The Role and Potential Pathogenic Mechanism of Particulate Matter in Childhood Asthma: A Review and Perspective

Abstract EN

Asthma, the most common chronic respiratory disease in children, affects numerous people worldwide.

Accumulating evidence suggests that exposure to high levels of particulate matter (PM), either acutely or chronically, is associated with the exacerbation and incidence of pediatric asthma.

However, the detailed pathogenic mechanisms by which PM contributes to the incidence of asthma remain largely unknown.

In this short review, we summarize studies of relationships between PM and pediatric asthma and recent advances on the fundamental mechanisms of PM-related asthma, with emphases on cell death regulation and immune system responses.

We further discuss the inadequacy of current studies and give a perspective on the prevention strategies for pediatric asthma.
