The present invention provides a treatment apparatus. The apparatus contains a reservoir or generator for a treatment solution, a mechanism for delivering the treatment solution to a wound site, and a mechanism for applying the solution to a wound, tissue, bone or surgical cavity for treatment. The apparatus may apply the solution (e.g., a solution containing hypohalous acid) with, for example, an occlusive wound dressing, pulsative lavage device, hydrotherapy, hydrosurgical device, and/or ultrasound. A waste container may be operably connected to the apparatus for collecting waste from the wound by run-off, or by applying negative pressure (e.g. a vacuum). Because the apparatus of the invention can optionally be portable or mobile, the invention is suitable for use in hospitals and nursing homes, as well as for home wound care. The invention also provides a method for treating a wound (or other area needing treatment), and/or for reducing wound bioburden, by supplying a hypochlorous acid solution to the site, such as a wound colonized or infected with drug resistant bacteria, before, during, or after negative pressure wound therapy.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

This invention provides fully human monoclonal antibodies that recognize HER2. The invention further provides methods of using such monoclonal antibodies in a variety of therapeutic, diagnostic, and prophylactic indications.

The invention discloses a CIK cell, as well as a preparation method and a cell preparation thereof. The method for preparing the CIK cell comprises the following steps: placing a separated mononuclear cell in a culture fluid containing phytohemagglutinin; transplanting the mononuclear cell into a culture flask enveloped by antiCD3 monoclonal antibody and antiCD28 monoclonal antibody after the cell is cultured for 24 to 72 hours; and adding a culture fluid containing IL-1alpha and IL-2 into the culture flask to keep on culturing for 5 to 15 days, and separating the cells into different flasks to be cultured every 2 to 3 days. The CIK cell prepared by the method has the characteristics of obvious improved cell proliferation, great increase of CD8 cell proportion, wide antineoplastic spectrum and strengthened antineoplastic activity. The CIK cell and the cell preparation can effectively prevent the metastasis and the recrudescence for of postoperative patients with tumor, can be combined with chemicotherapy to effectively reduce toxic and side effects of the chemicotherapy, strengthens the survivability tolerance of the patients to improve healing efficacy, and can obviously prolong lifecycle to of end-stage patients so as to improve the life living quality.

The present invention relates to method for depletion of CD137 positive cells using an anti-CD137 antibody-toxin complex, and more particularly, to a method for selective depletion of CD137 positive cells, comprising the step of contacting an anti-CD137 antibody-toxin complex with the CD137 positive cells. The method for selective depletion of CD137 positive cells in accordance with the present invention can be useful to prevent or treat various diseases including immune diseases mediated by the activation of the CD137 positive cells because this method is excellent in delivering a complex of an anti-CD137 antibody, specific to CD137 molecules, and a toxin to CD137 expressing cells and selectively killing the CD137 positive cells alone and is also excellent in suppressing cell proliferation.

The present invention provides a recombinant pox virus composition comprising a nucleic acid sequence encoding chemokines as costimulatory molecules. The present invention further provides a host cell, a host animal, and a pharmaceutical composition comprising the recombinant pox virus composition. Also provided is a method for treating or preventing a neoplasm or infectious disease in a subject, using the pox virus composition and/or an SLC agent. Additionally, the present invention provides a method for promoting the proliferation of a CD4 T cell, comprising administering to the cell an SLC agent in an amount effective to directly promote the proliferation of the cell. Finally, the present invention provides a method for treating or preventing a neoplasm or infectious disease in a subject using cultured CD4 T cells.

The present invention provides defined serum-free cell culture media useful in culturing fibroblasts, especially articular chondrocytes, that avoid problems inherent in the use of serum-containing media. The defined media comprise platelet-derived growth factor (PDGF), chemically defined lipids, oncostatin M (OSM), interleukin-6 (IL-6), leukemia inhibitory factor (LIF), or combinations of these compounds. In another aspect, the present invention also provides tissue culture methods that comprise incubating chondrocytes in the defined serum-free media. The methods enhance attachment and proliferative expansion of chondrocytes seeded at low density while maintaining their redifferentiation potential.
