What is the Origin of Progesterone Neurosteroids?

The concept emerged from the discovery that certain steroid hormones could be synthesized de novo in the brain, leading to the designation of "neurosteroids." This field of research clarified that progesterone's effects on mood and cognition are not solely due to peripheral hormone levels but also to the direct action of its metabolites in neural tissue.

What is the Mechanism of Progesterone Neurosteroids?

Progesterone neurosteroids primarily exert their function by acting as positive allosteric modulators of the GABA-A receptor, the brain's main inhibitory neurotransmitter system. By enhancing GABAergic signaling, these metabolites hyperpolarize the neuron, leading to a calming and anti-anxiety effect, effectively reducing neuronal excitability and promoting a state of tranquility.

Progesterone Neurosteroids

Meaning

A class of progesterone metabolites, such as allopregnanolone and pregnanolone, that are synthesized in the brain and peripheral nervous system and act locally as potent modulators of neuronal excitability and function. These neurosteroids are distinct from their systemic hormonal action and are known for their significant anxiolytic, sedative, and mood-stabilizing effects. They are crucial for mediating the calming effects associated with progesterone signaling in the central nervous system.
