A Cytokine Cascade Including Prostaglandin E2, IL-4, and IL-10 Is Responsible for UV-Induced Systemic Immune Suppression

Shreedhar, Vijay, Giese, Todd, Sung, Victor W, Ullrich, Stephen E·1998·The Journal of Immunology

Abstract

Even though all of the energy contained with the UV wavelengths of solar radiation is absorbed within the epidermis and upper layers of the dermis, UV irradiation can suppress immune responses to Ag introduced at distant nonirradiated sites. In addition, data from a number of laboratories have suggested that one consequence of UV exposure is suppressed Th1 cell activation with normal or enhanced Th2 cell activation, resulting in a shift to a Th2-like phenotype. Cytokines secreted by UV-irradiated keratinoctyes, particularly IL-10, have been shown to play a major role in the induction of systemic immune suppression and differential activation of T helper cell subsets. Although IL-10 can influence Th1 cell activation by altering Ag presentation and suppressing IFN-γ secretion, the major signal for the development of a Th2 response is IL-4. Here we tested the hypothesis that UV irradiation induces IL-4 secretion. UV irradiation induced serum IL-4 in a dose-dependent fashion. Injecting UV-irradiated mice with anti-IL-4 blocked immune suppression. We could find no evidence, however, supporting secretion of IL-4 by UV-irradiated keratinocytes. Rather, we suggest that prostaglandins released by irradiated keratinocytes induce serum IL-4 since treating UV-irradiated mice with a cyclooxygenase-2 inhibitor blocked its production. Moreover, we found that treating UV-irradiated mice with anti-IL-4 suppressed serum IL-10 levels. In addition, injecting normal mice with PGE2 induced serum IL-4 and IL-10. We suggest that UV exposure activates a cytokine cascade (PGE2 → IL-4 → IL-10) that ultimately results in systemic immune suppression.

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.
