Selective RAR agonists for acne vulgaris: A narrative review.
2019
Background Acne vulgaris is a chronic disfiguring inflammatory disease of adolescents and adults affecting up to 90% of the population around the world. The sequence of etiopathogenesis in acne is not completely understood but involves abnormalities in sebum production, follicular plugging, proliferation of propionibacterium acnes, and chronic inflammation. Aims This review aims to summarize the features of the topical selective RAR agonists in treating acne vulgaris with a special emphasis on the 4th generation topical retinoid trifarotene. Methods Studies were identified by searching electronic databases (MEDLINE and PubMed) till August 2019 and reference lists of respective articles. Onl…
Analysis of a soluble lipid-protein complex carrying endogenous 11-cis retinaldehyde from bovine retinal pigment epithelium.
1989
A soluble lipid-protein complex in bovine retinal pigment epithelium is shown to carry endogenous 11-cis retinaldehyde, in the extent of 15% of the total 11-cis retinaldehyde found in this tissue. The complex, analyzed with respect to its chemical composition, exhibits a lipid composition close resembling the lipid composition of the rod outer segment membrane; the SDS-PAGE evidences the presence of a number of protein bands, two of which of 34 and 27 kDa appear glycoproteins. Finally, the lipid-protein complex exhibits a discrete level of a Cathepsin D-like protease activity. From the above, the possibility is discussed that the soluble lipid-protein complex could represent some phagolysos…
