Abstract :
Given that neurons are post-mitotic cells, their life span is generally long enough to reach that of humans. However, sometimes neurons die without recognizable causes, as a result of a process called neurodegeneration. Apart from when gene mutations can be correlated with disease, it is difficult to pinpoint molecules that are responsible for neuronal death. Therefore, neurons living in a ‘sick state’ for many years might reveal important information about neuronal death. Systematic and extensive single-neuron analysis of ‘sick’ neurons is expected to provide clues to the mechanisms of neurodegeneration. Moreover, the elimination of putative triggering and promoting factors involved in neurodegenerative disease might prevent disease progression.
