Computer model reveals effect of increased cholesterol on specific ion channel in heart

Researchers used a computer model to study the effect of increased cholesterol on a specific ion channel involved in regulating potassium levels in the heart. They found that increasing cholesterol levels made interactions with the channel more numerous, overwhelming it and interfering with its ability to open and close normally.

Tau-tolly microtubular!

Researchers have created a near-atomic-resolution model of tau-microtubule interactions, revealing how tau stabilizes microtubules and forms aggregates that contribute to neurodegenerative diseases. The study provides insight into the mechanisms underlying tauopathies, such as Alzheimer's disease.

Our vulnerable nervous system: What affects its protective sheaths?

A team of scientists at FAU has discovered how protein molecules regulate the formation of myelin sheaths in the nervous system. The study found that Nfat proteins are essential for successful interaction between other protein molecules, and their inhibition can lead to myelin loss and neurological disorders like multiple sclerosis.
