Peter and Jane Medawar wrote the following a few years ago: “It has been truly said that viruses are bad news clippings wrapped in protein.” They shot at the trial. When a virus infects a cell, Its genes – the “bad news” – Can, And often do, Disrupt the normal activities of the cell. Damaged cells may end up dying or malfunctioning, causing · Disease in the body. The truth is that it was through the visible damage inflicted by viruses on plants and animals alteration cellular functions that science learned of their existence. Today the pathologist or virologist who suspects the existence of a viral. Infection will begin by observing, Under the microscope, The cells infected in a trance of death, With their membranes crossed by viral particles in disarray, While the lymphocytes and other immune cells approach as riot police to contain the infection.
were believed to be supportive elements
Too, Injure tissues. If these indicators are found, The patient’s blood, Urine, And tissues will be investigated for the presence of antiviral antibodies, Genes, and viral proteins, With the idea of identifying the causative virus. In the absence of these clues, The viral hypothesis of the problem in question is usually ruled out. And against the Computer Software business email list toxicity of some phenols that could accumulate as a consequence. Of the hepatic metabolism of natural substances and some drugs. Also participate in the regulation of body temperature in animals and promote certain evolutionary processes. When dealing with the functioning of the human brain, We tend to immediately place ourselves in a neural perspective. Neurons, Excitable cells, Allow the processing of information in the brain by transmitting complex electrical signals
Oncological resistance to multiple drugs
The surprise of the listener is therefore justified when it is made known that more. Than half of the brain volume is occupied by cells. Of these, Neuroglia or “Nerve glue”, If we pay attention to its etymology, Constitutes the main class. And within glial cells, Astrocytes, Or stand out. So called because of their star shape, Astrocytes have been known Sale Lead since the late 19th century. For a long time, They were attributed a merely structural, passive or function of neurons. However, In just over a decade, That opinion changed radically thanks to advances in the methods of identifying and culturing astrocytes, which allowed a better understanding of their functions. Today we know with certainty that astrocytes have fundamental missions in normal physiology, In the development of the brain.
