15d-Prostaglandin J2 inhibits noncanonical inflammasome response to ameliorate endotoxin shock.

15d-prostaglandin J2 protects brain from ischemia-reperfusion injury.

OBJECTIVE Brain expresses abundant lipocalin-type prostaglandin (PG) D2 (PGD2) synthase but the role of PGD2 and its metabolite, 15-deoxy-Delta(12,14) PGJ2 (15d-PGJ2) in brain protection is unclear. The aim of this study is to assess the effect of 15d-PGJ2 on neuroprotection. METHODS AND RESULTS Adenoviral transfer of cyclooxygenase-1 (Adv-COX-1) was used to amplify the production of 15d-PGJ2...

15d-prostaglandin J2 inhibits inflammatory hypernociception: involvement of peripheral opioid receptor.

The 15-deoxy-Delta(12,14)-prostaglandin J(2) (15d-PGJ(2)) is an endogenous ligand of peroxisome proliferator-activated receptors gamma (PPAR-gamma) and is now recognized as a potent anti-inflammatory mediator. However, information regarding the influence of 15d-PGJ(2) on inflammatory pain is still unknown. In this study, we evaluated the effect of 15d-PGJ(2) upon inflammatory hypernociception a...

Effects of 15-Deoxy-Δ12,14-Prostaglandin J2 (15d-PGJ2) and Rosiglitazone on Human Vδ2+ T Cells

BACKGROUND Thiazolidinediones (TZD) class of drugs, and 15-deoxy-D12,14-prostaglandin J2 (15d-PGJ2) are immune regulators predicted to modulate human autoimmune disease. Their effects on gammadelta T cells, which are involved in animal model and human and animal autoimmune diseases, are unknown. METHODOLOGY/PRINCIPAL FINDINGS We characterized the activity of rosiglitazone (from the TZD class ...

SnapShot: The Noncanonical Inflammasome

This SnapShot depicts how the noncanonical inflammasome pathway is initiated and activated, as well as its effector mechanism in triggering pyroptosis and immune defenses.
