An international team of scientists have observed a previously unclear inflammatory mechanism caused by airborne particles that can worsen asthma symptoms, it has been reported in Toxicological Sciences.

As the world gets more and more industrialized, the risk of developing respiratory diseases increases. Very small particles released from industry and vehicle fumes are harmful to our health but exactly how is still unclear. In a collaborative study, researchers in Japan, the US and Germany have uncovered one mechanism that can exaggerate inflammation in response to diesel fumes and worsen symptoms of respiratory diseases.
