In search of vegetable preparations for nervous system diseases prophylaxis and treatment Russian researchers have turned to green tea. Specialists of the Kuban State University, the Kuban Research-and-Production Laboratory of Physiologically Active Substances and the Institute of Brain (Russian Academy of Medical Sciences) have discovered that ethanolic extract of green tea stimulates spinal cord neurons’ regeneration.
Spinal ganglia were cultivated in nutrient medium. Dry extract in different concentrations was added to the medium. The researchers judged on neurons state and their capacity for regeneration by the number and length of nerve cell processes. The length and number of processes account for the ‘quality of communication’ between neurons and ultimately the ability of the nervous system section to fulfill its functions. The ability to restore bonds is the rate of cells’ resistance to neurodegenerative diseases, for example, ischemia or Parkinsons disease.
The green tea extract had the most apparent stimulatory action in concentration of 0.004-0.006 percent. On the second day of cultivation, the number of cell processes started to grow as compared to the background ones, and then the length of cell processes began to increase. On the fourth day of experiment, the difference between the background and experimental groups was maximum both in terms of processes number and length. On the fifth day, the green tea extract effect disappeared.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
