Following an injury, the body recruits a mechanism to delimit and repair ti
ssue damage; this phenomenon is known as inflammation. Among the several di
fferent pathways that are activated during this process, which is necessary
for survival, activation of the coagulation pathway is a key feature. In f
act, clinical changes in blood fluidity have been closely related to ongoin
g inflammation. Recent evidence suggests that serine protease receptors mig
ht play a major role in the host defence mechanism at the interface between
coagulation and inflammation.
