It took a while but finally our paper went online in Toxicology Letters. The paper emerged out of the SAS4REACH consortium in which we discussed the pathology outcome of 14 different particles after subchronic inhalation. The fact that inflammation occurs after most particle exposures is not new, and frustrating classification. However, during post-exposure follow-up differences appear between particles. In this paper we used available data from crystalline and amorphous silica’s to have a closer look at the “adversity” of pulmonary inflammatory response. Not all inflammation is persistent and not all inflammation leads to tissue changes that cannot be repaired. Time to open our minds and have an renewed look at our testing checklists!
