GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Astrocytes: The Unsung Architects of Synaptic Integration and Their Role in Brain Health and Disease

Biomolecules
Astrocytes, long viewed as passive support cells, are now recognized as dynamic regulators of synaptic function. This mini review summarizes recent findings revealing that astrocyte leaflets, thin peripheral processes of astrocyte, form gap junction ...

P2X1 and P2X5 subunits form the functional P2X receptor in mouse cortical astrocytes [PDF]

, 2008
ATP plays an important role in signal transduction between neuronal and glial circuits and within glial networks. Here we describe currents activated by ATP in astrocytes acutely isolated from cortical brain slices by non-enzymatic mechanical ...

Microglial Deubiquitinase OTUD7B Stabilizes STAT3 to Promote Neuroinflammation and Cognitive Decline in Alzheimer's Disease

Advanced Science, EarlyView.
. ABSTRACT Neuroinflammation driven by microglial activation is a defining feature of Alzheimer's disease (AD), yet the molecular mechanisms sustaining this proinflammatory state remain unclear. Here, we identify the deubiquitinase OTUD7B as a critical regulator of microglial activation and AD pathology.

Role of astrocytes in the pathogenesis of perinatal brain injury

Molecular Medicine
Astrocytes, the most abundant glial cells in the central nervous system (CNS), play critical roles in blood–brain barrier (BBB) maintenance, synaptogenesis, neurotransmission, and metabolic regulation.

Astrocytic LMP2 Coordinates NF‐κB and TGF‐β1/Smad3 Signaling to Drive Neuroinflammation after Cerebral Ischemia/Reperfusion

Advanced Science, EarlyView.
ABSTRACT Astrocyte reactivity critically shapes neuroinflammatory outcomes after ischemic stroke, yet the upstream regulators governing astrocyte state transitions remain incompletely defined. Here, we identify the immunoproteasome subunit low molecular weight protein 2 (LMP2) as an important modulator of astrocyte functional remodeling following ...

Cortical astrocyte histamine-1-receptors regulate intracellular calcium and extracellular adenosine dynamics across sleep and wake.

PLoS Biology
Classical neuromodulators regulate arousal states, spanning deep sleep to vigilant wakefulness, primarily by activating cortical neurons. However, cortical astrocytes also express neuromodulatory G-protein-coupled receptors (GPCRs).

Astrocyte signaling controls spike timing-dependent depression at neocortical synapses

, 2012
Endocannabinoid mediated spike timing-dependent depression (t-LTD) is crucially involved in the development of the sensory neocortex. t-LTD at excitatory synapses in the developing rat barrel cortex requires cannabinoid CB(1) receptor (CB(1)R) activation,

Studies on the role of Coronin 1 and the actin cytoskeleton in T cell signaling and survival [PDF]

, 2009
Calcium ions (Ca2+) function as universal second messengers in most if not all eukaryotic cells, including the cells of the immunesystem. Ca2+ signals are required for the proper activation of lymphocytes, such as T-lymphocytes, their proliferation ...
