Zusammenfassung: | Particulate compositions for delivery, preferably pulmonary, which provide sustained release of antigens such as malarial antigens, preferably DNA and/or peptide and/or protein antigens, have been developed. In the preferred embodiment, aggregate nanoparticles are in the aerodynamic range of 1-5 microns diameter and fly deep into the lungs. As the aggregate particles degrade in the body, MSP-1 and AMA-1 proteins are released into the blood stimulating a humoural immune response. The individual particles in the range of 0.1 micron are preferentially phagocytosed by APCs which express the proteins encoded by AMA-1 and MSP-1 plasmid DNA thereby initiating the cellular immune response that is necessary for a complete immunity. |
