Anti-cancer virus hitchhiking

Hiding "on the back" of red blood cells, the virus is not destroyed by the immune system, affects only cancer cells and stimulates an immune attack on infected and uninfected tumor cells and metastases.

Genomics: a time of great expectations

Enthusiasts of individual genomics promise a lot of opportunities to predict the risks of developing diseases and treatment features. But they are silent about the fact that this connection itself is not proven at all for many diseases.

Prolonging youth

It was possible to age the mice. Will it be possible to rejuvenate?

Scientists have discovered a signaling pathway, the inclusion of which aged the muscles of young rodents. The authors believe that their discovery will help develop drugs that suppress the activity of this system.
