Are centrioles really absent in human neurons?

Question

A booklet (issued by my school) claims, Centrioles, formerly believed to be absent in neurons, have been described in neurons and may be associated with the production and maintenance of neuro(micro)tubules in them.I was under the impression that mature human neurons are totally *devoid* of centrioles.Being something circulated at a school, it lacks niceties such as citations/references. I've done a spot of Googling, but that didn't yield anything confirming the claim in the booklet.------------Q- As per latest studies/info. do (mature) human neurons really possess centrioles?

Answer 1

I have spent some time researching your question and it may be possible that the pamphlet you are talking about is referencing neurons in development? Neurons grow and divide during early development and require centrioles at that time. Once the neuron matures it will stop expressing centriole genes.

If that is not the answer you are looking for, it looks like there is some "fairly new" research being done in C. elegans suggesting that centrioles play a role in their cillia production.
