Abstract
The humoral response to bovine serum albumin either encapsulated in or surface-linked to liposomes was studied as a function of dose and protein: lipid ratio. Total immunoglobulin, total IgG, IgM, and the G isotypes, IgG1, IgG2a, and IgG3 were measured during the plateau phase of production after a boosting injection. Although the adjuvant character of liposomes was confirmed regardless of the mode of antigen association, important differences in the response to the two types of liposomal formulations were observed. Our results suggest that surface-linked antigen stimulates the immune system at lower doses than its encapsulated counterpart, is more sensitive to the protein:lipid ratios, and can stimulate the production of particular immunoglobulin isotypes in controlled conditions. Our data support the idea that different pathways of processing are utilized by the two forms of liposomal antigen.
