Unlike other types of blood components, refrigeration of platelets leads to their rapid clearance from the circulation after transfusion. Platelets must therefore be stored at room temperature, a serious limitation to their use for transfusions. Viktoria Rumjantseva et al. now dissect two platelet clearance pathways by which exposed carbohydrate residues on platelets are recognized by receptors on liver macrophages and hepatocytes, which differentially control the clearance of short-term– and long-term–refrigerated platelets.
