  • Publication number: 20140121587
    Abstract: Several needle assemblies and intracellular delivery devices that are used for the delivery of prophylactic and/or therapeutic material (i.e., delivered agents) into a tissue of a subject are disclosed. Preferably, the needle assemblies and/or the intracellular delivery devices comprise needles and/or needle electrodes, which are disposed in an array (e.g., a Y-type array having three outer needles and a center needle), wherein each needle in the array has a closed end and a plurality of apertures along each needle barrel, and the apertures on the needle barrels of the outer needles of the array are positioned to deliver the delivered agent toward the apertures of the center needle and/or an adjacent needle, but not outside of the active zone defined by the area within the needle array and the apertures on the needle barrel of the center needle are positioned to deliver the delivered agent toward the outer needles.

  • Publication number: 20130202554
    Abstract: Disclosed herein are isolated nucleic acids, compositions of isolated nucleic acids, and compositions of polypeptides that are useful for the generation, enhancement, or improvement of an immune response to a target antigen. Some embodiments of the compositions include hepatitis B core antigen (HBcAg) protein and a heterologous protein antigen. In some embodiments, an isolated nucleic acid encoding hepatitis B core antigen (HBcAg) protein and a heterologous protein antigen is disclosed. Also disclosed herein are methods of administering the composition or isolated nucleic acid to generate an immune response, where HBcAg acts as adjuvant to improve the immune response to the heterologous protein. In certain embodiments, the HBcAg is as a stork or heron hepatitis antigen.
