Leonurine: A Multifaceted Bioactive Alkaloid—From Pharmacological Mechanisms to Clinical Translation: A Narrative Review

open access: yesHealth Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background Leonurine (LEO), a bioactive alkaloid derived from the Leonurus genus, exhibits diverse pharmacological activities including uterotonic, antioxidant, anti‐inflammatory, antiapoptotic, Antitumor, and vasoprotective effects. This review aims to provide a comprehensive overview of LEO's pharmacokinetics, pharmacological mechanisms ...

Structural basis of human zinc-activated channel (ZAC) signaling and modulation

open access: yesCell Discovery
Zinc (Zn2+) plays essential roles in a plethora of physiological processes, including key functions as a neuromodulator. The zinc-activated channel (ZAC) belongs to the Cys-loop receptor (CLR) superfamily of pentameric ligand-gated ion channels, which ...

The pyrogenic mediator prostaglandin E2 elicits warmth seeking via EP3 receptor‐expressing parabrachial neurons: a potential mechanism of chills

open access: yesThe Journal of Physiology, Volume 604, Issue 5, Page 2110-2130, 1 March 2026.
Abstract figure legend During infection, prostaglandin E2 (PGE2) is produced and elicits warmth‐seeking behaviour and involuntary febrile responses by acting on prostaglandin EP3 receptors (EP3Rs) in two distinct brain sites. PGE2 acting on EP3Rs on neurons in the external lateral part of the lateral parabrachial nucleus (LPBel) augments cold sensory ...

Reflex erection in the rat: reciprocal interplay between hemodynamic and somatic events

open access: yesBMC Urology, 2018
Background Penile erection is a complex reflex under spinal control and modulated by the brain. The hemodynamic events under autonomic control and the perineal muscles somatic activity are interconnected during the reflex erection at the spinal level ...

Distinct developmental dynamics of opposing persistent currents shape motoneuron firing during motor maturation of zebrafish

open access: yesThe Journal of Physiology, Volume 604, Issue 5, Page 2083-2109, 1 March 2026.
Abstract figure legend During the first few days of development, zebrafish acquire the ability to produce increasingly refined movements that rely progressively less on the activity of primary motoneurons. At the same time, primary motoneurons undergo functional maturation, becoming increasingly capable of repetitive firing.

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...
