Usually people recover from the flu within one or two weeks, but complications like pneumonia persist in patients even after the destruction of all viral particles. Researchers from the University of Pennsylvania decided to reveal the cause of this phenomenon, and studied the structure of the lungs of laboratory mice ill with “swine flu”. It turned out that in serious cases, the virus changes the structure of the lungs, and appear in them taste buds. According to scientists, they are the cause of complications.
Researchers already knew that in the flu epithelial cells that line the alveoliis dying. The resulting recesses are quickly replenished by the surrounding cells to prevent violations of the structure of the alveoli. When this occurs, a side effect of the resulting “patches” can not perform the function of gas exchange with pulmonary capillaries, which leads to further health problems.
The study of organisms had been ill with influenza mice showed that the formed holes may occur and the taste buds. The same cells were previously detected in the intestine and the oral cavity — they react to the bitter taste and helps the body to release anti-inflammatory substance against poisons and toxins. Apparently, in the lungs they perform the same function, but their reproduction occurs dangerous effect of inflammation.
According to the researchers, these cells can also be the cause of development and other diseases, such as asthma. Knowing this, scientists have another possibility to cure the effects of flu. However, before drug development, researchers must ensure that the same reaction occurs in humans — after all, the experiment was carried out on mice.
