Abstract
Colchicine is an anti-inflammatory drug. It is a naturally occurring alkaloid derived from the Autumn Crocus plant, and
has a long history of therapeutic use in treating gout, familial Mediterranean fever, and pericarditis. Its primary
mechanism of action involves disrupting tubulin, which in turn modulates multiple inflammatory pathways. This
disruption reduces neutrophil activity and migration across the vascular endothelium. The colchicine-induced
neurodegeneration model is used to study Alzheimer’s disease (AD) because it mimics its key symptoms, including
memory loss and damage to cholinergic neurons. This type of model helps in understanding the disease and in developing
potential treatments. In AD patients, neurodegeneration is not limited to one area of the brain. Other brain areas, such
as the corpus striatum and parietal cortex, exhibit amyloid plaques, and the amygdala undergoes atrophy, as observed in
the MRI studies. This review aims to provide a comprehensive overview of the current state of knowledge on colchicine
induced neurodegeneration in the brain. We discuss the mechanisms underlying colchicine's neurotoxic effects, including
its disruption of microtubule dynamics, inhibition of the NLRP3 inflammasome (part of the innate immune system), and
induction of oxidative stress. We also explore the evidence for colchicine-induced neurodegeneration in various animal
models, including rats and fishes, and discuss the implications for human health.
