ASH Annual Meeting and Exposition

Special Scientific Symposia

The Special Scientific Symposia feature presentations that cover the latest scientific developments that cut across many sub-disciplines of hematology and appeal to a wide audience.

Unless otherwise noted, all sessions will take place in person and stream simultaneously on the virtual platform. Session recordings will be available on demand on the virtual platform.

Cellular Heterogeneity and Relationship to Clinical Outcomes

Cellular therapies are quite heterogeneous by nature, but regulatory and industry groups have focused on defining particular products with "critical product attributes" while minimizing heterogeneity. This session will highlight the potential benefits of cellular heterogeneity, in both immune effector cells and within post-transplant cell populations.

Interphase of Complement and Coagulation

The complement system and coagulation pathways are the main pillars of immunity and hemostasis respectively that undergo significant activation with injury. While appearing distinct, it is recognized that significant crosstalk exists between the two systems and recently established molecular mechanisms provide insights into a wide variety of disorders. This session will focus on new molecular links identified in complement activation in specific and highly relevant clinical disorders.

Interrogating the Impact of the Intestinal Microbiome on Transplant and Cellular Therapies

Fundamental advances have been achieved in the treatment of patients with hematologic malignancies through transplant and cellular therapy (TCT), including hematopoietic cell transplant and chimeric antigen receptor (CAR) T cell therapy. However, the therapies have limitations, such as relapses and toxicity. TCT outcomes have been associated with the intestinal microbiome. This session will focus on the intestinal microbiome in relation to TCT, from correlative research to interventional studies.

Newly Discovered Functions of Megakaryocytes and Platelets

This session will reveal new mechanisms of diseases related to platelet formation and function. Specifically, it will address glycosylation in megakaryocytes (Mks)/platelet functions and diseases; and highlight new insights in thromboinflammation, functions, and diseases of Mks and platelets.

Placing the Brakes on Accelerated Aging

Hematologic disorders disproportionately affect older adults; despite this, our understanding of the implications of age on the pathogenesis and treatment of these diseases remains limited. The geroscience field is actively investigating geriomics to aid in distinguishing biological and chronological aging. This session will highlight biological aging assessments for hematologic disease which will be crucial for the identification of targets and development of therapies for this specific population.
