Liposomes have been used to modify the immunological behaviour of a number of antigens. The present study was designed to evaluate the effect of liposomization of ovalbumin on the induction of Th-1 and Th-2-cell response by monitoring the secretion of lymphokines and IgG Isotypes. Liposomes having varied physicochemical properties (positively and negatively charged, neutral and pH-sensitive) were used for this purpose. Ovalbumin delivered in this way induced preferential secretion of IL-4 and production of antigen-specific IgG1 isotypes. This was observed irrespective of the surface charge properties of the liposomes. Further, the concentration of antigen required for the activation of Th cells was 10(2)- to 10(3)-fold lower after encapsulating it in liposomes. These results suggest that liposomes may prove useful adjuvants to prime Th2-like immune responses.
