What are gli cells?

Gli cells or gliia are specialized cells found in the nervous system that support its functions. Historically, they were not strongly studied because scientists were more interested in neurons and believed that gli cells functioned primarily as mortar to hold the nervous system together. Research in the 1960s began to reveal that these cells actually played a number of important roles, including the ability to signal each other and control signaling with other cells. Studies of their function are important to understand how the nervous system works and recover from injury. A specific subtype known as oligodendrocyte produces myelin, which protects neurons from it and regulates the movement of signals. Gli cells, such as astrocytes, offer structural support that holds neurons in a position and also provide food and cleaning. As the neurons produce waste, the surrounding cells remove it for processing. Othas glial cells known as microglia can attack invasive organisms and absorb dead neurony to remove.

neuron -working scientists must grow glii next to them to provide the necessary support. Otherwise, neurons cannot survive in culture. The exact equilibrium of numbers between glial cells and neurons is subject to discussion; It was originally assumed that it was about nine to one, but further research suggests that more neurons may be present than originally believed scientists who try to calculate them. Overall, more glial cells than neurons are present in the nervous system, although the exact number is uncertain.

microgli is formed from bone marrow and are constantly renewed throughout their lives. Other cells develop from the nerve tube and comb, the same structures that lead to the rest of the nervous system. They are distributed throughout the central and peripheral nervous system provides support for different functions. The regulation of their environment is one of their most important tasks, allowing the complex neuroNeurons went through logical signals.

disorders may occur in glial cells. They may include cancer where cells begin to reproduce from control. For example, astrocytoma is cancer arising from astrocytes that occur when normal control mechanisms of the cell are off and are constantly dividing and growing. Treatment of these conditions may be complex because it may require surgery and other therapy in the fine areas of the brain, which could expose patients such as brain damage that leads to cognitive damage.
