American Society of Hematology

The American Society of Hematology (ASH) leads the world in promoting and supporting clinical and scientific hematology research through its many innovative award programs, meetings, publications, and advocacy efforts.


Blood is the official journal of the American Society of Hematology and the most cited peer-reviewed publication in the field. It is published weekly every Thursday, except for the last week in December, in addition to the ASH Annual Meeting Abstracts issue in November.

    The relationship between hemostasis and inflammation has emerged as a major area of investigation in recent years. The laboratory of Charles Esmon, in which the present work was performed, has played a major role in developing this area of study by unraveling mechanisms by which the serine protease, activated protein C (APC), functions.

    The alternative pathway of complement (APC) is in a state of continuous, low-grade activation, and host erythrocytes are normally protected against complement-mediated injury by two glycosyl phosphatidylinositol (GPI)-anchored membrane proteins. Decay accelerating factor (DAF, CD55) inhibits the formation and stability of the APC C3 and C5 amplification convertases and membrane inhibitor of reactive lysis (MIRL, CD59) block the assembly of the cytolytic membrane attack complex (MAC).

    Haploidentical transplantation could just as easily be called haplounidentical transplantation, because recipient and donor are matched at HLA loci on one chromosome 6 (haploidentical) but not on the other (haplounidentical).

  • Use of Direct Oral Anticoagulants in Patients on Hemodialysis

    Dr. Moll reviews a study that looks at the use of direct oral anticoagulants, specifically apixaban, in patients on hemodyalisis.
