TBXT and systemic lupus erythematosus: Researchers have reported that estrogen increases T‐cell calcineurin expression in patients with SLE (Rider et al., 1998), androgens decrease expression of the pathogenic FcgammaRIIB2 gene in Graves' disease (Estienne et al., 2002), progesterone induces autoimmune thyroiditis in rats (Ansar Ahmed et al., 1983), and prolactin increases SLE activity in mice (McMurray et al., 1991).
