Uteroglobin, a steroid-dependent, small molecular weight (15K) protein in the rabbit, inhibited thrombin-induced aggregation of both rabbit and human gel-filtered platelets (GFP). GFP aggregation by arachidonic acid was not affected by uteroglobin. There were no effects of uteroglobin on thrombin-induced clotting of plasma or purified fibrinogen, or inhibition of thrombin by antithrombin III. Additionally, preliminary results suggest that uteroglobin does not interfere with binding of thrombin to platelets. We suggest that inhibition of platelet aggregation by uteroglobin may function in preventing thrombosis and ensuring free flow of blood through the microvasculature of the uterus and the placenta and may induce some of the antimotility effects of progesterone on the uterus.

Uteroglobin/Clara cell 10-kDa protein (UG/CC10) is a hormonally regulated small secretory protein that has a variety of in vitro and in vivo pharmacological effects. These include a potent anti-inflammatory activity and inhibitory effects on neutrophil migration, thrombin-induced platelet aggregation, in vitro chemoinvasion, as well as "tumor suppressor"-like effects and other properties. Several mechanisms of action have been proposed for these effects. Pharmacological properties suggest that UG itself or substances derived from it may be used as experimental drugs for several indications. The group of oligopeptides collectively known as "antiflammins" (AFs) were originally described in 1988. Their design was derived from the region of highest sequence similarity between UG and another group of proteins with anti-inflammatory properties, the lipocortins or annexins. Nanomolar concentrations of these peptides can reproduce several of the pharmacological activities of UG, including its in vivo anti-inflammatory effects and inhibition of platelet aggregation. The AFs have been safely and effectively used to suppress inflammation and fibrosis in several animal models. Progress in clarifying the mechanism of action of the AFs may facilitate the structure-based design of a novel class of potent anti-inflammatory, antichemotactic drugs.
