VlPAG/DRN Microglia Drive Neuropathic Pain‐Induced Depression via a Defined Neuroimmune Axis
Peripheral nerve injury (SNI) induces neuropathic pain, activates midbrain microglia, and triggers an NLRP3–IL‐1β–dependent inflammatory cascade. IL‐1β signals through IL‐1R1 on vlPAG/DRN VGLUT2+ neurons (vlPAG/DRNGlu), inducing hyperexcitability and driving the vlPAG/DRNGlu→BNSTGABA circuit to produce the affective component of neuropathic pain ...

Hypoxia induces purinergic receptor signaling to disrupt endothelial barrier function
Blood-brain-barrier permeability is regulated by endothelial junctional proteins and is vital in limiting access to and from the blood to the CNS. When stressed, several cells, including endothelial cells, can release nucleotides like ATP and ADP that ...

Impact of sleep insufficiency and recovery on cancer development
Abstract Sleep plays a critical role in overall health, and modern lifestyles, such as shift work and late‐night activities, can significantly impact sleep condition. Insufficient sleep has been associated with various adverse health outcomes, including an increased risk of tumor development.

The role of purinergic signaling in microglial responses
Microglia, the primary immune cells in the central nervous system (CNS), are key to the maintenance of homeostasis in the brain parenchyma. In the intact brain, microglia continuously survey the microenvironment with ramified processes.

The potential for biased signalling in the P2Y receptor family of GPCRs
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

TMEM16A channel signalling microdomains in the regulation of vascular function
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

CX3CR1 Modulates Migration of Resident Microglia Towards Cortical Laser‐Induced Lesions
CX3CR1 deficiency promotes microglial migration toward CNS injury. Proteomic profiling reveals altered RHO‐mediated cytoskeletal signaling, while in vivo two‐photon imaging demonstrates increased process extension, velocity, and accumulation of Cx3cr1‐deficient microglia at lesion sites. ABSTRACT Microglia are innate immune cells of the central nervous

Obesity has become one of the major public health problems in both the developing and developed countries. Recent studies have suggested that the purinergic signalling is involved in obesity-associated end-organ damage through purine P1 and P2 receptors.

Metabolic Regulation of Macrophages in Health and Disease
Extracellular metabolites drive metabolic rewiring of glucose, lipid, and amino acid pathways in macrophages, steering their polarization toward pro‐ or anti‐inflammatory phenotypes and shaping a wide range of disease processes. Macrophages from different tissues display distinct metabolic signatures, and therapeutic strategies that target these ...
