What happens to the brain cell after, how does she die We offer a look at this process., in the center of which there is only one neuron.
Programmed death of old neurons or apoptosis is a natural process of the body’s life. Removing dead cells and dendrites that bind them to other neurons is critical to the normal functioning of the central nervous system. If this process is impaired, especially at an early age, then in the future it may lead to impaired development of the nervous system and cognitive impairment.
Researchers from the neurobiological laboratory of Jaime Gruecendler of Yale University Eyemisi Damis and Robert Hill for the first time took pictures of this process at the level of one neuron. The work of scientists, in which it is shown how specialized brain cells are involved in the removal of dead neurons and dendrites from the central nervous system, at Science Advances. Researchers say a detailed understanding of the disposal of dead brain cells will help in the treatment of diseases of the central nervous system that occur in old age.
Specialized grave-digger cells that remove dead neurons from the brain are called microglial cells and astrocytes. Microglia flock to the dead cell, surround it, and then absorb along with the nearest processes. At this time, other brain cells – astrocytes, so named because of the star shape, help remove long processes of neurons.
