Abstract
Fluvoxamine, a usual SSRI antidepressant, has agonistic activity on
Sigma-1 receptors in ER and inhibits IRE1, an important trigger of
cytokine production; Sigma-1 receptor is a target of SARS-COV-2 protein
Nsp6 and may start the cytokine storm. The available Sigma-1 agonists
may represent important alternatives to treat the cytokine storm and
save lives.
