    摘要: Disclosed herein are recombinant CMV vectors comprising heterologous antigens and microRNA recognition elements to silence expression of CMV genes in the presence of microRNA derived from myeloid cells, an active UL128 protein and an active UL130 protein. Also disclosed are recombinant CMV vectors comprising heterologous antigens and microRNA recognition elements to silence expression of CMV genes in the presence of microRNA derived from myeloid cells, an inactive UL128 protein and an inactive UL130 protein. Also disclosed are methods of generating an unconventional immune response using these vectors. Such an immune response is characterized by generation of a CD8+ T cell response that is predominantly restricted by MHC-II.

    摘要: CMV vectors comprising a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), and an active UL128 protein (or an ortholog thereof) but lacking an active UL130 protein (or an ortholog thereof) are provided. CMV vectors comprising a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), and an active UL130 protein (or an ortholog thereof) but lacking an active UL128 protein are also provided. In addition, methods of using CMV vectors to generate an immune response characterized as having at least 10% of the CD8+ T cells directed against epitopes presented by MHC Class II are provided.A clean version of the amended Abstract is provided below:CMV vectors comprising a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), and an active UL128 protein (or an ortholog thereof) but lacking an active UL130 protein (or an ortholog thereof) are provided.
