Suppressive effects of ultraviolet radiation on the immune system
Human exposure to solar ultraviolet radiation (UVR) can exert a variety of biological effects, including induction of skin cancer, exacerbation of infectious diseases, premature skin ageing and inhibition of the immune system. The immunosuppressive properties of UVR are of major biological relevance since suppression of the immune system is related to a variety of diseases, ranging from the exacerbation of infectious diseases to the induction of skin cancer. The evidence shows that UVR can influence the immune system, cause damage to DNA, disturb the metabolism of Urocanic acid (UCA), and alter cellular redox equilibrium leading to free radical formation and membrane lipid peroxidation. Finally, UVR can induce contact hypersensitivity (CHS) and delayed type hypersensitivity (DTH). These changes might be related to local and systematic immunosuppression. Hence, understanding the immunosuppressive mechanisms of UVR in human diseases becomes of primary importance in the protection and improvement of human health.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
