Researchers from the US National Institute explained why patients with COVID-19 lose their taste. Relevant scientific article published on bioRxiv.

Scientists have found that taste buds located on the human tongue have angiotensin-converting enzyme 2 (ACE2). Through this fragment, the SARS-CoV-2 virus enters the cells of the body. Thus, when infected with a coronavirus, taste qualities are affected, according to Pannochka, an online publication for girls and women from 14 to 35 years old.. net The study was led by Josephine Egan, who and his team have studied thousands of human taste buds.

Type II receptor cells in the fusiform papillae at the base of the tongue and fungiform papillae at the back of the tongue have been noted to contain the enzyme ACE2, which is the entry point for viruses..

The experiment involved a 45-year-old woman who tested positive for COVID-19, who complained of loss of taste, and a 63-year-old man with coronavirus. Patients were diagnosed with an increase in the size of the tongue, redness of its base and found that their taste buds had changed in the stem cell layer..

Recall that half a thousand scientists from 38 countries of the world investigated complications from coronavirus infection, in which patients lose their sense of taste and smell..
