Cím:	The TRPM5 antagonist triphenylphosphine oxide increases sebaceous lipogenesis and modulates immune phenotype of human sebocytes in a TRPM5-independent manner / Ádám D., Arany J., Tóth K. F., Petö O., Nyitrai T., Tóth B. I., Póliska S., Zouboulis C. C., Oláh A.

Megjegyzések:	It has recently been shown that transient receptor potential melastatin 5 (TRPM5) ion channels contributed to the maintenance of the anagen phase of the hair cycle. Because adjacent sebaceous glands also exhibited TRPM5 immunopositivity, topically applied TRPM5 modulators administered with the intention to influence hair growth may also affect sebaceous glands (SGs). Hence, we aimed to assess expression of TRPM5 as well as effects of 2 agonists and 1 antagonist (triphenylphosphine oxide [TPPO]) of TRPM5 on human SZ95 sebocytes. First, using complementary methods (RNA-Seq, RT-qPCR, western blot, siRNA-mediated gene silencing, fluorescent Na+- and Ca2+-measurements), we found that TRPM5 is not expressed in human sebocytes in a functionally active form.While non- cytotoxic (MTT-assay) concentrations of the activators were ineffective, TPPO promoted sebaceous lipogenesis (Nile Red). This effect was TRPM5-independent and was found to be mediated in an Akt- and epidermal growth factor receptor (EGFR)-dependent manner, most likely via the Akt-induced up-regulation of diacylglycerol O-acyltransferase-2. Moreover, TPPO up-regulated interleukin (IL)-6 in an EGFR- and p38a MAPKdependent manner (RT-qPCR), while it decreased release of IL-8 (ELISA), and it down-regulated additional pro-inflammatory cytokines (chemokine (C-X-C motif) ligand [CXCL]-1, CXCL2, CXCL6, colony-stimulating factor 2, IL-32). Collectively, specific TRPM5 modulators are unlikely to exert direct SG-related side effects, while safe TPPO analogues may induce beneficial moderate lipogenic and anti-inflammatory effects in dry skin dermatoses.
