  • Patent number: 8241621
    Abstract: Disclosed are cells, methods of modulating cells, and therapeutic uses of the cells for the immune modulation of mammals in need thereof. Immune modulation including alteration of cytokine profile, cytotoxic activity, antibody production and inflammatory states is achieved through the administration of various cell types that have been unmanipulated or manipulated in order to endow specific biological activity. Cellular subsets and administration of the subsets in combination with various agents are also provided. One embodiment teaches the previously unknown finding that adipose tissue derived mononuclear cells contain T cells with immune regulatory properties that alone or synergistically with various stem cells induce immune modulation upon administration. Another embodiment is the finding that stimulation of stem cell activation results in stem cell secondary activation of immune modulatory cells, one type which is T regulatory cells (Tregs).

  • Patent number: 8231868
    Abstract: Methods are provided for suppressing the immune system response in recipients of transplanted organs, tissues or cells. An extracorporeal quantity of blood from the intended transplant recipient is treated to induce monocytes contained in the blood to differentiate and form dendritic cells. The maturation of the dendritic cells is truncated at a stage where the dendritic cells can inactivate T cell clones which would otherwise generate an undesired immune system response. The immature dendritic cells can be directly administered to the transplant recipient, or the dendritic cells can be co-incubated with the bone marrow or stem cell preparation, prior to transplantation, in order to suppress or eliminate anti-recipient donor T cells contaminating the bone marrow or stem cell preparation. The methods can be used to suppress graft versus host disease in recipients of transplanted bone marrow or stem cells, or to suppress rejection of transplanted organs or tissue.

  • Publication number: 20120128646
    Abstract: The present invention is related to the development and treatment of autoimmune disease. Autoimmune diseases can result from tissue damage caused by the activation of autoreactive T cells by autoantigens. For example, peptide fragments of naturally occurring proteins (i.e., for example, chromogranin A) may activate autoreactive T cells that result in the destruction of pancreatic ? islet cells, possibly by the release of inflammatory cytokines (i.e., for example, interferon-?). One naturally occurring biologically active chromogranin A peptide fragment, WE14, may comprise a diabetogenic autoantigen. Truncation and extension analysis of WE14 indicates that the stimulating binding register of WE14 occupies only half of the mouse IAg7 peptide binding groove, leaving positions p1 to p4 empty.

  • Publication number: 20120107294
    Abstract: Provided is a composition for in vivo transplantation for the treatment of human cervical cancer, comprising mononuclear cells derived from umbilical cord blood and a pharmaceutically acceptable carrier. When the umbilical cord blood-derived mononuclear cells are transplanted in vivo, cervical cancer can be effectively treated. In particular, the mononuclear cells derived from the umbilical cord blood retain high differentiation and proliferation abilities and exhibit very low graft-versus-host (GVH) reactions which are side effects caused by transplantation, and thus, can be transplanted to many patients.

  • Publication number: 20120093792
    Abstract: The present invention provides an immunotherapeutic agent and immunotherapy allowing the extension of the survival time of patients with pancreatic cancer. The immunotherapy of the present invention is characterized by comprising the steps of culturing peripheral blood lymphocytes of a patient with pancreatic cancer by stimulating the lymphocytes with an anti-CD3 antibody and an anti-CD52 antibody, thereby to obtain an immunotherapeutic agent, and administering at least four infusions of the resultant immunotherapeutic agent to the same patient, wherein each of the infusions of the immunotherapeutic agent comprises at least 15×109 cells of activated lymphocytes, the percentage of CD3? CD56+ NK cells in the activated lymphocytes is at least 30%, and the administration of the immunotherapeutic agent is begun for the patient who is in at least one state of two or more particular immunocompromised states.

  • Patent number: 8153120
    Abstract: The present invention relates to the discovery of novel methods of inducing a natural killer (NK) cell-mediated immune response and increasing NK activity in a mammal for the treatment of tumors and virus infections. The method comprises the steps of isolating peripheral blood mononuclear cells (PBMCs) from the subject, exposing the PBMCs in vitro to protein conjugate comprising granulocyte macrophage colony stimulating factor (GM-CSF) covalently linked to a soluble peptide antigen, under conditions effective to activate the PBMCs, and administering the activated PBMCs to the subject. The invention also relates to a method of detecting in a subject a cytotoxic NK cell-meditated immune response or NK cell activity in vitro by CD336 expression and/or lysis of the K562 tumor line. The invention further relates to a method for determining whether a subject has had a therapeutically effective response to a protein conjugate by assessing the NK activity of activated PBMCs from the subject.

  • Publication number: 20120082715
    Abstract: A composition comprising a glassified, stabilized particle preparation having a low water activity (between about 0.1 and 0.9) is provided. The preparations provide improved products with enhanced storage stability, less expensive cost of processing, and extended shelf life. The glassified, stabilized particle preparations are particularly efficacious in the preparation of perishable products, especially pharmaceutical agents, such as human blood and blood products (e.g., red blood cells). A single emulsion process comprising a 2-phase system for preserving food and pharmaceutical products is also provided. Stabilized biological products as glassified beads are also provided, as well as a method for rehydrating and/or reconstituting the glassified beads to provide useful and fully active reconstituted and/or rehydrated materials is also presented.

  • Publication number: 20120082687
    Abstract: Disclosed is a method to recover an antigen presenting cells (APCs) and immune cells rich mixture (AIM) from peripheral blood mononuclear cells (PBMC) mobilized with one or more cell adhesion inhibitors for the preparation of an AIM vaccine or an AIM adoptive immunotherapy preparation. In addition, AIM mobilization can be enhanced by priming, simultaneously or in sequence, one or more of a combination of different chemical compounds, cytokines, hormones, growth factors, etc. The interaction of chemokines and chemokine receptors enable tumor cells attachment or in close proximity to antigen presenting cells and immune cells which possess similar receptors in a micro niche environment. Severing the chemokine/chemokine receptor linkage by a cell adhesion inhibitor will release these specifically primed cell mixtures into the peripheral blood. The collection of these cells from the peripheral blood has never been described and is the basis of this invention.

  • Patent number: 8142772
    Abstract: This invention is directed to therapeutic compositions containing non-MHC-restricted Tcells/NK-cells in combination with MHC-restricted T-cells and especially to therapeutic compositions, which comprise LAK cells. Furthermore, the present invention is directed to the use of the above combination in the treatment of tumors in humans, which tumors show a missing, low or aberrant expression of MHC class Ia or Ib molecules. By using the aforementioned compositions/combinations it is possible to provide a balanced selective pressure against emergence of tumor cell variants that would otherwise escape immune detection.
