20090104223 | Method for Obtaining Antigenic Aggregates and the Use Thereof in Formulations - The invention relates to a method for obtaining aggregated antigenic structures that are capable of enhancing an immune response to aggregate antigens administered systemically and/or mucosally generating powerful immune response and to the chemical structures resulting from the application of said method, to the formulations obtained from such structures and their use. The method describes the obtention of novel aggregate antigenic structures by using aggregating, delipidating or oxidating agents or compounds enabling the release of lipids from the particles and their heterogeneous aggregation, wherein aggregates with particle sizes of between 30 and 500 nm are subsequently selected by means of a molecular exclusion process. The aggregation state can also be provoket inside the yeast by changing incubation conditions. The resulting structures can be used conveniently adjuvated or in a formulation in which several antigens can be introduced, wherein synergism between said components is found with respect to the immunogenicity of the response obtained. The preparation may also contain stabilizers and preservatives. The resulting antigenic structures can be used in the pharmaceutical industry as preventive or therapeutic vaccine formulation both for human and veterinary use and as part of diagnostic system. | 04-23-2009 |

20120308615 | FORMULATION OF HEPATITIS B VIRUS ANTIGENS FOR CELLULAR STIMULATION FOLLOWED BY THERAPEUTIC IMMUNIZATION - The present invention is related with the field of the therapeutic immunization, specifically with the employment of a new formulation of antigens of the Hepatitis B Virus (HBV) for the cellular stimulation. The formulation is formed by the surface antigens (HBsAg) precipitated in suspension and the nucleocapsid (HBcAg) of the HBV. The formulation contains these antigens like suspended particles of sizes less than 500 nm and higher than 500 nm, in a mixture where the proportion among the particles of the mentioned sizes is among 50%-50% and 80%-20%, respectively. The selection of a range of sizes of particles allows that the levels of stimulation of several cellular types are maximized. Additionally, a cellular stimulation method is described with this formulation, and the later passive immunization of patients with chronic Hepatitis B, based on the maximum stimulation in vivo or in vitro using heterologous or autologous cells (dendritic cells, B cells and macrophages). The cells stimulated with this formulation are transferred to patients chronically infected with the HBV. | 12-06-2012 |
