光免疫学始于近40年前,发现了实验性光致癌过程中UVR和免疫抑制之间的联系。UVR诱导的皮肤肿瘤似乎具有高度抗原性,因为它们在接种到同基因小鼠中时被排斥(Kripke,1986)。接受免疫抑制药物治疗的受体不会对移植的肿瘤产生排斥反应,这与接受低剂量UVR而不是药物免疫抑制的受体类似,表明UVR抑制细胞免疫。改变免疫反应最有效的紫外线辐射光谱是中波范围(UVB,290-320 nm)。因此,大多数光免疫学研究都是用UVB进行的,尽管UVA(320-400 nm)肯定也对免疫反应有影响。除了皮肤肿瘤的发展之外,发现UVR抑制接触性超敏反应(Toews等人,1980年)。由于通过UVR暴露皮肤接受接触性过敏原的小鼠在几周后不能对相同的抗原重新敏感,因此得出结论,UVR诱导长期抑制。这似乎是抗原特异性的,因为没有改变其他免疫应答。由于UVR暴露和致敏作用影响相同的皮肤区域,因此该模型也被称为局部免疫抑制。后来的研究表明,紫外线辐射虽然剂量较高,但也可通过皮肤释放可溶性介质(IL-10,肿瘤坏死因子),以全身方式影响免疫系统(Ullrich和施密特,2000)。alarmin(细胞损伤时释放的内源性介质)IL-33是否有助于UVR诱导的免疫抑制有待进一步研究,尽管IL-33的中和阻断UVR诱导的免疫抑制的事实是相当令人信服的(Byrne等人,2011年)。
Photoimmunology started almost 40 years ago with the discovery of a link between UVR and immunosuppression during experimental photocarcinogenesis. Cutaneous UVR-induced tumors appeared to be highly antigenic, as they were rejected upon inoculation into syngeneic mice (Kripke, 1986). Recipients treated with immunosuppressive drugs did not reject the transplanted tumors, similar to recipients who had received low doses of UVR instead of pharmacological immunosuppression, indicating that UVR suppresses cellular immunity. The most effective UVR spectrum to alter an immune response turned out to be the mid-wave range (UVB, 290–320 nm). Thus, most of the photoimmunologic studies were conducted with UVB, although UVA (320–400 nm) certainly has an effect on immune reactions as well. Besides the development of skin tumors, UVR was found to inhibit contact hypersensitivity (Toews et al., 1980). As mice that received the contact allergen through UVR-exposed skin could not be resensitized against the same antigen a few weeks later, it was concluded that UVR induces long-term suppression. This appeared to be antigen specific, as no other immune responses were altered. As UVR exposure and sensitization affect the same skin area, this model is also referred to as local immunosuppression. Later studies showed that UVR, although at higher doses, can also affect the immune system in a systemic manner via the release of soluble mediators (IL-10, tumor necrosis factor) from the skin (Ullrich and Schmitt, 2000). Whether the alarmin (endogenous mediators released upon cellular injury) IL-33 contributes to UVR-induced immunosuppression awaits further investigation, although the fact that neutralization of IL-33 blocks UVR-induced immunosuppression is quite convincing (Byrne et al., 2011).
