sticky fibrils, making it easier for them to get inside neurons and cause trouble.

• Overexpression of FAM171A2: When researchers increased the amount of FAM171A2, the uptake of α-syn fibrils by neurons increased, worsening the toxic effects.
• Knockdown of FAM171A2: When researchers decreased FAM171A2, it had a protective effect, suggesting it’s a key player in the spread of the disease.

Electrostatic Attraction: Opposites Attract (Unfortunately)

The researchers discovered that a specific part of FAM171A2 (the extracellular domain 1) interacts with the tail end of α-syn (the C terminus) through electrostatic forces. Think of it like magnets – opposite charges attract. And in this case, the attraction is very strong, with FAM171A2 showing over 1000 times more selectivity for fibrils compared to other forms of alpha-synuclein.

A Potential Blockbuster Drug?

The best part? The researchers identified a drug called bemcentinib that blocks the interaction between FAM171A2 and α-syn fibrils. They tested this in cells and even in mice, with promising results!

Real-World Implications: A Glimmer of Hope?

This research is still in its early stages, mostly conducted in cellular and animal models. It’s important to remember that what works in mice doesn’t always translate to humans. However, this study offers a potential new therapeutic target for Parkinson’s disease. If bemcentinib or similar drugs prove effective in humans, it could lead to new treatments that slow or even prevent the progression of the disease.

Limitations and Future Directions

While exciting, the study has limitations:

• Animal Models: The research was primarily in mice. Human trials are needed.
• Specificity of Bemcentinib: Further research is needed to confirm bemcentinib’s safety and efficacy in humans and to determine if it has any off-target effects.
