TOMSK, Sep 22 – RIA Tomsk. Scientists of the RASA Center at the Tomsk Polytechnic University (TPU) intend to develop the nanocapsules operated by magnetic field which will deliver medicine selectively to the concrete site of a brain, allowing to treat the cells of a brain damaged at a stroke, the press service of the University reported on Thursday.
It is noted that there are two types of strokes – ischemic and hemorrhagic. At the first blood clot blocks the artery or capillary in the brain, at the second – the blood vessel is broken off, and the hemorrhage occurs. At the damage of vessels in the organism protective cells are activated – leucocytes, but in a case with the stroke their high concentration can cork the vessel even more and damage more cells of the brain.
"To prevent this, we can help "defenders" of our body to really solve, rather than exacerbate the problem. For example, "to attach" to a leukocyte a nanoparticle with medicine against blood clots. Thus, the organism itself will treat the damaged site of the brain vessels. This will save the patient's brain from bigger damage", – quoted in the message the project manager Dmitry Atochin.
It is added that to do address delivery of medicines in affected areas of the brain is planned by means of magnetic field. In the long term by means of "remotely-controlled" medicines it will be possible to struggle with blood clots in vessels, reducing risks of developing of strokes and other diseases.
It is added that the research will become "pioneer". And at successful result it will allow to bring treatment and prevention of strokes to the new level.
Earlier it was reported that at the beginning of 2016 in TPU the laboratory which scientists are engaged in development of remotely-controlled systems for delivery of drugs in a concrete point of an organism of the patient opened. The laboratory was headed by professors Gleb Sukhorukov (Queen Mary University of London) and Dmitry Gorin (Saratov State University).
