A new study led by Professor Akiko Iwasaki of the Howard Hughes Medical Institute and Professor Vishwa Deep Dixit from Yale School of Medicine shows that...

Elliot et al show that fatty tissue is present within the airway wall and is related to BMI, wall thickness and the number of inflammatory cells. The accumulation of airway fatty tissue in overweight individuals may therefore contribute to airway pathophysiology. Image credit: Kalhh.

Fatty Tissue Accumulates in Airways of Overweight and Obese People, New Study Finds

According to a new study published in the European Respiratory Journal, fatty tissue accumulates within the airway walls of people who are overweight or...

Bradley et al identify lung stroma as the target of microbiota-driven signals that set the interferon signature in these cells; antibiotic treatment reduces gut microbiota and the lung stromal interferon signature and facilitates early influenza virus replication in lung epithelia, effects that can be reversed by fecal transplantation.

Study: Gut Bacteria Stimulate Antiviral Signals in Lung Cells to Protect against Flu Virus

Jul 8, 2019 by News Staff

In a study of mice, an international team of scientists has discovered that signals from gut bacteria help to maintain a first line of defense in the lining...

Mycobacteria are frequently abundant in showerheads, and many showerheads harbor mycobacterial lineages that include known pathogens.

New Study Finds Correlation between Showerhead Bacteria and Lung Infections

Nov 2, 2018 by Enrico de Lazaro

Bacteria thrive in showerheads and throughout household water distribution systems. While most of these bacteria are innocuous, some are potential pathogens,...

Asthma sufferers have trouble breathing because of the narrowing of the airways in their lungs, an example of which is shown in the upper left. In chronic asthma (lower left), repeated cycles of inflammation, damage, and repair lead to airway remodeling and fibrosis, the buildup of collagen and other materials. A signaling molecule known as NF-κB can significantly reduce chronic asthma (lower right). Image credit: National Institute of Allergy and Infectious Diseases.
