TMPRSS2 is dispensable for development and homeostasis (Kim et al., 2006) and thus constitutes an attractive drug target. In this context, it is noteworthy that the serine protease inhibitor Camostat mesylate, which blocks TMPRSS2 activity (Kawase et al., 2012; Zhou et al., 2015), has been approved in Japan for human use, but for an unrelated indication
