Agr quorum sensing drives S. aureus skin colonization in AD infants. The risk of developing AD was significantly higher in infants who were colonized with S. aureus at six months. The agr mutations of S. aureus occurred in strains from those infants who did not develop AD, while no agr mutations of S. aureus were identified in the infants who did develop AD. Epicutaneous S. aureus colonization mouse model revealed that the Agr-QS system plays a critical role in the development of AD-like inflammation. The photos and pathological images of mice were adapted from (Nakamura et al., 2020). HE, Hematoxylin-Eosin Stain; HPF, high power field; LPF low power field.
