A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Researchers identify a genetic defect in alveolar macrophages that causes lung disease

New discovery on the causes of PAP lung disease can also offer solutions for treating obesity and heart disease. The research group of Associate Professor Alexander Mildner at the University of Turku, Finland, identified a genetic defect that causes the accumulation of lipids in the pulmonary alveoli.

Research reveals pivotal role of C/EBPb in the development of alveolar macrophages

If a secretion in the lungs’ alveoli is not cleared regularly, breathing difficulties can develop. In a study published in Science Immunology, a team led by Alexander Mildner and Achim Leutz has now explained the pivotal role of the transcription factor C/EBPb in this process.

Parenteral-prime mucosal boost an effective strategy to protect against SARS-CoV-2

In a recent study published in the journal eBioMedicine, researchers in Denmark and Sweden administered a cationic liposome-adjuvanted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein subunit vaccine as a subcutaneous (s.c.) prime-intranasal (i.n.) boost strategy to elicit mucosal immune responses among SARS-CoV-2-infected Syrian hamsters.

Study identifies mechanism behind 'cytokine storm' in COVID-19 patient lungs

A new study by HSS Research Institute scientists identifies a mechanism by which SARS-CoV-2 induces the inflammatory response in COVID-19 patient lungs, so-called "cytokine storm", that can lead to lasting tissue damage and poor patient outcomes.

Age-related changes in microbiome composition affects brain macrophages

Scientists review the impact of age-related gut microbiome composition on age-associated diseases caused by dysfunctional macrophages within the brain.

Pollutant particles in the air trigger lung cancer in non-smokers

A new mechanism has been identified through which very small pollutant particles in the air may trigger lung cancer in people who have never smoked, paving the way to new prevention approaches and development of therapies, according to late-breaking data [to be] reported at the ESMO Congress 2022 by scientists of the Francis Crick Institute and University College London, funded by Cancer Research UK. The particles, which are typically found in vehicle exhaust and smoke from fossil fuels, are associated with non-small cell lung cancer (NSCLC) risk, accounting for over 250,000 lung cancer deaths globally per year.

Study establishes link between Piezo1 and intracellular cholesterol levels during neural development

A new University of California, Irvine-led study reveals how mechanical forces and tissue mechanics influence the morphology of the developing brain, and establishes a direct link in neural stem cells between Piezo1, a mechanically-activated ion channel, and intracellular cholesterol levels during neural development.

Soft-tissue sarcomas produce a protein that make immune cells 'go bad'

Investigators from Cedars-Sinai Cancer have discovered that cancerous tumors called soft-tissue sarcomas produce a protein that switches immune cells from tumor-attacking to tumor-promoting.
