Gangliosides are physiological components of the outer cell membrane. In the present study, the role of ganglioside expression during differentiation of human mast cells was evaluated. After 11 days of culture in medium known to induce mast cell differentiation, 70% of peripheral blood mononuclear cells (PBMC) showed positive staining for the high affinity(More)
A series of well-defined polymer-drug conjugates were prepared in order to modify the physical properties of a known cytotoxic drug, 7-ethyl-10-hydroxycamptothecin (SN-38), the active metabolite of irinotecan (CPT-11). Reversible addition-fragmentation chain transfer (RAFT) polymerisation was used to covalently and site-specifically append a defined(More)
