Protection against a widespread fatal disease is called


Scientists of the University Colombia (USA) and Tauba Institute found out that hormone иризин, developed by a brain during physical exercises, improves memory and reduces risk of development of Alzheimer's disease — an incurable form of dementia terminating in death. It is reported in the press release on MedicalXpress. Scientists analysed samples of brain tissue of patients with Alzheimer's disease and found out that at patients in a hippocampus (the department of a brain which is responsible for memory formation) the content of hormone decreases. Experiments on mice showed what иризин in a brain of rodents protects synapses (contacts between neurons) from damages which can cause damage to memory. At a shortcoming rubber in a hippocampus at animals problems with memory and weakening of synapses are observed. Mice who swam every day within five weeks did not show symptoms of dementia even at introduction beta амилоидов — peptides which as it is considered to be, contribute to the development of Alzheimer's disease in the person. However blocking of activity of an irizin completely removed positive effect from physical activity. Results of a research show that hormone can be used as therapy of dementia at people. Scientists plan to pick up medicines which can provoke development of an irizin or have the effect similar to effect of hormone. Irizin is formed at the strengthened muscle work. It is also established that this connection plays a role in metabolism, in particular, promotes transformation of white fat into brown. However recently experts found proofs that иризин participates also in growth of nervous cages in a hippocampus. At the moment more than 26 million people are sick with a deadly form of dementia, and it is expected that by 2050 their number will become four times more. Gradually patients have a loss of long-term memory, there are violations of the speech and cognitive functions, eventually, patients lose ability to look after themselves.
