Abstract

Extrinsic atopic dermatitis (EAD) and intrinsic atopic dermatitis (IAD) patients suffer from recurrent bacterial and viral infections. In this study, we demonstrate significantly decreased expression of human beta defensin (HBD)-3, a potent antimicrobial peptide (AMP), in lesional skin of both IAD (p<0.01) and EAD patients (p<0.01), as compared to psoriasis patients. Using primary keratinocytes from EAD and IAD patients, we determined that the deficiency in HBD-3 expression is an acquired rather than a constitutive defect. Furthermore, we demonstrate the down-regulatory effect of IL-4, IL-10, and IL-13 - which are over-expressed in the skin of AD patients - on HBD-3 expression in keratinocytes. Additionally, treatment of EAD skin explants with antibodies against IL-4, IL-10, and IL-13 augmented the expression of HBD-3. These studies suggest that neutralizing the Th2 cytokine milieu in AD skin may augment the innate immune response against bacterial and viral pathogens.

  • AMP expression is highly dependent on the cytokine milieu present in the skin and proinflammatory cytokines such as IL-1, IL-6, IL-8, and TNFα are typically strong inducers of AMPs, whereas IL-4, IL-13, and IL-10 have been shown to dampen AMP responses.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
