Blockade1

  • Pre-existing antibodies may sustain platelet activation when estradiol treatment resumes

    Where this hypothesis actsStandardized donor platelets exposed to post-resumption plasma at fixed estradiol and PF4 concentrations

    What is proposedBlock FcγRIIa-dependent platelet activation

    With whatNot stated in the record

    HowFcγRIIa blockade in the plasma-transfer experiment; the blocking agent is not stated

    Possible resultExpected loss of antibody-mediated excess platelet activation
