Bacterial protein fragment corisin found to drive pulmonary fibrosis

A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell's quality-control system, researchers at the University of Illinois Urbana-Champaign and Mie University in Japan found in a new study.

Catheter-directed thrombolysis improves short-term outcomes in pulmonary embolism patients

In patients with intermediate−high risk pulmonary embolism, catheter-directed thrombolysis improved short-term clinical outcomes compared with standard anticoagulation therapy alone, according to results presented in a Hot Line session today at ESC Congress 2026.

Newly discovered lung immune cells could transform future flu vaccine design

Influenza continues to cause major illness each year in the United States, leading to more than 35,000 deaths annually. Children, older adults, pregnant individuals, people with weakened immune systems, and those with chronic conditions such as heart disease, metabolic disorders, and cancer are especially vulnerable.

Specialized blood vessel cells found to actively drive lung fibrosis

Millions of people worldwide are affected by diseases that cause scarring of the lungs, often leading to breathing difficulties and reduced quality of life.

Newly identified cells protect lung tumors from immune attacks

Researchers at Columbia University have discovered a new type of cell that protects lung cancers from attacks by the immune system.

Researchers tested dozens of clues for long COVID. One finding stood out

A nationwide study of 218 people in the Faroe Islands examined clinical, neurological, and blood-based markers associated with persistent symptoms around six months after SARS-CoV-2 infection. Despite extensive testing, researchers found no convincing biomarker for long COVID, while a statistical association with lower INR remained within the normal clinical range and requires replication.

Women with shorter reproductive lifespan face higher risk of developing bronchiectasis

Women with a shorter reproductive lifespan are at greater risk of developing bronchiectasis, according to a new study in the July 2026 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open access journal.

Overuse of short-acting bronchodilator linked to increased risk of cardiovascular diseases and death

Overuse of reliever inhalers is associated with higher risks of developing and dying from cardiovascular disease, including heart failure, heart attack and ischemic stroke, in asthma and COPD patients, according to a study published today in ERJ Open Research.

Study links thymus radiation to worse lung cancer outcomes

Until recently, the thymus was thought to be of little use beyond puberty, but new research has shown that radiation to the organ is associated with worse outcomes in patients being treated for non-small cell lung cancer (NSCLC).

Gene removal makes engineered immune cells more effective against osteosarcoma

Scientists at St. Jude Children's Research Hospital have discovered that removing the gene for Regnase-1 from engineered immune cells makes them more effective at treating relapsed osteosarcoma.

Mitochondrial transplantation helps repair donor organs during machine perfusion

Transplant medicine still depends on a limited supply of donor organs, while many retrieved grafts are discarded because ischemia, cold storage, and reperfusion can rapidly damage their cells.

Higher BPA exposure tracked with higher estrogen and progesterone in women

Researchers found that higher urinary concentrations of BPA and several phthalate metabolites were associated with higher serum estrogen and progesterone levels in 90 premenopausal women from Iran. The cross-sectional study also identified positive associations for combined chemical exposures, although the authors cautioned that the mixture findings are exploratory and cannot establish causality.

California landscapes linked to differing rates of Valley fever

Researchers from University of California San Diego and University of California, Berkeley have found that certain landscapes surrounding California communities are associated with differing rates of Valley fever, a fungal respiratory infection caused by inhaling spores carried in windblown dust.

New study makes progress in understanding the mechanisms behind severity of HFpEF

Approximately 3 million people in the United States are living with a condition called heart failure with preserved ejection fraction, or HFpEF.

Only 15% of eligible American adults discuss lung cancer screening with their doctors

Lung cancer screenings can save lives by detecting cancer in its early stages, but only 15% of eligible American adults have discussed the screening with their doctors, according to data analysis performed by University of Cincinnati Cancer Center researchers.
