Description

Application

Dexamethasone has been used as a component of osteogenic differentiation medium. It has also been used to study apoptosis, cell signaling pathways and gene expression.

Actions biochimiques/physiologiques

Agent anti-inflammatoire du type glucocorticoïde. Régule la survie, la croissance et la différenciation des lymphocytes T. Inhibe l′induction de l′oxyde nitrique synthase.

Dexamethasone has immunosuppressant and antiemetic properties. It is used to treat postoperative nausea and vomiting (PONV) and chemotherapy-induced nausea and vomiting (CINV). Dexamethasone plays an important role in cardiac transplant, sepsis, cancer and other pathologic disorders. It elevates the level of heat shock proteins. It is an anti-inflammatory glucocorticoid with a range of effects on cell survival, cell signaling and gene expression.
