Platelet-rich fibrin (PRF) has shown clinical success in pain reduction. By what mechanism does the PRF regulate the pain pathway?

Best Regards,
The way how platelet lysates, in general, and PRF, in particular, can reduce pain and inflammation is not fully understood. A limited number of publications have highlighted the role of TGF-b and HGF, released by platelets, in inhibiting some inflammatory pathway leading to reduced production of inflammatory cytokines like TNF-alpha. More research is needed to understand this anti-inflammatory/analgesic role especially as it is likely to vary depending upon characteristics of the platelet materials and the tissues. Still some way to go... Best, Thierry
I can only hypothyse the following: Previous studies have associated IL-1B, TNF-α, IL-6 and IL-8 with pain. The release of IL-4, an anti-inflammatory cytokines found in PRF, modulates inflammation and pain by inhibiting MMPs and neutralizing transduction pathways from IL-1B, TNF-α and prostaglandins.
In the cited study PRF 110 relates to Pain Reform Formula No.110 and not to Platelets...
