Blood Test for IL-32 May Diagnose COPD, Measure Severity, Study Says
A blood test to measure levels of the immune signaling protein interleukin-32 (IL-32) may be a useful biomarker to diagnose and assess the severity of chronic obstructive pulmonary disease (COPD), a new study suggests.  The study, “Correlation between serum IL-32 concentration and clinical parameters of stable COPD: a retrospective clinical analysis,” was published in the journal Nature Scientific Reports Chronic inflammation in the lungs is a hallmark of COPD. The imbalance of various inflammatory mediators, including immune system signaling proteins — known as cytokines — play an essential role in small airway inflammation. IL-32 is an inflammatory cytokine secreted by a variety of immune cells. Studies have shown that IL-32 is produced at high levels in the lungs of people with COPD and participates in the inflammatory process.  The prevalence of COPD has increased among Chinese people year by year, primarily due to
