摘要

In addition to their roles in haemostasis and thrombosis, platelets are important players in several other processes and their role in inflammation is also recognized (Weyrich & Zimmerman, 2004). Platelets express transcription factors involved in non-genomic functions, including the positive and negative regulation of platelet activation. Recent studies (Malaver et al, 2009; Spinelli et al, 2010) have proposed that inhibition of platelet nuclear factor kB (NFkB) leads to the modulation of platelet function and that NFkB may be a novel mediator of platelet response. NFkB is the major transcription factor that regulates the genes involved in immune responses. The thrombin versus "immune" stimulation of platelets and their subsequent differential effects on the activation of signalling pathways as well as on specific protein-protein interactions and alpha granule release have recently been partly examined (Rex et al, 2009). Platelets express the Toll-like receptor (TLR) 2, 4, and 9 molecules (Andonegui et al, 2005; Cognasse et al, 2005).
