[Prion-Like Spreading](/entities/prion-like-spreading) Neurons are neurons capable of transmitting pathological protein aggregates through mechanisms resembling prion propagation. This phenomenon involves the templated misfolding and cell-to-cell transfer of disease-associated proteins, enabling the spread of neurodegeneration throughout connected neural circuits.

Overview
The concept of prion-like propagation in neurodegeneration emerged from observations that pathological protein aggregates can: [@frost2010]
Transfer between connected neurons
Template the misfolding of endogenous proteins
Propagate along neural networks
Cause progressive, stereotypic disease progression
[Unfolded protein response](/entities/unfolded-protein-response)
Autophagy-lysosomal degradation
Proteasomal clearance
Innate immune response
