Excited to share this recent preprint from the @MickLab. They cleverly join APEX-proximity biotinylation, which usually requires exogenous addition of H2O2, with D-aminacid-induced local H2O2 production by expression of the yeast DAO. It's genious!

[HarbauerLab @HarbauerL]

Molecularly, the Pink1 mRNA tethering complex is phosphorylated by #AMPK to keep the amount of PINK1-mediated mitophagy low. Only upon untethering, e.g. upon inactivation of AMPK by insulin signaling, can mitophagy process and the neuron take care of damaged mitochondria.

[HarbauerLab @HarbauerL]

This goes awry in neurons that have lost their ability to respond to insulin, e.g. upon treatment with the #Alzheimers disease (AD) risk factor ApoE4. This connects two phenomena commonly seen in AD, damaged mitochondria and #insulin resistance.

[HarbauerLab @HarbauerL]

Tabitha identified a molecular switch that allows neurons to turn #mitophagy on and off, by tethering the Pink1 mRNA to mitochondria. This protects #mitochondria in neurons from being used as a simple nutrient source, because we all know they are much more important than that!

[HarbauerLab @HarbauerL]

Could not be more proud to share the story one of my first PhD students in the lab. Shout out to Tabitha!

In a new study, @HarbauerL found that insulin supports the recycling of dysfunctional mitochondria in neurons. Energy scarcity or interrupted insulin signals can lead to the continued use of defective mitochondria, which might affect neurodegenerative diseases. Read more: https://t.co/6qrmyb1msc
