The mechanism of aging of a brain is cracked


Scientific Clinics of Mayo have found out that the senestsentny, that is grown old cages which have stopped division and emitting pro-inflammatory substances promote weak-mindedness. Biologists managed to prevent their emergence and to stop the death of neurons connected with development of dementia. It is reported in MedicalXpress. During the research experts used genetically modified mice subject to accumulation of the tau-proteins forming neurofibrillary tangles which are found at Alzheimer's disease. Besides, at a number of rodents the ways promoting death of senestsentny cages have been activated. In this case at animals signs of inflammation disappeared, congestions of tau-proteins weren't formed, and the mass of a brain remained within norm. Scientists have found out that the growing old cells of the central nervous system (CNS) concerned two types — a microglia and astrotsita. The microglia is immune cages (resident macrophages) who almost don't participate in fight against infectious agents, but promote destruction of the damaged neurons and other TsNS components. Astrotsita support neurons, regulate a reserve of nutrients and growth of nervous tissues. It is more than important news in Film of Day Telegram-channel. Subscribe!
