Kallikrein-6-Regulated Pathways Shed Light on New Potential Targets in Varicella Zoster Virus Infection.

Varicella zoster virus, the worldwide infectious human virus responsible for acute varicella and chickenpox, commonly spreads from exposure through contact with a skin lesion or airborne respiratory droplets. Keratinocytes, major targets and source of transmission of the virus present in the skin, represent an ideal choice of cell to stop early virus progression. In their recent study, Tommasi et al. show regulatory mechanisms of cytokeratin 10 through the protease kallikrein-6 as a suitable and druggable pathway to reduce varicella zoster virus dissemination.
