We teach a strategy to obtain large quantities of desired APCs, activated B cells, which are superior in their capacity to present tumor protein antigen in a multiadministration protocol. Human B cells can be obtained from peripheral blood in large numbers. These cells can be activated in vitro by coculture with CD40L (CD40-B cells) and an immunosuppressive agent such as cyclosporin A. They can expanded up to 1x103 to 1x104 fold in 2 weeks or 1x105 to 1x106 fold in 2 months. We demonstrate these cells are most efficient APCs comparable to DCs in stimulating allogeneic CD4+ CD45RA+, CD4+ CD45RO+, and CD8+ T cells. In contrast to DCs, CD40-B cells are fully functional even in the presence of immunosuppressive cytokines such as IL-10 and TGFbeta.

The invention provides an antigen-antibody complex for preventing and/or treating avian influenza, which comprises inactivation avian influenza totiviruses which are used as antigen and an immune body thereof, and the mass concentration ratio of the antigen and the immune body is more than 1. After entering organisms to perform initial immunization, the antigen-antibody complex stimulates the organisms again to induce immunoreaction, and immune response is quick in speed and strong in reaction; the antigen-antibody complex used as a carrier is more favorable for capturing and presenting antigen presenting cells and can also strengthen a breeder reaction of T cells effectively; purified totiviruses used as the antigen increase the molecular weight of the complex, are more favorable for ingestion of immunocyte of the organisms on the antigen, cause the more extensive immunoreaction quickly, and have a significance for preventing avian influenza viruses of which the antigen is easy for variation. A preparation of the antigen-antibody complex does not need to use solid carriers, does not cause intense stimulus on the organisms or initiates the organisms to generate an adverse reaction, and is simple to prepare and safe and convenient to use.

The invention discloses recombinantly-expressed Akkermansia membrane protein Amuc_1100 and an application thereof. The invention recombinantly expresses the Akkermansia membrane protein Amuc_1100, through animal experiments, we find that oral administration of the Akkermansia membrane protein Amuc_1100 can significantly improve the body weight of mice, increase colon length and crypt depth, and activate proliferation of intestinal stem cells to protect mice from colitis damage. Isolation of lymphocytes from the lamina propria of the colon shows that the proportion of Treg cells is significantly up-regulated and that of Th17 cells is significantly down-regulated, proving that Amuc_1100 can restore colon damage by adjusting the proportion of immune cells Treg/Th17. Therefore, the protein isexpected to be developed into a protein product for preventing or treating colitis.
