May 2016 in “Cell Host & Microbe” In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.
September 1997 in “JEADV. Journal of the European Academy of Dermatology and Venereology/Journal of the European Academy of Dermatology and Venereology” Blocking IL-1 could help treat some hair loss conditions; alopecia affects liver detox systems; spironolactone is better than finasteride for female hair growth; focusing on the catagen hair phase could lead to new alopecia treatments.
September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology” This study reports that the loss of Langerhans cells in lichen planopilaris scars may be linked to the downregulation of ITG αvβ6, which is not seen in other scar formation diseases.
