Low‐Intensity Pulsed Ultrasound Alleviation of LPS‐Induced Depression‐Like Behavior via Microglial P2X4R Inhibition and BDNF/TrkB Pathway Activation

CNS Neuroscience &Therapeutics, Volume 32, Issue 2, February 2026.
LIPUS alleviates LPS‐induced depressive‐like behavior by suppressing microglial P2X4R in the hippocampus. P2X4R downregulation restores BDNF/TrkB signaling, thereby reducing microglial activation, pro‐inflammatory cytokine release, and neuronal apoptosis.

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.

Unravelling the intricate cooperativity of subunit gating in P2X2 ion channels

Scientific Reports, 2020
Ionotropic purinergic (P2X) receptors are trimeric channels that are activated by the binding of ATP. They are involved in multiple physiological functions, including synaptic transmission, pain and inflammation.

Activation of the P2Y2 receptor regulates bone cell function by enhancing ATP release [PDF]

, 2017
Bone cells constitutively release ATP into the extracellular environment where it acts locally via P2 receptors to regulate bone cell function. Whilst P2Y2 receptor stimulation regulates bone mineralisation, the functional effects of this receptor in ...

Optochemical modulation of corneal cold nerve terminal impulse activity with a photochromic ion channel blocker

British Journal of Pharmacology, Volume 183, Issue 3, Page 545-559, February 2026.
Background and Purpose The functional organization of corneal cold nerve endings, critical structures in maintaining the ocular surface, remains poorly understood. Here, the photoisomerizable small‐molecule diethylamine‐azobenzene‐quaternary ammonium (DENAQ) was used to photomodulate activity of cold‐sensing nerve terminals in control and chronic tear ...

Extracellular Adenosine Diphosphate Ribose Mobilizes Intracellular Ca2+ via Purinergic-Dependent Ca2+ Pathways in Rat Pulmonary Artery Smooth Muscle Cells

Cellular Physiology and Biochemistry, 2015
Background/Aims: Adenosine diphosphate ribose (ADPR), a product of β-NAD+ metabolism generated by the multifunctional enzyme CD38, is recognized as a novel signaling molecule. The catalytic site of CD38 orients extracellularly or intracellularly, capable

Astrocyte Regulation of Spinal Circuit Function

Journal of Neurochemistry, Volume 170, Issue 2, February 2026.
Spinal cord astrocytes exist as an additional component of the computational framework that governs both sensory perceptions and motor outputs (left). By integrating local synaptic activity together with signals that reflect whole‐body state (e.g., neuromodulators, immune signals, and vascular signals) into defined input states (Sn), astrocytes adapt ...

Glial cells in the heart: Implications for their roles in health and disease

The Journal of Physiology, Volume 604, Issue 4, Page 1531-1546, 15 February 2026.
Abstract figure legend Schematic representation of cardiac autonomic ganglia within epicardial fat pads (posterior heart surface shown), containing vagal postganglionic neuron cell bodies, associated fibres, and glia. These ganglia receive cholinergic input from vagal preganglionic neurons and adrenergic input from sympathetic postganglionic neurons ...

Raised tone reveals ATP as a sympathetic neurotransmitter in the porcine mesenteric arterial bed [PDF]

, 2014
The relative importance of ATP as a functional sympathetic neurotransmitter in blood vessels has been shown to be increased when the level of preexisting vascular tone or pressure is increased, in studies carried out in rat mesenteric arteries.
