The good mutation

Weizmann Institute of Science scientists have discovered a new pathway that may protect nerve cells in the brain and slow down the development of degenerative brain disease

Heavy weight pellets

Weizmann Institute of Science scientists deciphered the molecular mechanism of "return to normal" and discovered that it is based on labeling proteins for destruction with a special code known as "SUMO"

Coloring of the meeting areas between nerve cells (green) and muscle (red). The yellow staining represents complete overlap between the nerve cells and the muscle in normal mice (bottom). In transgenic mice, which lack microRNA in nerve cells that innervate muscles, only the muscle staining is visible (above, in red), because the nerve in the junction area is diseased.

ALS - suddenly in the middle of life

The motor neurons, which control voluntary muscle movement, gradually degenerate. As a result, the patient loses the function of most muscles
