P2X7 Receptor Triggers Lysosomal Leakage Through Calcium Mobilization in a Mechanism Dependent on Pannexin-1 Hemichannels

Frontiers in Immunology, 2022
The P2X7 receptor is a critical purinergic receptor in immune cells. Its activation was associated with cathepsin release into macrophage cytosol, suggesting its involvement in lysosomal membrane permeabilization (LMP) and leakage.

Astrocytes as central integrators of neural circuit function: Mechanisms and dysregulation in neuropsychiatric disorders

Clinical and Translational Discovery, Volume 6, Issue 2, April 2026.
1. Astrocytes are central integrators of neural circuit function through tripartite synapse modulation and neurovascular coupling. 2. Dysregulation of glutamate/GABA homeostasis and neuroinflammation represents shared mechanisms across diverse neuropsychiatric disorders. 3.

Ionotropic purinergic receptor 7 (P2X7) channel structure and pharmacology provides insight regarding non-nucleotide agonism

Channels
P2X7 is a member of the Ionotropic Purinergic Receptor (P2X) family. The P2X family of receptors is composed of seven (P2X1–7), ligand-gated, nonselective cation channels. Changes in P2X expression have been reported in multiple disease models. P2Xs have

Paroxetine suppresses recombinant human P2X7 responses [PDF]

Purinergic Signalling, 2015
P2X7 receptor (P2X7) activity may link inflammation to depressive disorders. Genetic variants of human P2X7 have been linked with major depression and bipolar disorders, and the P2X7 knockout mouse has been shown to exhibit anti-depressive-like behaviour.

Targeting inflammation in cardiometabolic disease: Icosapent ethyl modulates monocyte‐derived macrophages isolated from patients with cardiovascular disease with or without type 2 diabetes

Diabetic Medicine, Volume 43, Issue 4, April 2026.
Abstract Aims Despite intensive lipid‐lowering therapy, individuals with atherosclerotic cardiovascular disease (ASCVD) exhibit residual inflammatory risk, which drives recurrent cardiovascular events. This risk is amplified in type 2 diabetes mellitus (T2DM), where a pro‐inflammatory milieu accelerates atherogenesis. Monocyte‐derived macrophages (MDMs)

Microglial HVCN1 Deficiency Improves Movement and Survival of SOD1G93A ALS Mice by Enhancing Microglial Migration and Neuroprotection

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Hydrogen voltage gated channel 1 (HVCN1) is upregulated in microglia of both ALS patients and its mouse model. HVCN1 deficiency enhances microglial migration via suppressing Akt signaling, promotes neurotrophic capacity and motor function, and prolongs survival of the SOD1G93A ALS mice. This study identifies HVCN1 as a novel, promising druggable target

Different localization of P2X4 and P2X7 receptors in native mouse lung - lack of evidence for a direct P2X4-P2X7 receptor interaction

Frontiers in Immunology
IntroductionP2X receptors are a family of homo- and heterotrimeric cation channels gated by extracellular ATP. The P2X4 and P2X7 subunits show overlapping expression patterns and have been involved in similar physiological processes, such as pain and ...

AMPK-dependent and independent actions of P2X7 in regulation of mitochondrial and lysosomal functions in microglia

Cell Communication and Signaling, 2018
Background P2X7 is ubiquitously expressed in myeloid cells and regulates the pathophysiology of inflammatory diseases. Since mitochondrial function in microglia is highly associated with microglial functions in controlling neuronal plasticity and brain ...

Electromagnetic field treatment increases purinergic receptor P2X7 expression and activates its downstream Akt/GSK3β/β-catenin axis in mesenchymal stem cells under osteogenic induction

Stem Cell Research & Therapy, 2019
Background Imbalance in bone formation and resorption is a crucial component of the pathological process leading to osteoporosis. Electromagnetic fields (EMFs) have been reported to be beneficial to osteogenesis, although the exact mechanism has not been
