What is the Origin of Neurosteroid Allopregnanolone?

The term combines "neurosteroid," indicating a steroid synthesized in the nervous system, with "allopregnanolone," its chemical name derived from its structural relationship to progesterone. Its discovery highlighted a novel mechanism of steroid action within the brain, independent of traditional nuclear hormone receptors.

What is the Mechanism of Neurosteroid Allopregnanolone?

Allopregnanolone functions by binding to a specific site on the GABA-A receptor complex, enhancing the inhibitory effects of GABA. This action increases the influx of chloride ions into the neuron, hyperpolarizing the cell and making it less likely to fire an action potential. This dampening of neuronal excitability is the fundamental mechanism behind its calming effects, providing a crucial counter-regulatory balance to the excitatory neurotransmitter systems.

Neurosteroid Allopregnanolone

Meaning

Allopregnanolone is a potent, naturally occurring neurosteroid metabolite of the hormone progesterone, synthesized both in the adrenal glands and directly within the central nervous system. This molecule is a positive allosteric modulator of the GABA-A receptor, the brain’s primary inhibitory neurotransmitter system, exerting powerful anxiolytic, sedative, and anticonvulsant effects. Its levels are closely linked to mood stability, stress resilience, and the regulation of the sleep cycle.
