Lutein inhibits IL‑6 expression by inducing PPAR‑γ activation and SOCS3 expression in cerulein‑stimulated pancreatic acinar cells.

Acute pancreatitis is a severe inflammatory disease of the pancreas. In experimental acute pancreatitis, cerulein induces the expression of interleukin‑6 (IL‑6) by activating Janus kinase (JAK) 2/signal transducer and activator of transcription (STAT) 3 in pancreatic acinar cells. Ligands of peroxisome proliferator activated receptor‑γ (PPAR‑γ) and suppressor of cytokine signaling (SOCS) 3 inhibit IL‑6 expression by suppressing JAK2/STAT3 in cerulein‑stimulated pancreatic acinar AR42J cells.

Docosahexaenoic Acid Inhibits Cytokine Expression by Reducing Reactive Oxygen Species in Pancreatic Stellate Cells.

Pancreatic stellate cells (PSCs) are activated by inflammatory stimuli, such as TNF-α or viral infection. Activated PSCs play a crucial role in the development of chronic pancreatitis. Polyinosinic-polycytidylic acid (poly (I:C)) is structurally similar to double-stranded RNA and mimics viral infection.

HSP90beta interacts with Rac1 to activate NADPH oxidase in Helicobacter pylori-infected gastric epithelial cells.

Reactive oxygen species (ROS) are involved in the pathogenesis of Helicobacter pylori (H. pylori)-induced gastric disorders including inflammation. NADPH oxidase has been considered as a major source of ROS in phagocytic and non-phagocytic cells.
