Telomeres and diseases (4)

Simple but attractive arguments concerning the relationship between telomere length and aging should today be viewed with a certain degree of skepticism as contradictory, simplistic and potentially dangerous.

Telomeres and diseases (2)

The classic "telomere disease" is congenital dyskeratosis, a rare hereditary disease characterized by defective bone marrow function. Most adult telomeropathies are the result of mutations that are more likely to be risk factors.

Another mechanism of neuronal death in Alzheimer's disease

Astrocytes, which provide neurons with nutrition and oxygen, become the unwitting culprits of their death, since high levels of amyloid peptides induce their apoptosis. Deprived of nutrition, neurons degenerate.
