Definition

This essay delineates the pharmacological, physiological, pathological and therapeutical relevance of ► neuroactive steroids. These steroids are endogenous or synthetic compounds that can cross the ► blood-brain barrier and rapidly alter neuronal excitability via membrane receptors. We focus on neuroactive steroids that have specific binding sites on g-aminobutyric acid type-A (► GABAA) receptors which directly influence both synaptic and extrasynaptic transmission and indirectly alter many physiological processes including ► hypothalamic-pituitary-adrenal (HPA) axis function, inflammation, and myelin formation. Neuroactive steroid levels are modulated by stress, ovarian cycle, pregnancy, as well as numerous pharmacological agents. We summarize the sites of neu-roactive steroid actions, the systemic and molecular consequences of these actions, and the potential therapeutic relevance of their effects for neuropsychiatric disease.
