Disease model incorporation into an artificial immune system (AIS)
The present invention relates to methods of constructing an integrated artificial immune system that comprises appropriate in vitro cellular and tissue constructs or their equivalents to mimic the tissues of the immune system in mammals. The artificial immune system can be used to test the efficacy of vaccine candidates and other materials in vitro and thus, is useful to accelerate vaccine development and testing drug and chemical interactions with the immune system, coupled with disease models to provide a more complete representation of an immune response.
1. An in vitro two culture cellular system comprising:
a culture of a two- or three-dimensional matrix, comprising lymphoid tissue; and
a culture of diseased cells, wherein said diseased cells are immune system cells, selected from the group consisting of PBMCs, monocytes, macrophages, dendritic cells, lymphocytes, and antigen-presenting cells.
2. The in vitro system of claim 1 , wherein said diseased cells are selected from the group consisting of virally infected cells, bacterially infected cells, tumor cells, and autoimmune disease-afflicted cells.
3. The in vitro system of claim 1 , wherein said diseased cells are virally infected cells.
4. The in vitro system of claim 1 , wherein said diseased cells are bacterially infected cells.
5. The in vitro system of claim 1 , wherein said diseased cells comprise PBMCs derived from blood donors infected with a virus.
6. The in vitro system of claim 1 , wherein said diseased cells comprise PBMCs derived from uninfected blood donors, and wherein said PBMCs are in vitro with a virus.
