Activation of α7 nicotinic acetylcholine receptor by nicotine selectively up-regulates cyclooxygenase-2 and prostaglandin E₂ in rat microglial cultures

Journal of Neuroinflammation, 2005
Background Nicotinic acetylcholine (Ach) receptors are ligand-gated pentameric ion channels whose main function is to transmit signals for the neurotransmitter Ach in peripheral and central nervous system.

Functional Polarization of Liver Macrophages by Glyco Gold Nanoparticles

Advanced Science, EarlyView.
Macrophages play a critical role in several pathophysiological diseases by being involved in the activation of adaptive and innate immune responses. The repolarization of macrophages using gold nanoparticles functionalized with glycans for a more selective targeting toward a restorative phenotype leads to an amelioration of the events.

Regional distribution of the prostaglandin E2 receptor EP1 in the rat brain: accumulation in Purkinje cells of the cerebellum [PDF]

Journal of Molecular Neuroscience 27(3): 303-310 (2005), 2007
Prostaglandin E2 (PGE2), is a major prostanoid produced by the activity of cyclooxygenases (COX) in response to various physiological and pathological stimuli. PGE2 exerts its effects by activating four specific E-type prostanoid receptors (EP1, EP2, EP3, and EP4).

YC‐4‐3, a Novel Glycogen Synthase Kinase 3β Inhibitor, Alleviates the Endoplasmic Reticulum Stress of Macrophages in Primary Immune Thrombocytopenia

Advanced Science, EarlyView.
A patented GSK‐3β inhibitor (GSK‐3βi), new benzothiazepinone compounds (BTZs), YC‐4‐3, can modulate the inflammatory status of macrophages in primary immune thrombocytopenia (ITP), and improve the thrombocytopenia in murine ITP models by directly interacting with endoplasmic reticulum (ER) stress response.

Wide therapeutic time window for nimesulide neuroprotection in a model of transient focal cerebral ischemia in the rat [PDF]

Brain Research 1007(1-2): 98-108 (2004), 2007
Results from several studies indicate that cyclooxygenase-2 (COX-2) is involved in ischemic brain injury. The purpose of this study was to evaluate the neuroprotective effects of the selective COX-2 inhibitor nimesulide on cerebral infarction and neurological deficits in a standardized model of transient focal cerebral ischemia in rats.

mPGES-1-Derived PGE2 Contributes to Indoxyl Sulfate-Induced Mesangial Cell Proliferation

Cellular Physiology and Biochemistry, 2017
Background/Aims: We previously reported that indoxyl sulfate (IS) could cause mesangial cell (MC) proliferation via a cyclooxygenase (COX)-2-dependent mechanism.

Nuclear Translocation of S100A9 Triggers Senescence of Human Amnion Fibroblasts by De‐Repressing LINE1 Via Heterochromatin Erosion at Parturition

Advanced Science, EarlyView.
This study shows that the classical secretory protein S100 calcium‐binding protein A9 (S100A9) can translocate to the nucleus upon de‐phosphorylation at Thr 113 in human amnion fibroblasts at parturition, where S100A9 induces heterochromatin erosion through segregation of the heterochromatin maintenance protein, resulting inLong Interspersed Nuclear ...

Post-ischaemic treatment with the cyclooxygenase-2 inhibitor nimesulide reduces blood-brain barrier disruption and leukocyte infiltration following transient focal cerebral ischaemia in rats [PDF]

Journal of Neurochemistry 100(4): 1108-1120 (2007), 2007
Several studies suggest that cyclooxygenase (COX)-2 plays a pivotal role in the progression of ischaemic brain damage. In the present study, we investigated the effects of selective inhibition of COX-2 with nimesulide (12 mg/kg) and selective inhibition of COX-1 with valeryl salicylate (VAS, 12-120 mg/kg) on prostaglandin E2 (PGE2) levels ...

Microvascular COX-2/mPGES-1/EP-4 axis in human abdominal aortic aneurysm

Journal of Lipid Research, 2013
We investigated the prostaglandin (PG)E2 pathway in human abdominal aortic aneurysm (AAA) and its relationship with hypervascularization. We analyzed samples from patients undergoing AAA repair in comparison with those from healthy multiorgan donors ...
