Microvesicle particles (MVPs) are subcellular particles that could be involved in inter-cellular communication because they carry various bioactive substances including cytokines. Previous studies from our lab has shown that that the lipid mediator Platelet-activating Factor (1-alkyl-2-acetyl-glycerophosphocholine; PAF) and ultraviolet B radiation (UVB) enhances the release of MVP in various cell types like primary keratinocytes, epithelial cell lines, and murine skin. We hypothesized that there may be synergistic increases in MVP release after combination of treatment of keratinocytes with UVB and PAF agonist (CPAF)/phorbol ester (PMA). The combination treatment significantly increases MVP and cytokine release at 4 to 8 hours time …
