A novel receptor cross-talk between the ATP receptor P2Y2 and formyl peptide receptors reactivates desensitized neutrophils to produce superoxide

Exp. Cell Res. 323(1) , 209-17, (2014)

Neutrophils express several G-protein coupled receptors (GPCRs) and they cross regulate each other. We described a novel cross-talk mechanism in neutrophils, by which signals generated by the receptor...

Integrin-mediated cell adhesion to extracellular matrix (ECM) is critical for normal epithelial cell survival; cells deprived of ECM contact rapidly undergo apoptotic cell death, termed anoikis. Recen...

Unique features of the okadaic acid activity class of tumor promoters.
