Platelet Activating Factor (PAF) and its associated receptor, the PAF Receptor (PAFR), are important mediators of intercellular communication during an immune response. Once a physiological stimulus triggers an inflammatory response, epithelial, endothelial and immune cells synthesize and release PAF. PAF mediates the recruitment of immune cells, platelets, angiogenesis, expression of various genes, and increased PAF biosynthesis (Brown, 2006; Han, 2006; Whatley, 1988; Axelrod, 1988). In this study, we utilized HaCaT cells and a well characterized KB cell line derived from nasopharyngeal cells, which do not natively express the PAFR. KB cells had previously been transfected with a PAF receptor (KBP) …
