The aim of this work was to study the effect of various anti-inflammatory drugs on PGE2 synthesis in cultured bovine corneal endothelial cells (BCECs) stimulated with calcium ionophore A23187 or lipopolysaccharide (LPS) of Salmonella typhimurium. NSAIDs were more potent in inhibiting LPS-stimulated PGE2 synthesis. Diclofenac was more potent than indomethacin, although both drugs showed a 98% maximal inhibitory effect. Dexamethasone inhibited 80% of the A23187-stimulated PGE2 synthesis and only 53% of the LPS-stimulated PGE2 synthesis. Prednisolone did not show an inhibitory effect. The results demonstrate the inhibitory effect of NSAIDs and show differences between the activity of glucocorticoids on PGE2 synthesis in BCECs. Prednisolone could not inhibit PGE2 synthesis in these cells in our experimental conditions.

Introduction: The spectrum of eosinophil functions has expanded from fighting helminths to multiple novel roles in malignancy, infection, cancer, and metabolism. In asthma, glucocorticoids, prostaglandins (PG), and cysteinyl-leukotrienes (LT) regulate eosinophil biology through separate signaling pathways. Here we've evaluated the complex interplay between Dexa, PGE2, and CysLTs in eosinopoiesis and eosinophil biology in an allergic asthma model.

The inhibition of human microsomal prostaglandin E (PGE) synthase-1 (mPGES-1) is a promising therapeutic modality for developing next-generation anti-inflammatory medications. In this study, we present novel 2-phenylbenzothiazole derivatives featuring heteroaryl sulfonamide end-capping substructures as inhibitors of human mPGES-1, with IC values in the range of 0.72-3.

This study aimed to elucidate the pivotal enzymes and molecular mechanisms underlying PGE synthesis induced by central Ang II (angiotensin II) and its implications in the heightened oxidative stress and sympathetic outflow in hypertension.
Methods And Results: RVLM microinjections of PGE and Tempol were administered in Wistar-Kyoto rats.

Prostaglandin E2 (PGE2) plays a crucial role in inflammation. Non-steroidal anti-inflammatory medications are commonly utilized to alleviate pain and address inflammation by blocking the production of PGE2 and cyclooxygenase (COX). However, selective inhibition of COX can easily lead to a series of risks for cardiovascular diseases.

Inflammation-proliferation transition plays a key role in the successful healing of a common burn type, second-degree burn. Gynura procumbens in vitro adventitious root nanohydrogel is currently being studied for its immunomodulatory to improve reparative environment. Root production and nanohydrogel preparation was done respectively by in vitro propagation and emulsion/ solvent diffusion with carbomer as a polymer.
