Background:
Tretinoin(Aberela) is retinoic acid in pharmaceutical form and used to treat acne vulgaris and keratosis pilaris.
In cultured human mesangial cells, tretinoin increased the reduced glutathione content and the catalase activity in a dose- and time-dependent way, which then prevented the cytotoxicity of H2O2 [1].
In old male Fischer 344 rats, tretinoin inhibited the expression of TNF-β1 and osteopontin (a protein with chemotactic and cell adhesive properties) in the renal cortex [1]. In male NMRI-mice treated with 1×109 sheep red blood cells (SRBCs), tretinoin markedly inhibited cellular immunity and increased humoral immunity. Tretinoin reduced lymphocyte proliferation, NBT reduction and the secretion of interleukin-17, but increased the production of interleukin-10 [2]. In patients with facial acne, clindamycin phosphate Tretinoin Gel (CTG) (1.2% clindamycin phosphate, 0.025% tretinoin in a gel base (Velac)) was significantly more effective than 0.025% tretinoin, which relayed on the anti-inflammatory efficacy of tretinoin [3].
