TWiN 30: Gut to brain spread of alpha-synuclein in Parkinson’s disease

TWiN describes experiments demonstrating that gut injection of alpha-synuclein fibrils in mice converts endogenous alpha-synuclein to a pathologic form that spreads to the brain and leads to features of Parkinson’s disease.

TWiN 23: Peripheral nervous system with Bruce Carter

Bruce Carter joins TWiN to discuss the peripheral nervous system: the development of nerves that convey sensory information like touch from the tips of your toes to the brain, and Schwann cells, which are necessary for ensuring that those sensory signals are sustained as they travel long distances to the brain.

Hosts: Vincent Racaniello, Timothy Cheung, and Vivianne Morrison
