General information

Estradiol is a steroid hormone essential for the development of female secondary sexual characteristics and female fertility. It is produced in ovaries. Estradiol modulates metabolism and increases blood coagulability. It has an impact on inflammatory and other immune processes (NCIt).

17β‐estradiol reduces SARS‐CoV‐2 infection in vitro
TMPRSS2 Small molecule In vitro
Vero E6 cells 2.13

In Vero E6 cells SARS-CoV-2 infection lead to increase in ACE2 and TMPRSS2 expression. Pre- or post-infection treatment of cells with estradiol decreased the viral load. The decrease might have been facilitated by estradiol-induced downregulation of TMPRSS2, which is a SARS-CoV-2 viral entry factor.
