Figure Legend Snippet: Immunological challenge in rats with HEP-DiPalm and ELISA assessment. A set of three rats ( #1, 2, 3 ) then tested for the induction of an IgM or IgG response by ELISA (representative set of assays with averaged triplicate wells with standard deviation is presented). Overall, the signal from sera of rats before and after injection with HEP-DiPalm micelles (prelipid, white ; postlipid, black ) tested in the control wells coated with bovine serum albumin ( BSA ) was equivalent to the wells coated with HEP-BSA ( HEP ) or HEP-DiPalm ( DiPalm ) indicating that HEP is not significantly immunogenic, therefore, should be useful in multidose or long-term therapeutics.

Figure Legend Snippet: Representation of HEP-liposome assembly. Models of HEP-coated liposome assemblies with 13.3-kDa ( top ) and 7-kDa ( bottom ) HEP-lipid, based on typical molecular configurations from equilibrated coarse-grained simulations. The liposome and sugars are represented graphically by equivalent spheres (roughly to scale), and part of the liposome has been cut-away for viewing purposes. Potential interaction proteins are depicted (human serum albumin, HSA ; immunoglobulins IgG or IgM ; middle ), drawn to exact scale using coordinates from the Protein Data Bank. Less surface area is available for direct protein binding to liposomes coated with 0.5 mol% 13.3-kDa HEP-lipid compared to 0.5 mol% 7-kDa HEP-lipid, suggesting increased liposomal protection from clearance by the immune system.

A set of three rats ( #1, 2, 3 ) then tested for the induction of an IgM or IgG response by ELISA (representative set of assays with averaged triplicate wells with standard deviation is presented). Overall, the signal from sera of rats before and after injection with HEP-DiPalm micelles (prelipid, white ; postlipid, black ) tested in the control wells coated with bovine serum albumin ( BSA ) was equivalent to the wells coated with HEP-BSA ( HEP ) or HEP-DiPalm ( DiPalm ) indicating that HEP is not significantly immunogenic, therefore, should be useful in multidose or long-term therapeutics.

Figure Legend Snippet: Representation of HEP-liposome assembly. Models of HEP-coated liposome assemblies with 13.3-kDa ( top ) and 7-kDa ( bottom ) HEP-lipid, based on typical molecular configurations from equilibrated coarse-grained simulations. The liposome and sugars are represented graphically by equivalent spheres (roughly to scale), and part of the liposome has been cut-away for viewing purposes. Potential interaction proteins are depicted (human serum albumin, HSA ; immunoglobulins IgG or IgM ; middle ), drawn to exact scale using coordinates from the Protein Data Bank. Less surface area is available for direct protein binding to liposomes coated with 0.5 mol% 13.3-kDa HEP-lipid compared to 0.5 mol% 7-kDa HEP-lipid, suggesting increased liposomal protection from clearance by the immune system.
