Macrophage galactose lectin is critical for Kupffer cells to clear aged platelets

C Deppermann, RM Kratofil, M Peiseler… - Journal of Experimental …, 2020 - rupress.org

Sialylation on O-glycans protects platelets from clearance by liver Kupffer cells

Y Li, J Fu, Y Ling, T Yago… - Proceedings of the …, 2017 - National Acad Sciences
Most platelet membrane proteins are modified by mucin-type core 1-derived glycans (O-

The role of lectins and glycans in platelet clearance

KM Hoffmeister - Journal of thrombosis and haemostasis, 2011 - Wiley Online Library
In recent years, it has become increasingly apparent that the life span of transfused platelets
