ACE2 allows the virus to enter nasal cells, while TMPRSS2 helps activate the virus by cleaving its spike protein. Those with high expression for these proteins were more than three times as likely ...

Important differences in how the nasal cells of young and elderly people respond to the SARS-CoV-2 virus, could explain why children typically experience milder COVID-19 symptoms, a new study finds.

The researchers discovered that when mice were given a nasal vaccination, a focused immune response was mounted by B cells, the immune system's key producers of antibodies. These cells begin their ...

Cartilage grown from human nose cells has been used to repair serious KNEE injuries. Engineered cartilage from nasal septum ...

Researchers have claimed that people who lost their sense of smell after contracting Covid may have an ongoing, abnormal immune response that destroys cells in the nose, a news report stated.

Inside the sticky confines of the human nose, a gluey layer of mucus surrounds small hairs and cells. While this ooze may appear gross, it is teeming with important components of the immune system.

The following is a summary of “Towards precision medicine: inflammatory nasal epithelial transcriptomic profiles in long COVID,” published in the June 2025 issue of Journal of Allergy and Clinical ...

Important differences in how the nasal cells of young and elderly people respond to the SARS-CoV-2 virus, could explain why children typically experience milder COVID-19 symptoms, finds a new ...

The study, published in Nature Microbiology, focused on the early effects of SARS-CoV-2 infection on the cells first targeted by the viruses, the human nasal epithelial cells (NECs). These cells were ...
