Glyphosate, whose toxicity has been shown in both in vitro and in vivo studies to affect inflammation in lung and airway tissues, has also been shown to cause higher amounts of eosinophils, neutrophils, and asthma-related cytokines (IL-5, IL-10, IL-13, IL-33, TSLP), which result in narrowing of the airway [11, 48, 49]. Here, TSLP is linked to asthma.
