The study analyzed nearly 3 million privately insured adults and found that those with seven or more chronic conditions had three to four...
A deficiency in gene regulation disrupts the clearance of surfactant lipids in alveolar macrophages, leading to their bloating and foaming. This defect is associated with conditions like pulmonary alveolar proteinosis, obesity, and atherosclerosis.
A study reveals that alveolar macrophages, responsible for filtering bacteria and viruses from the lungs, fail to function properly when lacking a crucial transcription factor called C/EBPb. This leads to an accumulation of surfactant in the lungs, causing pulmonary alveolar proteinosis (PAP), a hitherto incurable disease.
