Summary of Effects of APPA on Human Neutrophils Function
APPA is a synergistic combination of 2 synthetic anti-inflammatory molecules. APPA has shown efficacy in several animal models of osteoarthritis, decreasing pain and meniscal cartilage damage. Its efficacy is thought to be due to the effects of the constituent components on various levels of regulation of the transcription factor, NF-κB but as we show here also has effects upon other signalling pathways and neutrophil processes.
Neutrophils are the first line of defence against invading pathogens and are vital to fight infection. Their function in vivo and in vitro is regulated by the activities of a number of cytokines. These cells are potent producers of reactive oxidants species (ROS, activators of NF-κB) via an NADPH oxidase and many inflammatory functions are also regulated by NF-κB activation.
Summary:
It is clear that APPA via its two components, acts in an anti-inflammatory manner without affecting host defence mechanisms involved in bacterial killing. This work supports previous work observed here and in other laboratories on cell and animal models.
