Abstract EN
There are numerous studies concerning the effect of UVB light on skin cells but fewer on other skin components such as the interstitial fluid.
This review highlights high-density lipoprotein (HDL) and low-density lipoprotein (LDL) as important targets of UVB in interstitial fluid.
Tryptophan residues are the sole apolipoprotein residues absorbing solar UVB.
The UVB-induced one-electron oxidation of Trp produces •Trp and O2•- radicals which trigger lipid peroxidation.
Immunoblots from buffered solutions or suction blister fluid reveal that propagation of photooxidative damage to other residues such as Tyr or disulfide bonds produces intra- and intermolecular bonds in apolipoproteins A-I, A-II, and B100.
Partial repair of phenoxyl tyrosyl radicals (TyrO•) by α-tocopherol is observed with LDL and HDL on millisecond or second time scales, whereas limited repair of α-tocopherol by carotenoids occurs in only HDL.
More effective repair of Tyr and α-tocopherol is observed with the flavonoid, quercetin, bound to serum albumin, but quercetin is less potent than new synthetic polyphenols in inhibiting LDL lipid peroxidation or restoring α-tocopherol.
The systemic consequences of HDL and LDL oxidation and the activation and/or inhibition of signalling pathways by oxidized LDL and their ability to enhance transcription factor DNA binding activity are also reviewed.
