    • Recombinant mycobacterial vaccine vehicles capable of expressing DNA of interest which encodes at least one protein antigen for at least one pathogen against which an immune response is desired and which can be incorporated into the mycobacteria or stably integrated into the mycobacterial genome. The vaccine vehicles are useful for administration to mammalian hosts for purposes of immunization. A recombinant vector which replicates in E. coli but not in mycobacteria is also disclosed. The recombinant vector includes 1) a mycobacterial gene or portions thereof, necessary for recombination with homologous sequences in the genome of mycobacteria transformed with the recombinant plasmid; 2) all or a portion of a gene which encodes a polypeptide or protein whose expression is desired in mycobacteria transformed with the recombinant plasmid; 3) DNA sequences necessary for replication and selection in E. coli; and 4) DNA sequences necessary for selection in mycobacteria (e.g., drug resistance). The present invention also relates to two types of recombinant vectors useful in introducing DNA of interest into mycobacteria, where it is expressed. One type of vector is a recombinant plasmid capable of replicating as a plasmid in E. coli and of lysogenizing a mycobacterial host. The other type of vector is a recombinant plasmid which can be introduced into mycobacteria, where it is stably maintained extrachromosomally.
    • 能够表达目的的DNA的重组分枝杆菌疫苗载体,其编码针对至少一种需要免疫应答的至少一种病原体的至少一种蛋白质抗原并且可以并入分枝杆菌中或稳定整合到分枝杆菌基因组中。 疫苗载体用于哺乳动物宿主用于免疫的目的。 还公开了在大肠杆菌中但不在分枝杆菌中复制的重组载体。 重组载体包括1)与用重组质粒转化的分枝杆菌基因组中与同源序列重组所必需的分枝杆菌基因或其部分; 2)编码在用重组质粒转化的分枝杆菌中表达所需的多肽或蛋白质的基因的全部或部分; 3)在大肠杆菌中复制和选择所需的DNA序列; 和4)在分枝杆菌中选择所需的DNA序列(例如耐药性)。 本发明还涉及可用于将感兴趣的DNA引入分枝杆菌的两种类型的重组载体,其中它被表达。 一种载体是能够在大肠杆菌中作为质粒复制并使分解细菌宿主溶解的重组质粒。 另一种载体是可以引入分枝杆菌的重组质粒,其在染色体外稳定地保持。

    • The invention provides compositions and methods of use to enhance reprogramming of mammalian cells. Certain compositions and methods of the invention are of use to enhance generation of induced pluripotent stem cells by reprogramming somatic cells. Certain compositions and methods of the invention are of use to enhance reprogramming of pluripotent mammalian cells to a differentiated cell type. Certain compositions and methods of the invention are of use to enhance reprogramming of differentiated mammalian cells of a first cell type to differentiated mammalian cells of a second differentiated cell type. The reprogrammed somatic cells are useful for a number of purposes, including treating or preventing a medical condition in an individual. The invention further provides methods for identifying an agent that enhances or contributes to reprogramming mammalian cells. Certain of the inventive compositions and methods relate to inhibiting histone methylation.
