Degenerative Uptake: Neuronal Toxin Accumulation in Neurodegeneration

Degenerative uptake is the process where neurons internalize and accumulate toxic substances (environmental toxins, misfolded proteins, metabolic byproducts), leading to dysfunction and death. Contributing factors: aging, genetic mutations, oxidative stress.

Implicated in Alzheimer's (amyloid-β, tau), Parkinson's (α-synuclein), Huntington's (mutant huntingtin). Blocking uptake or enhancing clearance is a therapeutic target.
