Our skin’s epithelial cells send electrical signals like neurons to cry out for help ...

A new study uncovers a surprising mechanism by which the SARS-CoV-2 virus, responsible for COVID-19, might cause immune-mediated tissue damage by targeting cells it has never infected.

Thetis cells, a class of immune cells first described in 2022, play an essential and previously unknown role in suppressing inflammatory responses to food, a new study finds.

Both sepsis and bacteremia involve bacteria in the bloodstream. Bacteremia generally is not a serious condition, but sepsis can be life-threatening.

SARS-CoV-2 persists in the epipharyngeal (a region behind the nasal cavity) mucosa of patients with long COVID. However, the impact of these persistent viral antigens on the epipharyngeal immune ...

Finally, single-cell RNA sequencing data indicated that Plscr1 expression was significantly upregulated in ciliated airway epithelial cells in mice following IAV infection.

The strain lacks the dermonecrotic toxin gene, coding for a highly toxic protein, has undetectable levels of tracheal cytotoxin, a peptidoglycan breakdown product that can destroy ciliated epithelial ...

Study Found Beethoven's 5th Symphony Destroyed 20% of Cancer Cells in Lab Tests — Or Did It? A Brazilian research team's findings on lab cell cultures were distorted. The lead scientist then ...

Compared with other methods, urine Gram stain moderately predicted gram-negative bacteria but added little value to UTI diagnosis in the ED, raising questions about its clinical utility.
