Unraveling the Impact of Protein Misfolding on Neurodegeneration
Protein misfolding and deposits in the brain are common factors in neurodegenerative diseases. Recent research explores the phenomenon of cross-seeding, where misfolded proteins from one disease can induce the aggregation of others. A study focused on the interaction between the prion protein and TDP-43 reveals how they collaborate to impact neurodegenerative diseases by triggering the clumping and inactivation of TDP-43. This new mechanism sheds light on how disease-associated prion proteins can affect physiological signaling pathways through cross-seeding.
