(1) Background: Members of the TRPC3/TRPC6/TRPC7 subfamily of canonical transient receptor potential (TRP) channels share an amino acid similarity of more than 80% and can form heteromeric channel complexes. They are directly gated by diacylglycerols in a protein kinase C-independent

The requirement of calcium ion (Ca(2)(+)) entry for neutrophil NADPH oxidase (NOX2) regulation is clearly established. However, its role in the signaling pathway leading to NOX2 activation is still elusive. 1-oleoyl-2-acetyl-sn-glycerol (OAG) causes an increase in NOX2 activity and has

In this manuscript, involvement of PLD in fMLP-induced superoxide generation and degranulation were re-investigated using PLD(-/-) neutrophils, and the molecular mechanisms of these neutrophil functions were examined. Neither PLD1 nor PLD2 is involved in these fMLP-induced neutrophil functions. The results

Leukocyte transendothelial migration (TEM) is a tightly regulated, multistep process that is critical to the inflammatory response. A transient increase in endothelial cytosolic free calcium ion concentration (↑[Ca(2+)]i) is required for TEM. However, the mechanism by which endothelial ↑[Ca(2+)]i regulates

TRPC3, 6 and 7 channels constitute a subgroup of non-selective, calcium-permeable cation channels within the TRP superfamily that are activated by products of phospholipase C-mediated breakdown of phosphatidylinositol-4,5-bisphosphate (PIP(2)). A number of ion channels, including other members of the TRP
