Popis: In addition to its genotoxic and mutagenic effects, UV has the capacity to suppress immune responses. The mechanism involved is complex, beginning with chromophores located in the skin which absorb UV, this leading in turn to changes in the production of a range of immune mediators locally and systemically which then induce phenotypic and functional alterations in antigen presentation. The cascade ends with the promotion of a subset of T-cells downregulating cell-mediated immunity. The possible consequences of this immunomodulation for the control of tumours and infectious diseases require careful evaluation from laboratory and human studies.
