A group of scientists from Duke University Medical Center in the United States said that the reason some people fail to recover their sense of smell after being infected with the new crown is related to the continuous immune attack of olfactory nerve cells and the decrease del the number of related cells.
The study found that COVID-19 caused an abnormally active immune system response within the human nose, also decreased the number of olfactory sensory neurons, possibly due to destruction of fragile tissue due to persistent inflammation .
Encouragingly, neurons appear to retain some ability to repair even after a long-term immune attack. The researchers hope that modulating abnormal immune responses or repair processes in patients’ noses could help restore at least some sense of ‘smell.
The findings were published in the journal Science Translational Medicine, and while focusing on the loss of smell, the study also reveals potential causes of other COVID-19 symptoms, including general fatigue, shortness of breath and brain fog, which could be triggered by a similar biological mechanism. mechanism.
