    摘要: The invention provides a protein comprising hepatitis B core antigen (HBcAg) with a sugar attached to an e1 loop. The protein may comprise a first and a second copy of HBcAg in tandem, wherein one or both copies of HBcAg has a sugar attached to the e1 loop. The first copy may have a sugar attached to the e1 loop and the second copy may comprise a peptide epitope in the e1 loop. The protein may be used to induce an immune response against the sugar and hence act as a vaccine.

    摘要: A lentivector has been engineered to express a fusion antigen composed of hepatitis B surface protein (HBsAg) and lgG2a Fc fragment (HBS-Fc-lv) to increase both the magnitude of CD8 response and to induce effective co-activation of CD4 T cells. Immunization with this HBS-Fc-lv caused significant regression of established tumors. Immunological analysis revealed that, compared to HBS-lv without the Fc fragment, immunization with HBS-Fc-lv markedly increased the number of functional CD8 and CD4 T cells and the level of Th1/Tc1 -like cytokines in the tumor, while substantially decreasing the Treg ratio. The favorable immunologic changes in tumor lesions and the improvement of antitumor effects from HBS-Fc-lv immunization were dependent on the CD4 activation, which was Fc receptor mediated. Adoptive transfer of the CD4 T cells from the HBS-Fc-lv immunized mice could activate endogenous CD8 T cells in an IFNy-dependent manner. Endogenous CD4 T cells can be activated by lentivirus expressing Fc-tagged antigen to provide another layer of help, i.e., creating a Th1/Tc1 like pro-inflammatory milieu within the tumor lesion to help the effector phase of immune responses to enhance the antitumor effect.

    摘要: In a first aspect, the present invention relates to the use of a TLR 9 agonist and/or a TLR 4 agonist in a prophylactic or therapeutic vaccine. According to the present vaccination strategy, the TLR 9 agonist and/or TLR 4 agonist is adapted or designed for use as a multiplying jump agent to enhance numbers and functionality of CD8 T cells in a prime-jump vaccination strategy for jump T cell expansion. In particular, the TLR 9 agonist and/or TLR 4 agonist is used as a component to be administered after priming of the individual to be vaccinated. The vaccination strategy is particularly useful against acute and chronic infections with intracellular pathogens or for anti-tumor vaccination. In another aspect, the present invention relates to a kit of part containing a prime agent and a multiplying jump agent according to the present invention.
