thromboxane-b2 and African-Swine-Fever

Changes in the production of proaggregatory (thromboxane A2 and prostaglandin E2) and antiaggregatory (prostacyclin) prostaglandins by blood platelets, macrophages and endothelial cells during acute African swine fever caused by both a highly virulent virus and a less virulent virus were studied. No impairment in thromboxane A2 release by either platelets or macrophages could be detected but prostacyclin production by the endothelium was impaired. There was also a significant increase in prostaglandin E2 release by macrophages at the time when thrombocytopenia was most marked. However, the early event that causes primary aggregation remains obscure.
