Chandelier Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [1]
Chandelier neurons, also known as axo-axonic cells, are a distinctive type of GABAergic interneuron that selectively innervate the axon initial segment (AIS) of pyramidal neurons. Their terminals form distinctive "candle-holder" arrays that terminate exclusively on AIS sodium channels (Somogyi et al., 1982). This precise targeting allows chandelier neurons to exert powerful control over pyramidal neuron output by regulating action potential initiation. In neurodegenerative diseases including Alzheimer's disease and epilepsy, chandelier neuron dysfunction contributes to network hyperexcitability and cognitive deficits. [2]
