Cellular and molecular mechanisms of neurosteroids in various parts of the central nervous system of rats (part I)

Якутский медицинский журнал
Neuroactive steroids are a class of endogenous steroids synthesized in the nervous tissue and / or capable of having a modulating effect on its functional activity in the brain.

Neuronal and ion channel mechanisms of noxious heat sensing in mammals: A puzzle of sensory physiology and pharmacology

British Journal of Pharmacology, EarlyView.
Transient receptor potential vanilloid 1 (TRPV1) was the first noxious heat‐sensitive channel discovered. In rodents, its role is robust in the heat response of the cell body of polymodal nociceptors, but surprisingly small in that of the peripheral terminals in the skin.

Neurosteroids and GABA-A receptor function

Frontiers in Endocrinology, 2011
Neurosteroids represent a class of endogenous steroids that are synthesized in the brain, the adrenals and the gonads and have potent and selective effects on the GABAA-receptor.

Disease-associated mutations in the human TRPM3 render the channel overactive via two distinct mechanisms

eLife, 2020
Transient Receptor Potential Melastatin 3 (TRPM3) is a Ca2+ permeable non-selective cation channel activated by heat and chemical agonists such as pregnenolone sulfate and CIM0216.

TRPM3 regulates fear memory encoding and seizure susceptibility in the lateral amygdala

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose TRPM3 is best known for its role as a peripheral sensor of pain and heat. Recent studies reporting gain‐of‐function TRPM3 mutations in patients with neurodevelopmental and epilepsy‐associated disorders suggest a previously unrecognized role of this channel in the brain.

Steady‐state activation and modulation of the synaptic‐type α1β2γ2L GABAA receptor by combinations of physiological and clinical ligands

Physiological Reports, 2019
The synaptic α1β2γ2 GABAA receptor is activated phasically by presynaptically released GABA. The receptor is considered to be inactive between synaptic events when exposed to ambient GABA because of its low resting affinity to the transmitter.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Potentiation effects of the positive allosteric modulator PTC‐174 on NMDA receptors in neonatal male rat substantia nigra dopaminergic neurons

British Journal of Pharmacology, Volume 183, Issue 21, Page 6481-6500, November 2026.
Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.

Divergent mechanisms of steroid inhibition in the human ρ1 GABAA receptor

Nature Communications
ρ-type γ-aminobutyric acid-A (GABAA) receptors are widely distributed in the retina and brain, and are potential drug targets for the treatment of visual, sleep and cognitive disorders.

The Underlying Mechanism of Modulation of Transient Receptor Potential Melastatin 3 by protons

Frontiers in Pharmacology, 2021
Transient receptor potential melastatin 3 channel (TRPM3) is a calcium-permeable nonselective cation channel that plays an important role in modulating glucose homeostasis in the pancreatic beta cells.
