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.

Telomeres and diseases (1)

The review examines the mechanisms of the development of diseases associated with telomere defects, the potential role of telomere elongation in the treatment of diseases, as well as in preventing the start of the aging process or its reversal.

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.

A shaggy Siberian digger?

According to preliminary data, the common sleeper can become a Russian alternative to the famous naked digger: he lives much longer than rodents of the same size (how much is still unknown) and, it seems, does not age until death.
