Membrane Biology: Nothing can replace polyunsaturated lipids

Genetic studies reveal that polyunsaturated lipids do more than simply increase the fluidity of the cell membrane.

Thrilled to share this amazing work from Marie Blanchette & team in the Daneman Lab!!! We found that differences in the BBB across brain regions help regulate local brain function 🧠 Honored to have contributed to the study & to have had Marie as a mentor during my PhD💕

This is amazing.

And it's not just math talent: she is a mature communicator now.
She blossomed when moving from homeschooling to math communities in Chicago and at Berkeley.
This is a story that should inspire us.

We examine the growing evidence that vascular dysfunction plays a key role in cognitive decline in ageing and dementia, and argue that preserving/restoring CBF should be central to future therapies.

Metformin, the first line drug for Type 2 diabetes, has been used for 60 years without a clearcut mechanism of action. It turns out it's not just reducing glucose output from the liver. Metformin also works via the brain www.science.org/doi/10.1126/...

Low-dose metformin requires brain Rap1 for its antidiabetic action

Metformin lowers blood glucose by inhibiting Rap1 in ventromedial hypothalamic neurons that regulate glucose balance.
