Doctors offer to treat Alzheimer's disease by laser

Unfortunately, despite the relatively strong progress in the field of medicine, and treatment, are still disease, cope with that humanity can not. Yet this does not mean that we should not look for medicines. And not so long ago a group of doctors from Japan through the study of Alzheimer's disease, for the treatment of this disease offered the use of a laser that will actually "burn" boleznyu damaged areas in the brain.

What causes Alzheimer's disease

According modernized concepts, one of the causes of the disease may be a process of protein deposits called "amyloid" (or rather, its subspecies "beta-amyloid") in the brain. Proteins can "stick together" in groups, forming the so-called amyloid plaques. The result is the disruption of cell function and degeneration of the central nervous system cells and, as a consequence, inhibition of cognitive functions (i.e., memory, thought, and so on).

This is interesting: "Cocktail" of young blood to help stop the development of Alzheimer's disease.

But the artificial amyloid proteins are widely used, which is called "in vitro". For example, as a scaffold for growing cells or tissues. This often after growing frame becomes unnecessary. This means that it must somehow be destroyed without damaging the formed tissue. And such technology scientists have. Therefore, the Japanese seemed logical to adapt the technology to treat disease.

How to cure Alzheimer's disease

A group of researchers from the University of Tokyo and Osaka University have proposed the use of a free electron laser operating in the far infrared range. Without going into details, we can say that this laser is powerful enough to destroy the protein, but his power is not enough to "burn out the brain."

Free electron laser can be used to destroy the relationship between the structure of amyloid protein, - says one of the authors of Professor Koichi Tsukiyama. We wanted to demonstrate that these lasers can be used not only in the laboratory, but also in order to help people.

is not so innovative methods in process basis. In order to destroy the protein necessary to cause damage to its structure. The simplest example - frying eggs in a pan. Upon heating, we are destroying the structure of the egg protein, causing it to clot. Something similar scientists want to use in this case. The only problem is that you want to save the brain tissue. Therefore, the heating, as you know, will not work. Here I come to the aid and the laser.

In a series of experiments (so far only in a laboratory cell culture) we found out that the effect of the laser destroys the structure and hydrogen bonds in clusters DFKNF peptide. This peptide is responsible for, so to speak, "the preservation of the general form" of the protein, being something of its "skeleton". Moreover, the laser is able to cleave peptide DFKNF into separate parts, which prevents its recovery in the future. Well, the most interesting: "open the skull of" do not have such a procedure. The laser can penetrate deep into the tissue with little or no surgery. Of course, until the invention of new methods of treatment too early, but scientists from the rising sun set very optimistic and want to continue their studies.
