We found that activation of Jurkat T cells by a combination of phytohemagglutinin and phorbol 12-myristate 13-acetate led to a dramatic inhibition of thrombin receptor mRNA expression and to a concomitant loss of the thrombin response .
 ( protein: thrombin, None) , ( cell line: Jurkat T cells, None) , ( RNA: thrombin receptor mRNA, None) , ( protein: thrombin receptor, None) , ( protein: thrombin, None) , ( protein: phytohemagglutinin, None)
