Differential effects of endotoxin and fibrinogen degradation products (FDPS) on liver synthesis of fibrinogen and albumin: evidence for the involvement of a novel monokine in the stimulation of fibrinogen synthesis induced by FDPS
article
1. Administration of endotoxin or fibrinogen degradation products (FDPs) in rats increase nbrinogen synthesis comparable to that found during the acute phase response. 2. An increased fibrinogen synthesis is also found in co-cultures of hepatocytes with peripheral blood mononuclear cells upon administration of endotoxin or FDPs, but not in primary cultures of hepatocytes alone. 3.However, the increased synthesis of nbrinogen by FDPs is not accompanied by a decreased albumin synthesis, as in the case of stimulated fibrinogen synthesis induced by endotoxin in vivo and in co-cultures of hepatocytes with peripheral blood mononuclear cells, or induced by monocytic products in vivo and in primary cultures of hepatocytes alone. 4. Since IL-1 and/or IL-6 could not be accounted for the stimulation of nbrinogen synthesis without a decreased albumin synthesis, a novel monokine produced by mononuclear cells upon FDP administration might be involved.
