TWiN 14: Reducing Alzheimer-like pathology in mice Jan 14, 2021

Show notes

Ori, Jason, and Vincent discuss the use of antibodies to neutralize amyloid-β seeds before their deposition becomes detectable in transgenic mice, and the finding that the preclinical phase of Alzheimer's disease may be a late manifestation of earlier pathogenic seed formation.

TWiN 12: A gene for short-term memory Nov 11, 2020

Show notes

Ori, Jason, and Vincent reveal identification of an orphan receptor that modifies short-term memory in mice, and a mouse model of COVID-19 that includes anosmia or loss of smell.

TWiN 10: Remodeling synapses with a cytokine Sep 29, 2020

Show notes

TWiN explains how a cytokine produced by neurons activates microglia which modify the extracellular matrix and remodel synapses, leading to memory consolidation.
