Hello all! During mitosis the telomeres reduced. But neurons do not divide during postnatal period (neural stem cells are exclusion). So - does Hayflick limit exist for neurons?
Thanks
Thanks
Telomeres are repetitive DNA sequences found at the ends of chromosomes. They act as protective caps to prevent the loss of important genetic information during cell division. As we age, telomeres naturally become shorter and this has been linked to various age-related diseases.
Yes, telomeres have been found in neurons. However, they are shorter and less well-studied compared to telomeres in other cell types.
Yes, telomeres in neurons can become shorter with age. This is due to the limited ability of neurons to regenerate and the natural process of cell division.
Research has shown that stress, inflammation, and oxidative damage can accelerate the shortening of telomeres in neurons. Conversely, healthy lifestyle habits such as exercise and a balanced diet may help slow down the shortening process.
While there is no direct evidence, studies have shown a correlation between shorter telomeres in neurons and the development of neurodegenerative diseases such as Alzheimer's and Parkinson's. Further research is needed to fully understand the role of telomeres in these diseases.
