Characterization of immunogenic properties of haptenated liposomal model membranes in mice. I. Thymus independence of the antigen. 1979

A J van Houte, and H Snippe, and J M Willers

This paper describes a rather simple coupling method for tripeptide enlarged haptens to phosphatidylethanolamine (PE) and the incorporation of these conjugates into liposomal model membranes (haptenated liposomes). These haptenated liposomes evoke a hapten-specific humoral immune response in mice. The magnitude of the response as measured by the appearance of direct plaque forming cells in the spleen is dependent on the route of immunization and the dose and epitope density of the hapten-PE derivatives. It was not possible to evoke an IgG response after either primary or secondary immunization with haptenated liposomes (as measured by the production of indirect plaques or mercaptoethanol-resistant antibody). These data, in addition to the observations that mice depleted of, or deficient in thymus-derived (T) lymphocytes respond to haptenated liposomes, indicate that these haptenated liposomes are T-cell independent antigens.

D008081	Liposomes	Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

D008567	Membranes, Artificial	Artificially produced membranes, such as semipermeable membranes used in artificial kidney dialysis (RENAL DIALYSIS), monomolecular and bimolecular membranes used as models to simulate biological CELL MEMBRANES. These membranes are also used in the process of GUIDED TISSUE REGENERATION.	Artificial Membranes,Artificial Membrane,Membrane, Artificial
D010714	Phosphatidylethanolamines	Derivatives of phosphatidic acids in which the phosphoric acid is bound in ester linkage to an ethanolamine moiety. Complete hydrolysis yields 1 mole of glycerol, phosphoric acid and ethanolamine and 2 moles of fatty acids.

D006241	Haptens	Small antigenic determinants capable of eliciting an immune response only when coupled to a carrier. Haptens bind to antibodies but by themselves cannot elicit an antibody response.	Hapten,Contact-Sensitizing Agents,Agents, Contact-Sensitizing,Contact Sensitizing Agents
D006462	Hemolytic Plaque Technique	A method to identify and enumerate cells that are synthesizing ANTIBODIES against ANTIGENS or HAPTENS conjugated to sheep RED BLOOD CELLS. The sheep red blood cells surrounding cells secreting antibody are lysed by added COMPLEMENT producing a clear zone of HEMOLYSIS.
