It also suppressed TGF- activation and inflammatory cytokines, thereby resulting in the breakdown of the ECM accumulation pathway [58]
This can inevitably multiply damaged cells or free radicals
Furthermore, the levels of transcortin (or corticosteroid-binding globulin), the primary glucocorticoid-binding protein and a negative control protein, were substantially lower in IMDD patients than in controls [39]
[0079] Advantageous skin and hair tanning active ingredients in this respect are substrates or substrate analogues of tyrosinase such as L-tyrosine, N-acetyl tyrosine, L-DOPA or L-dihydrox- yphenylalanine, xanthine alkaloids such as caffeine, theobromine and theophyl-line and de rivatives thereof, proopiomelanocortin peptides such as ACTH, alpha-MSH, peptide analogues thereof and other substances which bind to the melanocortin receptor, peptides such as Val- Gly-Val-Ala-Pro-Gly, Lys-lle- Gly-Arg-Lys or Leu-lle-Gly-Lys, purines, pyrimidines, folic acid, cop per salts such as copper gluconate, chloride or pyrrolidonate, l,3,4-oxadiazole-2-thiols such as 5-pyrazin-2-yl-l,3,4-oxadiazole-2-thiol, curcumin, zinc diglycinate (Zn(Gly)2), manganese(ll) bicarbonate complexes ("pseudocat-alases") as described for example in EP 0 584 178, tetrasubstituted cyclohexene deriva-tives as described for example in WO 2005/032501 , iso- prenoids as described in WO 2005/102252 and in WO 2006/010661 , melanin derivatives such as Melasyn-100 and MelanZe, diacyl glycerols, aliphatic or cyclic diols, psoralens, prostaglan dins and ana-logues thereof, activators of adenylate cyclase and compounds which activate the transfer of melanosomes to keratinocytes such as serine proteases or agonists of the PAR- 2 receptor, extracts of plants and plant parts of the chrysanthemum species, san-guisorba species, walnut extracts, urucum extracts, rhubarb extracts, microalgae extracts, in particular Isochrysis galbana, trehalose, erythru-lose and dihydroxyacetone
